Abstract

 
This study evaluated distillers grain (DG) by-products produced in different ethanol plants and supplemented in animal diets in Texas, based on samples analyzed from 2008 to 2014. The samples were assessed for concentration, occurrence, and prevalence of selected nutrients and contaminants. Protein and sulfur contents of DG were largely different between corn and sorghum by-products as well as wet distillers grain with solubles and dry distillers grain with solubles (DDGS), indicating a significant effect of grain feedstock and dry-grind process stream on DG composition and quality. Salmonella was isolated in 4 DDGS samples out of a total of 157 DG samples, a percentage (2.5%) that is much lower than the percentage of Salmonella-positive samples found in other feed samples analyzed during the same period. A small amount of virginiamycin residue was found in 24 corn DDGS, 1 corn wet distillers grain with solubles, and 2 sorghum DDGS samples out of 242 samples in total. One sorghum DDGS sample out of 168 DG samples was contaminated with bovine spongiform encephalopathy, but the transmission route of the bovine spongiform encephalopathy agent could not be clearly defined. The concentrations of aflatoxin and fumonisin DG by-products averaged 3.4 μg/kg and 0.7 mg/kg, respectively. Among contaminated corn DG samples, five DDGS samples for aflatoxin contained a higher concentration than the U.S. Food and Drug Administration action level for use in animal feed, whereas no sample for fumonisin was found above the action level. The study results raised some important issues associated with the quality and use of DG by-products, suggesting several approaches and strategies for their effective and safe use as a feed ingredient to promote animal and human health and welfare.

Statement on Texas Cow With Central Nervous System Symptoms

 

On Friday, April 30 th , the Food and Drug Administration learned that a cow with central nervous system symptoms had been killed and shipped to a processor for rendering into animal protein for use in animal feed.

 

FDA, which is responsible for the safety of animal feed, immediately began an investigation. On Friday and throughout the weekend, FDA investigators inspected the slaughterhouse, the rendering facility, the farm where the animal came from, and the processor that initially received the cow from the slaughterhouse.

 

FDA's investigation showed that the animal in question had already been rendered into "meat and bone meal" (a type of protein animal feed). Over the weekend FDA was able to track down all the implicated material. That material is being held by the firm, which is cooperating fully with FDA.

Dear Madam Secretary:

 

I am writing to express concern that the recent failure of the U.S. Department of Agriculture (USDA) to test a Texas cow with neurological syrnptoms for bovine spongifonnencephalopathy (BSE) may reflect wider problems in the surveillance program. USDA apparently does not keep track of how many cows condemned for central nervous system symptoms are tested for BSE nor does it require that suspect carcasses be held pending testing...

U.S. Department of Agriculture (USDA) Food and Drug Administration (FDA)

 

Investigation Results of Texas Cow That Tested Positive for Bovine Spongiform Encephalopathy (BSE) Aug. 30, 2005

 

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) and the U.S. Department of Health and Human Services' Food and Drug Administration (FDA) have completed their investigations regarding a cow that tested positive for bovine spongiform encephalopathy (BSE) in June 2005. The agencies conducted these investigations in collaboration with the Texas Animal Health Commission and the Texas Feed and Fertilizer Control Service.

 

Our results indicate that the positive animal, called the index animal, was born and raised on a ranch (termed the "index farm") in Texas. It was a cream colored Brahma cross approximately 12 years old at the time of its death. It was born prior to the implementation of the 1997 feed ban instituted by FDA to help minimize the risk that a cow might consume feed contaminated with the agent thought to cause BSE. The animal was sold through a livestock sale in November of 2004 and transported to a packing plant. The animal was dead upon arrival at the packing plant and was then shipped to a pet food plant where it was sampled for BSE. The plant did not use the animal in its product, and the carcass was destroyed in November 2004.

 

APHIS attempted to trace all adult animals that left the index farm after 1990, as well as all progeny born within 2 years of the index animal's death. Together, these animals are called animals of interest.

 

During the course of the investigation, USDA removed and tested a total of 67 animals of interest from the farm where the index animal's herd originated. All of these animals tested negative for BSE. 200 adult animals of interest were determined to have left the index farm. Of these 200, APHIS officials determined that 143 had gone to slaughter, two were found alive (one was determined not to be of interest because of its age and the other tested negative), 34 are presumed dead, one is known dead and 20 have been classified as untraceable. In addition to the adult animals, APHIS was looking for two calves born to the index animal. Due to record keeping and identification issues, APHIS had to trace 213 calves. Of these 213 calves, 208 entered feeding and slaughter channels, four are presumed to have entered feeding and slaughter channels and one calf was untraceable.

 

To determine whether contaminated feed could have played a role in the index animal's infection, FDA and the Texas Feed and Fertilizer Control Service conducted a feed investigation with two main objectives: 1) to identify all protein sources in the animal=s feed history that could potentially have been the source of the BSE agent, and 2) to verify that cattle leaving the herd after 1997 were identified by USDA as animals of interest and were rendered in compliance with the 1997 BSE/ruminant feed rule.

 

The feed history investigation identified 21 feeds or feed supplements that were used on the farm since 1990. These feed ingredients were purchased from three retail feed stores and were manufactured at nine feed mills. This investigation found that no feed or feed supplements used on the farm since 1997 were formulated to contain prohibited mammalian protein. Due to this finding, FDA has concluded that the animal was most likely infected prior to the 1997 BSE/ruminant feed rule.

 

The investigation into the disposition of herd mates from this farm involved visits to nine slaughter plants and eight rendering plants. The investigation found that all of the rendering plants were operating in compliance with the BSE/ruminant feed rule. A review of the inspection history of each of these rendering firms found no violations of the FDA feed ban rule.

 

APHIS and FDA are very pleased with the results of their investigations, which show the animals of interest did not present a threat to livestock and that the ruminant feed rule is being followed. The U.S. maintains an interlocking system of safeguards designed to prevent BSE from entering the human and animal food chain. USDA also remains vigilant in its attempt to find BSE in the United States. To date, there have been more than 450,000 animals tested in the last 14 months and only two BSE positive animals found in this country.

State-Federal Team Responds to Texas BSE Case

 

The US Department of Agriculture announced June 29 that genetic testing has verified that an aged cow that tested positive for Bovine Spongiform Encephalopathy or BSE originated from a Texas beef cattle herd. Tissues for laboratory testing were initially collected from the animal in November 2004, and the carcass was incinerated and did not enter the human food, animal feed or fertilizer supply system. While tests in November indicated the animal did not have BSE, retesting in England in June confirmed the animal had the disease. The Texas Animal Health Commission (TAHC), the state’s livestock and poultry health regulatory agency, and USDA have jointly assigned a state-federal team to conduct the epidemiological investigation and response.

 

“The TAHC and US Department of Agriculture’s Veterinary Services are working with a complement of experts from federal and state animal health, food safety, public health and feed regulatory agencies to ensure the continued safety and wholesomeness of our meat supply,” said Dr. Bob Hillman, Texas state veterinarian and executive director of the TAHC, the state’s livestock and poultry health regulatory agency. “Epidemiological investigations are thorough and focus on verifying the herd of origin, and when, where and how the animal and potentially, any herd mates, were exposed to the abnormal prion, or disease agent, that causes BSE. Additionally, epidemiology investigations trace the infected animal’s movement and herd mates. Animals potentially exposed to the disease will be depopulated, with proper disposal. The animals will not be introduced into the human or animal food chain.”

 

The USDA’s BSE testing protocol requires testing of emaciated or injured cattle, cattle that exhibit central nervous system disorder, cattle unable to rise or to walk normally, and cattle that die of unknown causes. Since June 1, 2004, brain tissue samples from more than 394,000 cattle have been tested in the U.S. and were negative for BSE. Of those, 38,320 were tested in Texas, Dr. Hillman noted. BSE surveillance has been conducted in the U.S. since l990.

 

The U.S. has taken preventive measures against the introduction of BSE since l989, when prohibitions were placed on cattle and other ruminants from BSE-affected countries, noted Dr. Hillman. In 1997, the importation ban was extended to all of Europe.

 

Dr. Hillman said the U.S. Food and Drug Administration (FDA) in 1997 banned the use of ruminant-derived protein (from animals such as cattle and sheep) in feed for cattle and other ruminants. There is no evidence that BSE spreads from live animal to animal in the herd, but cattle can be exposed by eating feed that contains rendered protein from infected animals. “These measures taken by the USDA and the FDA are safeguards that work to protect livestock, and ultimately, our meat supply,” he said.

THE USDA JUNE 2004 ENHANCED BSE SURVEILLANCE PROGRAM WAS TERRIBLY FLAWED ;

 

CDC DR. PAUL BROWN TSE EXPERT COMMENTS 2006

 

In an article today for United Press International, science reporter Steve Mitchell writes:

 

Analysis: What that mad cow means

 

By STEVE MITCHELL UPI Senior Medical Correspondent

 

WASHINGTON, March 15 (UPI) -- The U.S. Department of Agriculture was quick to assure the public earlier this week that the third case of mad cow disease did not pose a risk to them, but what federal officials have not acknowledged is that this latest case indicates the deadly disease has been circulating in U.S. herds for at least a decade.

 

The second case, which was detected last year in a Texas cow and which USDA officials were reluctant to verify, was approximately 12 years old.

 

These two cases (the latest was detected in an Alabama cow) present a picture of the disease having been here for 10 years or so, since it is thought that cows usually contract the disease from contaminated feed they consume as calves. The concern is that humans can contract a fatal, incurable, brain-wasting illness from consuming beef products contaminated with the mad cow pathogen.

 

"The fact the Texas cow showed up fairly clearly implied the existence of other undetected cases," Dr. Paul Brown, former medical director of the National Institutes of Health's Laboratory for Central Nervous System Studies and an expert on mad cow-like diseases, told United Press International. "The question was, 'How many?' and we still can't answer that."

 

Brown, who is preparing a scientific paper based on the latest two mad cow cases to estimate the maximum number of infected cows that occurred in the United States, said he has "absolutely no confidence in USDA tests before one year ago" because of the agency's reluctance to retest the Texas cow that initially tested positive.

 

USDA officials finally retested the cow and confirmed it was infected seven months later, but only at the insistence of the agency's inspector general.

 

"Everything they did on the Texas cow makes everything they did before 2005 suspect," Brown said.

 

Despite this, Brown said the U.S. prevalence of mad cow, formally known as bovine spongiform encephalopathy, or BSE, did not significantly threaten human or cattle health.

 

"Overall, my view is BSE is highly unlikely to pose any important risk either in cattle feed or human feed," he said.

 

However, Jean Halloran of Consumers Union in Yonkers, N.Y., said consumers should be troubled by the USDA's secrecy and its apparent plan to dramatically cut back the number of mad cow tests it conducts.

 

"Consumers should be very concerned about how little we know about the USDA's surveillance program and the failure of the USDA to reveal really important details," Halloran told UPI. "Consumers have to be really concerned if they're going to cut back the program," she added.

 

Last year the USDA tested more than 300,000 animals for the disease, but it has proposed, even in light of a third case, scaling back the program to 40,000 tests annually.

 

"They seem to be, in terms of actions and policies, taking a lot more seriously the concerns of the cattle industry than the concerns of consumers," Halloran said. "It's really hard to know what it takes to get this administration to take action to protect the public."

 

The USDA has insisted that the safeguards of a ban on incorporating cow tissue into cattle feed (which is thought to spread the disease) and removal of the most infectious parts of cows, such as the brain and spinal cord, protect consumers. But the agency glosses over the fact that both of these systems have been revealed to be inadequately implemented.

 

The feed ban, which is enforced by the Food and Drug Administration, has been criticized by the Government Accountability Office in two reports, the most recent coming just last year. The GAO said the FDA's enforcement of the ban continues to have weaknesses that "undermine the nation's firewall against BSE."

 

USDA documents released last year showed more than 1,000 violations of the regulations requiring the removal of brains and spinal cords in at least 35 states, Puerto Rico and the Virgin Islands, with some plants being cited repeatedly for infractions. In addition, a violation of similar regulations that apply to beef exported to Japan is the reason why Japan closed its borders to U.S. beef in January six weeks after reopening them.

 

Other experts also question the adequacy of the USDA's surveillance system. The USDA insists the prevalence of mad cow disease is low, but the agency has provided few details of its surveillance program, making it difficult for outside experts to know if the agency's monitoring plan is sufficient.

 

"It's impossible to judge the adequacy of the surveillance system without having a breakdown of the tested population by age and risk status," Elizabeth Mumford, a veterinarian and BSE expert at Safe Food Solutions in Bern, Switzerland, a company that provides advice on reducing mad cow risk to industry and governments, told UPI.

 

"Everybody would be happier and more confident and in a sense it might be able to go away a little bit for (the USDA) if they would just publish a breakdown on the tests," Mumford added.

 

UPI requested detailed records about animals tested under the USDA's surveillance plan via the Freedom of Information Act in May 2004 but nearly two years later has not received any corresponding documents from the agency, despite a federal law requiring agencies to comply within 30 days. This leaves open the question of whether the USDA is withholding the information, does not have the information or is so haphazardly organized that it cannot locate it.

 

Mumford said the prevalence of the disease in U.S. herds is probably quite low, but there have probably been other cases that have so far gone undetected. "They're only finding a very small fraction of that low prevalence," she said.

 

Mumford expressed surprise at the lack of concern about the deadly disease from American consumers. "I would expect the U.S. public to be more concerned," she said.

 

Markus Moser, a molecular biologist and chief executive officer of Prionics, a Swiss firm that manufactures BSE test kits, told UPI one concern is that if people are infected, the mad cow pathogen could become "humanized" or more easily transmitted from person to person.

 

"Transmission would be much easier, through all kinds of medical procedures" and even through the blood supply, Moser said.

An Arizona meat processing company and its owner pled guilty in February 2007 to charges of theft of Government funds, mail fraud, and wire fraud. The owner and his company defrauded the BSE Surveillance Program when they falsified BSE Surveillance Data Collection Forms and then submitted payment requests to USDA for the services. In addition to the targeted sample population (those cattle that were more than 30 months old or had other risk factors for BSE), the owner submitted to USDA, or caused to be submitted, BSE obex (brain stem) samples from healthy USDA-inspected cattle. As a result, the owner fraudulently received approximately $390,000. Sentencing is scheduled for May 2007.

2009 UPDATE ON ALABAMA AND TEXAS MAD COWS 2005 and 2006

 


 

LET's go back to the infamous TOKEN, charade, that happened on January 30, 2001, at the Texas Purina feed lot around Gonzales. NOW remember, this thing was set up from the word go, as to some big showing that the FDA was DOING SOMETHING BIG. let's look at exactly what was said then, and then i will run some figures by you, of what banned mad cow feed has gone into commerce, of which most was fed out. but, as wrong as the comments made were about what amount of infectious material will kill a cow in this statement, even if you were to go by those wrong figures of about .......... oh what was it ???

 

''FDA has determined that each animal could have consumed, at most and in total, five-and-one-half grams - approximately a quarter ounce -- of prohibited material. These animals weigh approximately 600 pounds.''

 


 

you can take that with how ever many grains of salt you wish, but i read that as saying, it was only 5 1/2 grams, and the old cow ways 600 pounds, so know way that even if the feed was tainted, there was not enough to cause disease. the fda, usda et al, knew at that exact moment when they wrote that statement, they knew then that the 5 1/2 grams was enough to kill a small herd of cows. it was old science. but again, they chose to deceive. THIS WAS 2001, and it's now 2009, and they still are choosing to deceive, and the new administration appears willing to continue the USA mad cow charade. NOW, since the charade at the purina mill in 2001, i am going to list a few figures of suspect, banned mad cow feed that went out into commerce, even in 2008, 2007, 2006, back a few years, and you can compare, what enormous amounts of banned suspect mad cow feed and other products continue to go out. when you consider, and they knew all along, that .005 grams is lethal, my God, how much of this poison was consumed? WASHINGTON, June 26, 2008 - Beltex Corporation, doing business as Frontier Meats, a Fort Worth, Texas, establishment, is recalling approximately 2,850 pounds of fresh cattle heads which may contain specified risk materials (SRMs), the U.S. Department of Agriculture's Food Safety and Inspection Service announced today.

An example of an OAI inspection classification would be findings of manufacturing procedures insufficient to ensure that ruminant feed is not contaminated with prohibited material. Inspections classified with OAI violations will be promptly re-inspected following the regulatory sanctions to determine whether adequate corrective actions have been implemented.

Risk of oral infection with bovine spongiform encephalopathy agent in primates Corinne Ida Lasmézas, Emmanuel Comoy, Stephen Hawkins, Christian Herzog, Franck Mouthon, Timm Konold, Frédéric Auvré, Evelyne Correia, Nathalie Lescoutra-Etchegaray, Nicole Salès, Gerald Wells, Paul Brown, Jean-Philippe Deslys

 

Summary The uncertain extent of human exposure to bovine spongiform encephalopathy (BSE)--which can lead to variant Creutzfeldt-Jakob disease (vCJD)--is compounded by incomplete knowledge about the efficiency of oral infection and the magnitude of any bovine-to-human biological barrier to transmission. We therefore investigated oral transmission of BSE to non-human primates. We gave two macaques a 5 g oral dose of brain homogenate from a BSE-infected cow. One macaque developed vCJD-like neurological disease 60 months after exposure, whereas the other remained free of disease at 76 months. On the basis of these findings and data from other studies, we made a preliminary estimate of the food exposure risk for man, which provides additional assurance that existing public health measures can prevent transmission of BSE to man.

Experimental BSE Infection of Non-human Primates: Efficacy of the Oral Route

Background:

 

In 2001, a study was initiated in primates to assess the risk for humans to contract BSE through contaminated food. For this purpose, BSE brain was titrated in cynomolgus monkeys.

 

Aims:

 

The primary objective is the determination of the minimal infectious dose (MID50) for oral exposure to BSE in a simian model, and, by in doing this, to assess the risk for humans. Secondly, we aimed at examining the course of the disease to identify possible biomarkers.

 

Methods:

 

Groups with six monkeys each were orally dosed with lowering amounts of BSE brain: 16g, 5g, 0.5g, 0.05g, and 0.005g. In a second titration study, animals were intracerebrally (i.c.) dosed (50, 5, 0.5, 0.05, and 0.005 mg).

 

Results:

 

In an ongoing study, a considerable number of high-dosed macaques already developed simian vCJD upon oral or intracerebral exposure or are at the onset of the clinical phase. However, there are differences in the clinical course between orally and intracerebrally infected animals that may influence the detection of biomarkers.

 

Conclusions:

 

Simian vCJD can be easily triggered in cynomolgus monkeys on the oral route using less than 5 g BSE brain homogenate. The difference in the incubation period between 5 g oral and 5 mg i.c. is only 1 year (5 years versus 4 years). However, there are rapid progressors among orally dosed monkeys that develop simian v CJD as fast as intracerebrally inoculated animals.

 

The work referenced was performed in partial fulfillment of the study "BSE in primates" supported by the EU (QLK1-2002-01096).

 


 

Calves were challenged by mouth with homogenised brain from confirmed cases of BSE. Some received 300g (3 doses of 100g), some 100g, 10g or 1g. They were then left to develop BSE, but were not subjected to the normal stresses that they might have encountered in a dairy herd. Animals in all four groups developed BSE. There has been a considerable spread of incubation period in some of the groups, but it appears as if those in the 1 and 10g challenge groups most closely fit the picture of incubation periods seen in the epidemic. Experiments in progress indicate that oral infection can occur in some animals with doses as low as 0.01g and 0.001g. .........

 


 

It is clear that the designing scientists must also have shared Mr Bradley's surprise at the results because all the dose levels right down to 1 gram triggered infection.

 


 

6. It also appears to me that Mr Bradley's answer (that it would take less than say 100 grams) was probably given with the benefit of hindsight; particularly if one considers that later in the same answer Mr Bradley expresses his surprise that it could take as little of 1 gram of brain to cause BSE by the oral route within the same species. This information did not become available until the "attack rate" experiment had been completed in 1995/96. This was a titration experiment designed to ascertain the infective dose. A range of dosages was used to ensure that the actual result was within both a lower and an upper limit within the study and the designing scientists would not have expected all the dose levels to trigger infection. The dose ranges chosen by the most informed scientists at that time ranged from 1 gram to three times one hundred grams. It is clear that the designing scientists must have also shared Mr Bradley's surprise at the results because all the dose levels right down to 1 gram triggered infection.

 


 


 


 


 

FDA ANNOUNCES TEST RESULTS FROM TEXAS FEED LOT

 

Today the Food and Drug Administration announced the results of tests taken on feed used at a Texas feedlot that was suspected of containing meat and bone meal from other domestic cattle -- a violation of FDA's 1997 prohibition on using ruminant material in feed for other ruminants. Results indicate that a very low level of prohibited material was found in the feed fed to cattle.

 

FDA has determined that each animal could have consumed, at most and in total, five-and-one-half grams - approximately a quarter ounce -- of prohibited material. These animals weigh approximately 600 pounds.

 

It is important to note that the prohibited material was domestic in origin (therefore not likely to contain infected material because there is no evidence of BSE in U.S. cattle), fed at a very low level, and fed only once. The potential risk of BSE to such cattle is therefore exceedingly low, even if the feed were contaminated.

 

According to Dr. Bernard Schwetz, FDA's Acting Principal Deputy Commissioner, "The challenge to regulators and industry is to keep this disease out of the United States. One important defense is to prohibit the use of any ruminant animal materials in feed for other ruminant animals. Combined with other steps, like U.S. Department of Agriculture's (USDA) ban on the importation of live ruminant animals from affected countries, these steps represent a series of protections, to keep American cattle free of BSE."

 

Despite this negligible risk, Purina Mills, Inc., is nonetheless announcing that it is voluntarily purchasing all 1,222 of the animals held in Texas and mistakenly fed the animal feed containing the prohibited material. Therefore, meat from those animals will not enter the human food supply. FDA believes any cattle that did not consume feed containing the prohibited material are unaffected by this incident, and should be handled in the beef supply clearance process as usual. ...

CHAIR—Welcome. Would you like to make an opening statement?

 

Mr Bellinger—Thank you. The ABA stands by its submission, which we made on 14

 

December last year, that the decision made by the government to allow the importation of beef from BSE affected countries is politically based, not science based. During this hearing we will bring forward compelling new evidence to back up this statement. When I returned to my property after the December hearing I received a note from an American citizen. I will read a small excerpt from the mail he sent me in order to reinforce the dangers of allowing the importation of beef from BSE affected countries. I have done a number of press releases on this topic, and this fellow has obviously picked my details up from the internet. His name is Terry Singeltary and he is from Bacliff, Texas. He states, and rightfully so:

We have shown that cattle-adapted TME is the third cattle prion strain (joining classical and L-type BSE) to be transmissible both to non-human primates and transgenic mice overexpressing human PrP. However, the successful transmission of raccoon TME to primate, inducing a disease with similar features as cattle TME, extends this notion to TME-related strains independent of host origin. Pathological, biochemical and bioassay investigations converged to demonstrate the similarity between cattle-adapted TME and L-BSE.

 


 

O.05: Transmission of prions to primates after extended silent incubation periods: Implications for BSE and scrapie risk assessment in human populations

Prion diseases (PD) are the unique neurodegenerative proteinopathies reputed to be transmissible under field conditions since decades. The transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that an animal PD might be zoonotic under appropriate conditions. Contrarily, in the absence of obvious (epidemiological or experimental) elements supporting a transmission or genetic predispositions, PD, like the other proteinopathies, are reputed to occur spontaneously (atpical animal prion strains, sporadic CJD summing 80% of human prion cases). Non-human primate models provided the first evidences supporting the transmissibiity of human prion strains and the zoonotic potential of BSE. Among them, cynomolgus macaques brought major information for BSE risk assessment for human health (Chen, 2014), according to their phylogenetic proximity to humans and extended lifetime. We used this model to assess the zoonotic potential of other animal PD from bovine, ovine and cervid origins even after very long silent incubation periods. *** We recently observed the direct transmission of a natural classical scrapie isolate to macaque after a 10-year silent incubation period, ***with features similar to some reported for human cases of sporadic CJD, albeit requiring fourfold longe incubation than BSE. Scrapie, as recently evoked in humanized mice (Cassard, 2014), ***is the third potentially zoonotic PD (with BSE and L-type BSE), ***thus questioning the origin of human sporadic cases. We will present an updated panorama of our different transmission studies and discuss the implications of such extended incubation periods on risk assessment of animal PD for human health.

***Moreover, L-BSE has been transmitted more easily to transgenic mice overexpressing a human PrP [13,14] or to primates [15,16] than C-BSE.

 

***It has been suggested that some sporadic CJD subtypes in humans may result from an exposure to the L-BSE agent.

 

*** Lending support to this hypothesis, pathological and biochemical similarities have been observed between L-BSE and an sCJD subtype (MV genotype at codon 129 of PRNP) [17], and between L-BSE infected non-human primate and another sCJD subtype (MM genotype) [15].

EFSA Journal 2011 The European Response to BSE: A Success Story

 

snip...

 

EFSA and the European Centre for Disease Prevention and Control (ECDC) recently delivered a scientific opinion on any possible epidemiological or molecular association between TSEs in animals and humans (EFSA Panel on Biological Hazards (BIOHAZ) and ECDC, 2011). This opinion confirmed Classical BSE prions as the only TSE agents demonstrated to be zoonotic so far

 

*** but the possibility that a small proportion of human cases so far classified as "sporadic" CJD are of zoonotic origin could not be excluded.

 

*** Moreover, transmission experiments to non-human primates suggest that some TSE agents in addition to Classical BSE prions in cattle (namely L-type Atypical BSE, Classical BSE in sheep, transmissible mink encephalopathy (TME) and chronic wasting disease (CWD) agents) might have zoonotic potential.

Seven main threats for the future linked to prions

 

First threat

 

The TSE road map defining the evolution of European policy for protection against prion diseases is based on a certain numbers of hypotheses some of which may turn out to be erroneous. In particular, a form of BSE (called atypical Bovine Spongiform Encephalopathy), recently identified by systematic testing in aged cattle without clinical signs, may be the origin of classical BSE and thus potentially constitute a reservoir, which may be impossible to eradicate if a sporadic origin is confirmed.

 

*** Also, a link is suspected between atypical BSE and some apparently sporadic cases of Creutzfeldt-Jakob disease in humans.

 

*** These atypical BSE cases constitute an unforeseen first threat that could sharply modify the European approach to prion diseases.

 

Second threat

Dear Terry,

 

I have been asked by Professor Collinge to respond to your request. I am a Senior Scientist in the MRC Prion Unit and the lead author on the paper. I have attached a pdf copy of the paper for your attention.

 

Thank you for your interest in the paper.

 

In respect of your first question, the simple answer is, ***yes. As you will find in the paper, we have managed to associate the alternate phenotype to type 2 PrPSc, the commonest sporadic CJD. It is too early to be able to claim any further sub-classification in respect of Heidenhain variant CJD or Vicky Rimmer's version. It will take further studies, which are on-going, to establish if there are sub-types to our initial finding which we are now reporting. The main point of the paper is that, as well as leading to the expected new variant CJD phenotype, BSE transmission to the 129-methionine genotype can lead to an alternate phenotype which is indistinguishable from type 2 PrPSc.

 

I hope reading the paper will enlighten you more on the subject. If I can be of any further assistance please to not hesitate to ask. Best wishes.

 

Emmanuel Asante

P.86: Estimating the risk of transmission of BSE and scrapie to ruminants and humans by protein misfolding cyclic amplification

 

Morikazu Imamura, Naoko Tabeta, Yoshifumi Iwamaru, and Yuichi Murayama National Institute of Animal Health; Tsukuba, Japan

 

To assess the risk of the transmission of ruminant prions to ruminants and humans at the molecular level, we investigated the ability of abnormal prion protein (PrPSc) of typical and atypical BSEs (L-type and H-type) and typical scrapie to convert normal prion protein (PrPC) from bovine, ovine, and human to proteinase K-resistant PrPSc-like form (PrPres) using serial protein misfolding cyclic amplification (PMCA).

 

Six rounds of serial PMCA was performed using 10% brain homogenates from transgenic mice expressing bovine, ovine or human PrPC in combination with PrPSc seed from typical and atypical BSE- or typical scrapie-infected brain homogenates from native host species. In the conventional PMCA, the conversion of PrPC to PrPres was observed only when the species of PrPC source and PrPSc seed matched. However, in the PMCA with supplements (digitonin, synthetic polyA and heparin), both bovine and ovine PrPC were converted by PrPSc from all tested prion strains. On the other hand, human PrPC was converted by PrPSc from typical and H-type BSE in this PMCA condition.

 

Although these results were not compatible with the previous reports describing the lack of transmissibility of H-type BSE to ovine and human transgenic mice, ***our findings suggest that possible transmission risk of H-type BSE to sheep and human. Bioassay will be required to determine whether the PMCA products are infectious to these animals.

European red deer (Cervus elaphus elaphus) are susceptible to Bovine Spongiform Encephalopathy BSE by Oral Alimentary route

 


 

I strenuously once again urge the FDA and its industry constituents, to make it MANDATORY that all ruminant feed be banned to all ruminants, and this should include all cervids as soon as possible for the following reasons...

 

======

 

In the USA, under the Food and Drug Administrations BSE Feed Regulation (21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin) from deer and elk is prohibited for use in feed for ruminant animals. With regards to feed for non-ruminant animals, under FDA law, CWD positive deer may not be used for any animal feed or feed ingredients. For elk and deer considered at high risk for CWD, the FDA recommends that these animals do not enter the animal feed system.

 

***However, this recommendation is guidance and not a requirement by law.

Two novel prion strains, referred to as BSE-L and BSE-H, have been recognized in bovines through active prion surveillance programs, both being distinct from the epizootic, ‘classical’, BSE strain (C-BSE). Both H and L-types have been detected worldwide as rare cases occurring in aged animals. Like C-BSE prions, H- and L-types prions can propagate with relative ease in foreign species or in transgenic mouse lines expressing heterologous PrP sequences. A prion exhibiting biological properties similar to C-BSE agent sometimes emerged from these cross-species transmissions. Previously, L-type prions were shown to transmit to transgenic mice expressing human PrP with methionine at codon 129 with higher efficacy than C-BSE prions. Here, we examined whether L-type prions propagate without any apparent transmission barrier in these mice and whether such ‘humanised’ L-type prions share biological properties with CJD prions. L-type prions and a panel of human CJD cases with various genotypes at codon 129 and electrophoretic PrPres signatures were serially transmitted by intracerebral route to human PrP mice. The biological phenotypes induced by these agents were compared by all the standard methods currently used to distinguish between prion strains. At each passage, L-type prions were also transmitted back to bovine PrP mice to assess whether the agent has evolved upon passaging on the human PrP sequence. L-type prions transmitted to human PrP mice at 100% attack rate, without notable alteration in the mean incubation times over 5 passages. At each passage, ‘humanized’ L-type prions were able to transmit back to bovine PrP transgenic mice without apparent transmission barrier, as based on the survival time and the restoration of a L-type BSE phenotype. Comparison of mean incubation times on primary and subsequent passages in human PrP mice showed no overlap between L-type and sporadic CJD agents. While the electrophoretic signature and regional distribution of PrPres in L-type diseased mouse brains resembled that seen after transmission of MM2 CJD strain type, both agents exhibited distinct resistance of the associated PrPres molecules to protease denaturation.

 

In summary, L-type prions can be passaged on the human PrP sequence without any obvious transmission barrier. The phenotype obtained differs from the classical CJD prion types known so far. Careful extrapolation would suggest that the zoonotic transmission of this agent could establish a new prion disease type in humans.

In this way, policies to protect Canadians were often delayed and incomplete, in a manner disturbingly reminiscent of Britain’s failed management of BSE. Despite assurances to the contrary, it is premature to conclude that BSE (and with it the risk of variant Creutzfeldt-Jakob disease) is a thing of Canada’s past: BSE remains very much an issue in Canada’s present. <<<

 Detection and Discrimination of Classical and Atypical L-Type BSE Strains by RT-QuIC

 

Description of Technology: Statutory surveillance of bovine spongiform encephalopathy (BSE) indicates that cattle are susceptible to both classical (C–BSE) and atypical forms of BSE. Atypical forms of BSE appear to be sporadic and thus may never be eradicated. A major challenge is the lack of sufficiently practical and sensitive tests for routine BSE detection and strain discrimination. The RT-QuIC test, which is based on prion-seeded fibrillization of recombinant prion protein (rPrPSen), is known to be highly specific and sensitive for detection of multiple human and animal prion diseases, but not BSE. This application claims methods for distinguishing whether a sheep, cow or goat has atypical L-bovine spongiform encephalopathy prion or classical bovine spongiform encephalopathy.

 

Potential Commercial Applications

 

• Detection and distinguishing of both BSE forms

 

• Rapid detection and discrimination of BSE forms Competitive Advantages

 

• Orders of magnitude more sensitive than ELISA tests

 

• Eliminates need for multi-phase analyses of samples

 

• Can be applied to large scale testing of multiple samples Development Stage

 

• In vitro data available

 

• In vivo data available (animal)

>>> Atypical forms of BSE appear to be sporadic and thus may never be eradicated...

 

LMAO...atypical forms of BSE have never ever been proven to be of a spontaneous nature, as with sporadic CJD, a case of wishful thinking, and they also may never be eradicated too, because of industry. call it spontaneous if you must $$$

 

FRANCE HAVE AN EPIDEMIC OF SPONTANEOUS ATYPICAL BSE ‘’LOL’’

 

spontaneous atypical BSE ???

 

if that's the case, then France is having one hell of an epidemic of atypical BSE, probably why they stopped testing for BSE, problem solved $$$

 

As of December 2011, around 60 atypical BSE cases have currently been reported in 13 countries, *** with over one third in France.

 


 

so 20 cases of atypical BSE in France, compared to the remaining 40 cases in the remaining 12 Countries, divided by the remaining 12 Countries, about 3+ cases per country, besides Frances 20 cases. you cannot explain this away with any spontaneous BSe. ...TSS

*** We describe the transmission of spongiform encephalopathy in a non-human primate inoculated 10 years earlier with a strain of sheep c-scrapie. Because of this extended incubation period in a facility in which other prion diseases are under study, we are obliged to consider two alternative possibilities that might explain its occurrence. We first considered the possibility of a sporadic origin (like CJD in humans). Such an event is extremely improbable because the inoculated animal was 14 years old when the clinical signs appeared, i.e. about 40% through the expected natural lifetime of this species, compared to a peak age incidence of 60–65 years in human sporadic CJD, or about 80% through their expected lifetimes.

 

***Moreover, sporadic disease has never been observed in breeding colonies or primate research laboratories, most notably among hundreds of animals over several decades of study at the National Institutes of Health25, and in nearly twenty older animals continuously housed in our own facility.***

***P.170: Potential detection of oral transmission of H type atypical BSE in cattle using in vitro conversion

 

Sandor Dudas, John G Gray, Renee Clark, and Stefanie Czub Canadian Food Inspection Agency; Lethbridge, AB Canada

 

Keywords: Atypical BSE, oral transmission, RT-QuIC

 

The detection of bovine spongiform encephalopathy (BSE) has had a significant negative impact on the cattle industry worldwide. In response, governments took actions to prevent transmission and additional threats to animal health and food safety. While these measures seem to be effective for controlling classical BSE, the more recently discovered atypical BSE has presented a new challenge. To generate data for risk assessment and control measures, we have challenged cattle orally with atypical BSE to determine transmissibility and mis-folded prion (PrPSc) tissue distribution. Upon presentation of clinical symptoms, animals were euthanized and tested for characteristic histopathological changes as well as PrPSc deposition.

 

The H-type challenged animal displayed vacuolation exclusively in rostral brain areas but the L-type challenged animal showed no evidence thereof. To our surprise, neither of the animals euthanized, which were displaying clinical signs indicative of BSE, showed conclusive mis-folded prion accumulation in the brain or gut using standard molecular or immunohistochemical assays. To confirm presence or absence of prion infectivity, we employed an optimized real-time quaking induced conversion (RT-QuIC) assay developed at the Rocky Mountain Laboratory, Hamilton, USA.

 

Detection of PrPSc was unsuccessful for brain samples tests from the orally inoculated L type animal using the RT-QuIC. It is possible that these negative results were related to the tissue sampling locations or that type specific optimization is needed to detect PrPSc in this animal. We were however able to consistently detect the presence of mis-folded prions in the brain of the H-type inoculated animal. Considering the negative and inconclusive results with other PrPSc detection methods, positive results using the optimized RT-QuIC suggests the method is extremely sensitive for H-type BSE detection. This may be evidence of the first successful oral transmission of H type atypical BSE in cattle and additional investigation of samples from these animals are ongoing.

 

P.126: Successful transmission of chronic wasting disease (CWD) into mice over-expressing bovine prion protein (TgSB3985)

Keywords: chronic wasting disease, transmission, transgenic mouse, bovine prion protein

 

Background. CWD is a disease affecting wild and farmraised cervids in North America. Epidemiological studies provide no evidence of CWD transmission to humans. Multiple attempts have failed to infect transgenic mice expressing human PRNP gene with CWD. The extremely low efficiency of PrPCWD to convert normal human PrPC in vitro provides additional evidence that transmission of CWD to humans cannot be easily achieved. However, a concern about the risk of CWD transmission to humans still exists. This study aimed to establish and characterize an experimental model of CWD in TgSB3985 mice with the following attempt of transmission to TgHu mice.

 

Materials and Methods. TgSB3985 mice and wild-type FVB/ NCrl mice were intracranially injected with 1% brain homogenate from a CWD-infected Tga20 mouse (CWD/Tga20). TgSB3985 and TgRM (over-expressing human PrP) were similarly injected with 5% brain homogenates from CWD-infected white-tailed deer (CWD/WTD) or elk (CWD/Elk). Animals were observed for clinical signs of neurological disease and were euthanized when moribund. Brains and spleens were removed from all mice for PrPCWD detection by Western blotting (WB). A histological analysis of brains from selected animals was performed: brains were scored for the severity of spongiform change, astrogliosis, and PrPCWD deposition in ten brain regions.

 

Results. Clinical presentation was consistent with TSE. More than 90% of TgSB3985 and wild-type mice infected with CWD/Tga20, tested positive for PrPres in the brain but only mice in the latter group carried PrPCWD in their spleens. We found evidence for co-existence or divergence of two CWD/ Tga20 strains based on biochemical and histological profiles. In TgSB3985 mice infected with CWD-elk or CWD-WTD, no animals tested positive for PrPCWD in the brain or in the spleen by WB. However, on neuropathological examination we found presence of amyloid plaques that stained positive for PrPCWD in three CWD/WTD- and two CWD/Elk-infected TgSB3985 mice. The neuropathologic profiles in CWD/WTD- and CWD/Elkinfected mice were similar but unique as compared to profiles of BSE, BSE-H or CWD/Tg20 agents propagated in TgSB3985 mice. None of CWD-infected TgRM mice tested positive for PrPCWD by WB or by immunohistochemical detection.

 

Conclusions. To our knowledge, this is the first established experimental model of CWD in TgSB3985. We found evidence for co-existence or divergence of two CWD strains adapted to Tga20 mice and their replication in TgSB3985 mice. Finally, we observed phenotypic differences between cervid-derived CWD and CWD/Tg20 strains upon propagation in TgSB3985 mice. Further studies are underway to characterize these strains.

 

P.150: Zoonotic potential of L-type BSE prions: A new prion disease in humans?

December last year, that the decision made by the government to allow the importation of beef from BSE affected countries is politically based, not science based. During this hearing we will bring forward compelling new evidence to back up this statement. When I returned to my property after the December hearing I received a note from an American citizen. I will read a small excerpt from the mail he sent me in order to reinforce the dangers of allowing the importation of beef from BSE affected countries. I have done a number of press releases on this topic, and this fellow has obviously picked my details up from the internet. His name is Terry Singeltary and he is from Bacliff, Texas. He states, and rightfully so:

We have shown that cattle-adapted TME is the third cattle prion strain (joining classical and L-type BSE) to be transmissible both to non-human primates and transgenic mice overexpressing human PrP. However, the successful transmission of raccoon TME to primate, inducing a disease with similar features as cattle TME, extends this notion to TME-related strains independent of host origin. Pathological, biochemical and bioassay investigations converged to demonstrate the similarity between cattle-adapted TME and L-BSE.

 


 

CJD toll among farmers `too high for mere chance'

 

August 15, 1997

 

PA News

 

John von Radowitz and Andrew Woodcock Microbiologist Richard Lacey, billed in this story as the first to suggest a link between CJD and BSE seven years ago, was cited in this story as saying that the number of cattle farmers falling victim to Creutzfeld-Jakob Disease is much too high to be mere chance, adding that, "Where the CJD Surveillance Unit come unstuck is in trying to explain what happened to these six farmers. This is just too many to have occurred by chance. Unfortunately they don't want to consider the possibility that these farmers in this country and other countries were infected by cattle before BSE developed." The story notes that professor Lacey believes sporadic CJD itself originates from a cattle infection - possibly a precursor to BSE that has not yet been detected, adding that,

 

"For years I have suggested that the cause is a rare disease in cattle world wide. Both BSE and the new variant CJD are a new and different disease. What has probably happened is that BSE is a variant of the old type of disease, which could have been missed because it's symptom free. It would explain why such an unusually high number of dairy farmers are being affected by CJD both here and abroad." He also said that cases of sporadic CJD had been recorded as far back as the 1920s. Professor Lacey went on to add that he thought the new variant pattern was alarming, adding, "It's rising, and that is a concern. Unfortunately we can't predict the scale of the problem. If the disease doubled each year up to the year 2020 you'd have hundreds of thousands of cases."

 


 

.195 Among occupational groups exposed to BSE, farmers remain unusual in having such an excess over the incidence of CJD for the population as a whole. No cases of CJD have been reported amount veterinarians exposed to BSE. Four people in the meat industry (butchers, abattoirs, rendering plants, etc) have been reported to have vCJD.386 The present evidence has been accepted by some as reassuring in that such occupations may not pose as serious a risk as might have been expected.

2. Over a 5 year period, which is the time period on which the advice from Professor Smith and Dr. Gore was based, and assuming a population of 120,000 dairy farm workers, and an annual incidence of 1 per million cases of CJD in the general population, a DAIRY FARM WORKER IS 5 TIMES MORE LIKELY THAN an individual in the general population to develop CJD. Using the actual current annual incidence of CJD in the UK of 0.7 per million, this figure becomes 7.5 TIMES.

 

3. You will recall that the advice provided by Professor Smith in 1993 and by Dr. Gore this month used the sub-population of dairy farm workers who had had a case of BSE on their farms - 63,000, which is approximately half the number of dairy farm workers - as a denominator. If the above sums are repeated using this denominator population, taking an annual incidence in the general population of 1 per million the observed rate in this sub-population is 10 TIMES, and taking an annual incidence of 0.7 per million, IT IS 15 TIMES (THE ''WORST CASE'' SCENARIO) than that in the general population...

Zoonotic Potential of CWD Prions

Chronic wasting disease (CWD) is a widespread and expanding prion disease in free-ranging and captive cervid species in North America. The zoonotic potential of CWD prions is a serious public health concern. Current literature generated with in vitro methods and in vivo animal models (transgenic mice, macaques and squirrel monkeys) reports conflicting results. The susceptibility of human CNS and peripheral organs to CWD prions remains largely unresolved. In our earlier bioassay experiments using several humanized transgenic mouse lines, we detected protease-resistant PrPSc in the spleen of two out of 140 mice that were intracerebrally inoculated with natural CWD isolates, but PrPSc was not detected in the brain of the same mice. Secondary passages with such PrPSc-positive CWD-inoculated humanized mouse spleen tissues led to efficient prion transmission with clear clinical and pathological signs in both humanized and cervidized transgenic mice. Furthermore, a recent bioassay with natural CWD isolates in a new humanized transgenic mouse line led to clinical prion infection in 2 out of 20 mice. These results indicate that the CWD prion has the potential to infect human CNS and peripheral lymphoid tissues and that there might be asymptomatic human carriers of CWD infection.

P.105: RT-QuIC models trans-species prion transmission

 

Kristen Davenport, Davin Henderson, Candace Mathiason, and Edward Hoover Prion Research Center; Colorado State University; Fort Collins, CO USA

 

The propensity for trans-species prion transmission is related to the structural characteristics of the enciphering and heterologous PrP, but the exact mechanism remains mostly mysterious. Studies of the effects of primary or tertiary prion protein structures on trans-species prion transmission have relied primarily upon animal bioassays, making the influence of prion protein structure vs. host co-factors (e.g. cellular constituents, trafficking, and innate immune interactions) difficult to dissect. As an alternative strategy, we used real-time quakinginduced conversion (RT-QuIC) to investigate trans-species prion conversion.

 

To assess trans-species conversion in the RT-QuIC system, we compared chronic wasting disease (CWD) and bovine spongiform encephalopathy (BSE) prions, as well as feline CWD (fCWD) and feline spongiform encephalopathy (FSE). Each prion was seeded into each host recombinant PrP (full-length rPrP of white-tailed deer, bovine or feline). We demonstrated that fCWD is a more efficient seed for feline rPrP than for white-tailed deer rPrP, which suggests adaptation to the new host.

 

Conversely, FSE maintained sufficient BSE characteristics to more efficiently convert bovine rPrP than feline rPrP. Additionally, human rPrP was competent for conversion by CWD and fCWD. ***This insinuates that, at the level of protein:protein interactions, the barrier preventing transmission of CWD to humans is less robust than previously estimated.

***In addition, non-human primates are specifically susceptible for atypical BSE as demonstrated by an approximately 50% shortened incubation time for L-type BSE as compared to C-type. Considering the current scientific information available, it cannot be assumed that these different BSE types pose the same human health risks as C-type BSE or that these risks are mitigated by the same protective measures.

O.05: Transmission of prions to primates after extended silent incubation periods: Implications for BSE and scrapie risk assessment in human populations

 

Emmanuel Comoy, Jacqueline Mikol, Val erie Durand, Sophie Luccantoni, Evelyne Correia, Nathalie Lescoutra, Capucine Dehen, and Jean-Philippe Deslys Atomic Energy Commission; Fontenay-aux-Roses, France

 

Prion diseases (PD) are the unique neurodegenerative proteinopathies reputed to be transmissible under field conditions since decades. The transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that an animal PD might be zoonotic under appropriate conditions. Contrarily, in the absence of obvious (epidemiological or experimental) elements supporting a transmission or genetic predispositions, PD, like the other proteinopathies, are reputed to occur spontaneously (atpical animal prion strains, sporadic CJD summing 80% of human prion cases). Non-human primate models provided the first evidences supporting the transmissibiity of human prion strains and the zoonotic potential of BSE. Among them, cynomolgus macaques brought major information for BSE risk assessment for human health (Chen, 2014), according to their phylogenetic proximity to humans and extended lifetime. We used this model to assess the zoonotic potential of other animal PD from bovine, ovine and cervid origins even after very long silent incubation periods. ***We recently observed the direct transmission of a natural classical scrapie isolate to macaque after a 10-year silent incubation period, with features similar to some reported for human cases of sporadic CJD, albeit requiring fourfold longe incubation than BSE. ***Scrapie, as recently evoked in humanized mice (Cassard, 2014), is the third potentially zoonotic PD (with BSE and L-type BSE), ***thus questioning the origin of human sporadic cases. We will present an updated panorama of our different transmission studies and discuss the implications of such extended incubation periods on risk assessment of animal PD for human health.

Dear Terry,

 

I have been asked by Professor Collinge to respond to your request. I am a Senior Scientist in the MRC Prion Unit and the lead author on the paper. I have attached a pdf copy of the paper for your attention.

 

Thank you for your interest in the paper.

 

In respect of your first question, the simple answer is, ***yes. As you will find in the paper, we have managed to associate the alternate phenotype to type 2 PrPSc, the commonest sporadic CJD. It is too early to be able to claim any further sub-classification in respect of Heidenhain variant CJD or Vicky Rimmer's version. It will take further studies, which are on-going, to establish if there are sub-types to our initial finding which we are now reporting. The main point of the paper is that, as well as leading to the expected new variant CJD phenotype, BSE transmission to the 129-methionine genotype can lead to an alternate phenotype which is indistinguishable from type 2 PrPSc.

 

I hope reading the paper will enlighten you more on the subject. If I can be of any further assistance please to not hesitate to ask. Best wishes.

 

Emmanuel Asante

P.86: Estimating the risk of transmission of BSE and scrapie to ruminants and humans by protein misfolding cyclic amplification

 

Morikazu Imamura, Naoko Tabeta, Yoshifumi Iwamaru, and Yuichi Murayama National Institute of Animal Health; Tsukuba, Japan

 

To assess the risk of the transmission of ruminant prions to ruminants and humans at the molecular level, we investigated the ability of abnormal prion protein (PrPSc) of typical and atypical BSEs (L-type and H-type) and typical scrapie to convert normal prion protein (PrPC) from bovine, ovine, and human to proteinase K-resistant PrPSc-like form (PrPres) using serial protein misfolding cyclic amplification (PMCA).

 

Six rounds of serial PMCA was performed using 10% brain homogenates from transgenic mice expressing bovine, ovine or human PrPC in combination with PrPSc seed from typical and atypical BSE- or typical scrapie-infected brain homogenates from native host species. In the conventional PMCA, the conversion of PrPC to PrPres was observed only when the species of PrPC source and PrPSc seed matched. However, in the PMCA with supplements (digitonin, synthetic polyA and heparin), both bovine and ovine PrPC were converted by PrPSc from all tested prion strains. On the other hand, human PrPC was converted by PrPSc from typical and H-type BSE in this PMCA condition.

 

Although these results were not compatible with the previous reports describing the lack of transmissibility of H-type BSE to ovine and human transgenic mice, ***our findings suggest that possible transmission risk of H-type BSE to sheep and human. Bioassay will be required to determine whether the PMCA products are infectious to these animals.

An Arizona meat processing company and its owner pled guilty in February 2007 to charges of theft of Government funds, mail fraud, and wire fraud. The owner and his company defrauded the BSE Surveillance Program when they falsified BSE Surveillance Data Collection Forms and then submitted payment requests to USDA for the services. In addition to the targeted sample population (those cattle that were more than 30 months old or had other risk factors for BSE), the owner submitted to USDA, or caused to be submitted, BSE obex (brain stem) samples from healthy USDA-inspected cattle. As a result, the owner fraudulently received approximately $390,000. Sentencing is scheduled for May 2007.

Two novel prion strains, referred to as BSE-L and BSE-H, have been recognized in bovines through active prion surveillance programs, both being distinct from the epizootic, ‘classical’, BSE strain (C-BSE). Both H and L-types have been detected worldwide as rare cases occurring in aged animals. Like C-BSE prions, H- and L-types prions can propagate with relative ease in foreign species or in transgenic mouse lines expressing heterologous PrP sequences. A prion exhibiting biological properties similar to C-BSE agent sometimes emerged from these cross-species transmissions. Previously, L-type prions were shown to transmit to transgenic mice expressing human PrP with methionine at codon 129 with higher efficacy than C-BSE prions. Here, we examined whether L-type prions propagate without any apparent transmission barrier in these mice and whether such ‘humanised’ L-type prions share biological properties with CJD prions. L-type prions and a panel of human CJD cases with various genotypes at codon 129 and electrophoretic PrPres signatures were serially transmitted by intracerebral route to human PrP mice. The biological phenotypes induced by these agents were compared by all the standard methods currently used to distinguish between prion strains. At each passage, L-type prions were also transmitted back to bovine PrP mice to assess whether the agent has evolved upon passaging on the human PrP sequence. L-type prions transmitted to human PrP mice at 100% attack rate, without notable alteration in the mean incubation times over 5 passages. At each passage, ‘humanized’ L-type prions were able to transmit back to bovine PrP transgenic mice without apparent transmission barrier, as based on the survival time and the restoration of a L-type BSE phenotype. Comparison of mean incubation times on primary and subsequent passages in human PrP mice showed no overlap between L-type and sporadic CJD agents. While the electrophoretic signature and regional distribution of PrPres in L-type diseased mouse brains resembled that seen after transmission of MM2 CJD strain type, both agents exhibited distinct resistance of the associated PrPres molecules to protease denaturation.

 

In summary, L-type prions can be passaged on the human PrP sequence without any obvious transmission barrier. The phenotype obtained differs from the classical CJD prion types known so far. Careful extrapolation would suggest that the zoonotic transmission of this agent could establish a new prion disease type in humans.

*** As far as spontaneous cases, that is a very difficult issue.

 

***There is no evidence to prove that spontaneous BSE occurs in cattle; but here again it's an issue of proving a negative.

 

*** We do know that CJD, the human version of the disease, does occur spontaneously in humans at the rate of about 1 in 1 million.

 

*** We don't have enough data to definitively say that spontaneous cases of BSE in cattle occur or do not occur.

 

“Again, it's a very difficult situation to prove a negative.

 

“So a lot of research is ongoing. Certainly if we do come up with any positive samples in the course of this surveillance we will be looking at that question in evaluating those samples but no scientifically hard evidence to confirm or refute whether or not spontaneous cases of BSE occur.

What irks many scientists is the USDA?s April 25 statement that the rare disease is ?not generally associated with an animal consuming infected feed.?

 

The USDA?s conclusion is a ?gross oversimplification,? said Dr. Paul Brown, one of the world?s experts on this type of disease who retired recently from the National Institutes of Health.

 

"(The agency) has no foundation on which to base that statement.?

 

?We can?t say it?s not feed related,? agreed Dr. Linda Detwiler, an official with the USDA during the Clinton Administration now at Mississippi State.

 

In the May 1 email to me, USDA?s Cole backed off a bit. ?No one knows the origins of atypical cases of BSE,? she said

 

Few scientists would argue that the one California cow which never was headed to the U.S. food supply represents a health hazard.

 

But many maintain that the current surveillance is insufficient.

 

Dr. Kurt Giles, an expert in neurogenerative diseases now at the University of California, San Francisco, was at Oxford during the British outbreak.

 

He told me USDA?s assurances about safety today remind him of British statements during the 1980s.

 

?It is so reminiscent of that absolute certainty,? he said.

THE USDA JUNE 2004 ENHANCED BSE SURVEILLANCE PROGRAM WAS TERRIBLY FLAWED ;

 

CDC DR. PAUL BROWN TSE EXPERT COMMENTS 2006

 

In an article today for United Press International, science reporter Steve Mitchell writes:

 

Analysis: What that mad cow means

 

By STEVE MITCHELL UPI Senior Medical Correspondent

 

WASHINGTON, March 15 (UPI) -- The U.S. Department of Agriculture was quick to assure the public earlier this week that the third case of mad cow disease did not pose a risk to them, but what federal officials have not acknowledged is that this latest case indicates the deadly disease has been circulating in U.S. herds for at least a decade.

 

The second case, which was detected last year in a Texas cow and which USDA officials were reluctant to verify, was approximately 12 years old.

 

These two cases (the latest was detected in an Alabama cow) present a picture of the disease having been here for 10 years or so, since it is thought that cows usually contract the disease from contaminated feed they consume as calves. The concern is that humans can contract a fatal, incurable, brain-wasting illness from consuming beef products contaminated with the mad cow pathogen.

 

"The fact the Texas cow showed up fairly clearly implied the existence of other undetected cases," Dr. Paul Brown, former medical director of the National Institutes of Health's Laboratory for Central Nervous System Studies and an expert on mad cow-like diseases, told United Press International. "The question was, 'How many?' and we still can't answer that."

 

Brown, who is preparing a scientific paper based on the latest two mad cow cases to estimate the maximum number of infected cows that occurred in the United States, said he has "absolutely no confidence in USDA tests before one year ago" because of the agency's reluctance to retest the Texas cow that initially tested positive.

 

USDA officials finally retested the cow and confirmed it was infected seven months later, but only at the insistence of the agency's inspector general.

 

"Everything they did on the Texas cow makes everything they did before 2005 suspect," Brown said.

 

SNIP...

 

UPI requested detailed records about animals tested under the USDA's surveillance plan via the Freedom of Information Act in May 2004 but nearly two years later has not received any corresponding documents from the agency, despite a federal law requiring agencies to comply within 30 days. This leaves open the question of whether the USDA is withholding the information, does not have the information or is so haphazardly organized that it cannot locate it.

 

SNIP...

 

Markus Moser, a molecular biologist and chief executive officer of Prionics, a Swiss firm that manufactures BSE test kits, told UPI one concern is that if people are infected, the mad cow pathogen could become "humanized" or more easily transmitted from person to person.

 

"Transmission would be much easier, through all kinds of medical procedures" and even through the blood supply, Moser said.
