A CLOSER LOOK: BIOTECH ANIMALS
Genetically engineered animals and the FDA Are genetically engineered fish and meat coming soon? We examine the Food and Drug Administration's regulations.
By Jill U. Adams January 26, 2009
Fast-growing salmon. Pork containing heart-healthy omega-3 fatty acids. These are two examples of products you might see in your local supermarket soon -- animals developed not through conventional breeding but through genetic engineering.
On Jan. 15, the U.S. Food and Drug Administration decided how it will regulate genetically engineered animals, for the first time paving the way for such animals or their products to be sold as food and medicine. The agency has decided to categorize genetically engineered farm animals, also called transgenic animals, as an "animal drug." They will be held to the same requirements already existing for conventionally bred animals treated with hormones or antibiotics. (In the case of transgenic animals, the "drug" is a snippet of DNA.) Products derived from them or containing them as an ingredient will not necessarily require labeling.
A wide range of interested parties, including companies developing genetically engineered animals and consumer protection groups, are generally comfortable with the FDA decision. And yet, consumer acceptance of transgenic animals, particularly as food products, is still an unknown.
American consumers have been eating food from genetically engineered crops, such as corn, soybeans and canola, for a decade. However, transgenic animals have not been sold, pending the FDA deliberations on how to regulate them.
Why would someone want to genetically engineer animals?
Genetic engineering is a high-tech way to "breed" desirable traits into livestock. The benefits might be for the producer, such as a disease-resistant cow or an easy-to-raise salmon. It might be for the environment -- pigs that produce milder manure, for example -- or for the consumer, say, more nutritious meat.
The old-fashioned way of breeding farmed animals requires selecting offspring with desired traits over successive generations. Ron Stotish, chief executive of Aqua Bounty Technologies in Waltham, Mass., says the power of genetic engineering is that the same end is achieved in "one fell swoop." Transgenic animals also can be fitted with traits they probably would never develop naturally, as in the case of omega-3-producing pigs.
How is an animal genetically engineered?
An extra piece of genetic material (DNA) is inserted into the animal's genome at the earliest stages of development. Sometimes the method involves manipulating a fertilized egg that is then implanted into a surrogate mother; other times, it alters a cell from which an animal will be cloned. As the embryo grows, the DNA splice is replicated with the rest of the genetic material so that it ends up in every cell of the individual.
In fast-growing salmon developed by Aqua Bounty, the inserted gene is a salmon growth hormone, identical to the one the fish have naturally. The benefit comes from the precise placement of the added gene, which makes it active at times that the natural gene is not. "Normal salmon grow very, very slowly, and when it is cold they don't grow at all," Stotish says. "Our gene is active under a broader range of conditions and it allows the animals to grow." At 1 year old, a normal salmon might weigh 30 grams, but the transgenic fish weigh a kilogram, he says.
In pigs developed to contain omega-3 fatty acids, the added gene directs formation of an enzyme that converts naturally occurring omega-6 fatty acids to omega-3s. The gene is derived from tiny roundworms but is modified to make it more mammalian, says Randall Prather, co-director of the National Swine Resource and Research Center at the University of Missouri in Columbia, who developed these pigs.
Why did the FDA opt to regulate genetically engineered animals in this manner and what criteria are used to assess safety?
The FDA is responsible for food safety and already regulates genetically modified crops. By considering a DNA segment a drug, the agency will regulate transgenic animals in the same way it oversees dairy cows that receive growth hormone or beef cattle that get antibiotics, says FDA spokeswoman Siobhan DeLancey.
By using existing guidelines for so-called animal drugs, the FDA can put those products seeking approval into a process that is already up and running. "They have the staff and the process that allows them to look at this. They do it every day," says Stotish of Aqua Bounty, which has been seeking FDA approval for its fast-growing salmon for years.
Companies must show that their genetic manipulation is safe to the animal and that any food or animal-feed products derived from the animal are safe for the consumer and safe for the environment. Companies must also demonstrate that their claims about the gene-carried traits do occur.
Are there concerns beyond what the FDA can regulate?
Gregory Jaffe, who follows biotechnology for the consumer advocacy group Center for Science in the Public Interest, says the adopted guidelines are a good start "in the sense that the federal government has acknowledged that these animals are on the horizon and there needs to be oversight to ensure their safety."
But, he adds, genes are not the same as drugs. Drugs may have long-lasting effects on an individual, but they wouldn't get passed on to future generations. In the case of biotech animals, however, "you're altering the DNA of that animal, which gets carried on to its offspring." (Aqua Bounty says all the fish it markets will be sterile.)
Such lasting effects may have implications for preventing escape of the genes to natural populations, Jaffe says -- an issue that is beyond the FDA's expertise or authority.
Jaffe thinks the safety review should be more open and transparent. "Our regulatory processes for drugs" -- including animal drugs -- "are, on the whole, secret and done behind closed doors," he says. By law, the company controls what information is made public.
Other regulatory processes, such as those for pesticides at the Environmental Protection Agency, have been opened in past decades to invite public participation.
"Genetically engineered animals are highly controversial," Jaffe says. "I think that they [the FDA] need to have a transparent and participatory regulatory system -- where the public can review safety data and . . . expert scientists can provide comments to the agency."
Why did the FDA decide that food from genetically engineered animals doesn't have to be labeled?
The FDA labels food based on nutritional content, not manufacturing process, says the agency's DeLancey.
"So, if the food product is 'materially different' from a conventional product, then FDA can require that it be labeled. But the FDA doesn't require that a pork chop label specify whether it came from a pig produced through artificial insemination versus conventional breeding."
And similarly, now, if it came from genetically engineered animals. "We understand that consumers want transparency and labeling, but we are constrained by the regulations put in place by Congress," DeLancey says.
How will I know if the food I buy is from genetically engineered animals?
Pork from an omega-3 pig, should it gain approval, will be labeled because nutritional enhancement is a selling point -- and because the product is different from regular pork.
In other cases you may not know, although producers can voluntarily label their products. Researchers at the University of Guelph in Canada, who developed the so-called Enviropig with "greener" manure, say they intend to do so.
The U.S. Department of Agriculture has guidelines for labeling "natural meats," which would allow meat from non-transgenic animals to call attention to that fact.

TSS SUBMISSION TO ;
Docket No. 2005N-0373 and RIN number 0910-AF54
Greetings FDA et al, ONCE again I would kindly like to comment on the continuous failed attempts by the FDA to regulate the use of certain cattle material in, or in the manufacture including processing) of, drugs, biologics, and medical devices intended for use in humans and human cells, tissues, and cellular and tissue-based products (HCT/Ps) (collectively, medical products for humans), and in drugs intended for use in ruminant animals (drugs for ruminants) from the proven risk factors of Transmissible Spongiform Encephalopahy i.e. TSE's in all species. I have continued to warn the FDA et al about these risk factors via the surgical and medical arena (vaccines, nutritional supplements, bovine heart valves, and other animal donor tissue), and I have continued to point out the risk factor of the UKBSENVCJD only theory, and the ramifications there from, i.e. BASE (bovine amyloidotic spongiform encephalopathy), and my greatest fears, one I have warned you about time and time again, seems to be coming true ;
64. A member noted that at the recent Neuroprion meeting, a study was presented showing that in transgenic mice BSE passaged in sheep may be more virulent and infectious to a wider range of species than bovine derived BSE. Other work presented suggested that BSE and bovine amyloidotic spongiform encephalopathy (BASE) MAY BE RELATED. A mutation had been identified in the prion protein gene in an AMERICAN BASE CASE THAT WAS SIMILAR IN NATURE TO A MUTATION FOUND IN CASES OF SPORADIC CJD. A study also demonstrated that in a mouse model it was possible to alleviate the pathological changes of prion disease by suppressing expression of the prion protein gene after infection.

Interference at the EPA
Science and Politics at the U.S. Environmental Protection Agency
The U.S. Environmental Protection Agency (EPA) has the simple yet profound charge "to protect human health and the environment." EPA scientists apply their expertise to protect the public from air and water pollution, clean up hazardous waste, and study emerging threats such as global warming. Because each year brings new and potentially toxic chemicals into our homes and workplaces, because air pollution still threatens our public health, and because environmental challenges are becoming more complex and global, a strong and capable EPA is more important than ever.
Yet challenges from industry lobbyists and some political leaders to the agency's decisions have too often led to the suppression and distortion of the scientific findings underlying those decisions—to the detriment of both science and the health of our nation. While every regulatory agency must balance scientific findings with other considerations, policy makers need access to the highest-quality scientific information to make fully informed decisions.
Concern over this problem led the Union of Concerned Scientists (UCS) to investigate political interference in science at the EPA. The investigation combines dozens of interviews with current and former EPA staff, analysis of government documents, more than 1,600 responses to a survey sent to current EPA scientists, and written comments from EPA scientists.
The results of these investigations show an agency under siege from political pressures. On numerous issues—ranging from mercury pollution to groundwater contamination to climate change—political appointees have edited scientific documents, manipulated scientific assessments, and generally sought to undermine the science behind dozens of EPA regulations. ...

FDA scientists complain to Obama of 'corruption'

January 26, 2009
A kind greetings from Bacliff, Texas !
O.K., let us suppose the impossible, that indeed spontaneous Transmissible Spongiform Encephalopathy _does_ exists (to date, this has never been proven in the field, under natural conditions), at whatever rate they choose (i do not believe in the spontaneous TSE as the cause for 85%+ of all CJD i.e. the sporadic CJD's, i.e. that all these poor victims died from a 'happenstance of bad luck', or 'that a twisted funked out protein just chose this group on it's own, with no route and source of nothing involved'), BUT for now, lets say they exist.
PLEASE tell me then how a GM cow will be free from the spontaenous TSE ???
Spontaneous occurrence (14-16)
The evidence from the absence of BSE in many countries and the surveillance schemes abroad indicates that most BARBs cases cannot have arisen spontaneously, although the possibility cannot be excluded that a very few of them did so. The possibility of a very low frequency of spontaneous occurrence of BSE may be monitored from the output of surveillance in cattle populations elsewhere. R: A watching brief is kept on surveillance efforts world-wide.

Perspectives BIOMEDICINE: A Fresh Look at BSE Bruce Chesebro*
Mad cow disease, or bovine spongiform encephalopathy (BSE), is the cattle form of a family of progressive brain diseases. These diseases include scrapie in sheep, Creutzfeldt-Jakob disease (CJD) in humans, and chronic wasting disease (CWD) in deer and elk. They are also known as either "prion diseases" because of the association of a misfolded cellular prion protein in pathogenesis or "transmissible spongiform encephalopathies" (TSEs) because of the spongelike nature of the damaged brain tissue (1).
The recent discovery of two BSE-infected cows, one in Canada and one in the United States, has dramatically increased concern in North America among meat producers and consumers alike over the extent to which BSE poses a threat to humans as well as to domestic and wild animals. The European BSE epidemic of the late-1980s seems to have been initiated a decade earlier in the United Kingdom by changes in the production of meat and bone meal (MBM) from rendered livestock, which led to contamination of MBM with the BSE infectious agent. Furthermore, the fact that UK farmers fed this rendered MBM to younger animals and that this MBM was distributed to many countries may have contributed to the ensuing BSE epidemic in the United Kingdom and internationally (2).
Despite extensive knowledge about the spread of BSE through contaminated MBM, the source of BSE in Europe remains an unsolved mystery (2). It has been proposed that BSE could be derived from a cross-species infection, perhaps through contamination of MBM by scrapie-infected sheep tissues (see the figure). Alternatively, BSE may have been an endemic disease in cattle that went unnoticed because of its low level of horizontal transmission. Lastly, BSE might have originated by "spontaneous" misfolding of the normal cellular prion protein into the disease-associated abnormal isoform (3), which is postulated to be the infectious agent or "prion."
Five possible sources of BSE in North American cattle. Sheep, deer, and elk could spread prion diseases (TSEs) to cattle through direct animal contact or contamination of pastures. Endemic BSE has not been proven to exist anywhere in the world, but it is difficult to exclude this possibility because of the inefficient spread of BSE infectivity between individual animals (2). BSE caused by spontaneous misfolding of the prion protein has not been proven. CREDIT: KATHARINE SUTLIFF/SCIENCE
snip...
Nevertheless, the idea that BSE might originate due to the spontaneous misfolding of prion proteins has received renewed interest in the wake of reports suggesting the occurrence of atypical BSE (9-11). These results imply that new strains of cattle BSE might have originated separately from the main UK outbreak. Where and how might such strains have originated? Although such rare events cannot be studied directly, any number of sources of the original BSE strain could also explain the discovery of additional BSE strains in cattle (see the figure). However, it would be worrisome if spontaneous BSE were really a valid etiology because such a mechanism would be impossible to prevent--unlike other possible scenarios that could be controlled by large-scale eradication of TSE-positive animals.
Another way to look at this problem is to examine evidence for possible spontaneous TSE disease in other animals besides cattle. Spontaneous BSE would be extremely difficult to detect in cattle, where horizontal spread is minimal. However, in the case of the sheep TSE disease, scrapie, which spreads from ewes to lambs at birth as well as between adults, spontaneous disease should be detectable as new foci of clinical infection. In the early 1950s scrapie was eradicated in both Australia and New Zealand, and the mainland of both these countries has remained scrapie-free ever since. This scrapie-free status is not the result of selection of sheep resistant to scrapie because sheep from New Zealand are as susceptible as their UK counterparts to experimental scrapie infection (12). These experiments of man and nature appear to indicate that spontaneous clinical scrapie does not occur in sheep. Similarly, because CWD is known to spread horizontally, the lack of CWD in the deer or elk of eastern North America but its presence in western regions would also argue against a spontaneous disease mechanism. This is particularly noteworthy in New Zealand, where there are large numbers of deer and elk farms and yet no evidence of spontaneous CWD. If spontaneous scrapie does not occur in sheep or deer, this would suggest that spontaneous forms of BSE and sporadic Creutzfeldt-Jakob disease (sCJD) are unlikely to be found in cattle or humans. The main caveat to this notion is that spontaneous disease may arise in some animal species but not others. In humans, sCJD--which is considered by some researchers to begin by spontaneous misfolding of the prion protein--usually takes more than 50 years to appear. Thus, in animals with a shorter life-span, such as sheep, deer, and cattle, an analogous disease mechanism might not have time to develop.
What can we conclude so far about BSE in North America? Is the BSE detected in two North American cows sporadic or spontaneous or both? "Sporadic" pertains to the rarity of disease occurrence. "Spontaneous" pertains to a possible mechanism of origin of the disease. These are not equivalent terms. The rarity of BSE in North America qualifies it as a sporadic disease, but this low incidence does not provide information about cause. For the two reported North American BSE cases, exposure to contaminated MBM remains the most likely culprit. However, other mechanisms are still possible, including cross-infection by sheep with scrapie or cervids with CWD, horizontal transmission from cattle with endemic BSE, and spontaneous disease in individual cattle. Based on our understanding of other TSEs, the spontaneous mechanism is probably the least likely. Thus, "idiopathic" BSE--that is, BSE of unknown etiology--might be a better term to describe the origin of this malady. ...

Transcript of Remarks From Technical Briefing on BSE and Related Issues With Agriculture Secretary Ann M. Veneman and USDA Chief Veterinary Officer Dr. Ron DeHaven Washington D.C. - March 15, 2004
snip...
OPERATOR : “Yes. Our next one is coming from Elizabeth Weiss. Please state your company.”
ELIZABETH WEISS: “This is Elizabeth Weiss with USA Today.”
“I actually had two questions. First off, when you say you're looking for 1 in 10,000 cases, is USDA doing any work to find out the possibility of whether or not BSE exists in a spontaneous form in the way that it does in humans and elk populations?
“And secondly, how will any of this fit into some of the consternation that's been raised in California and with the Midwest packer that wanted to test all of its cattle?
“Thanks.”
DR. DEHAVEN: “All right. I think we've got three different questions in there, and I'll try to touch on each one of them.
“First of all, let me correct just a technical issue, and that is you mentioned 1 in 10,000. And actually our surveillance system currently is designed, the one that we have in place now is designed to detect 1 positive in 1 million cattle, and I gave some numbers between 200,000 and 268,000 that would allow us to detect 1 in 10 million as opposed to 1 in 10,000.
“So we would, if we were able to collect in the ballpark of those numbers of samples then we with increasing numbers of samples have an increasingly statistically valid sample from which to determine, one, whether or not the disease exists and, if so, at what prevalence level.
“So our real emphasis is to test as many of those animals as we can, ensure that we get an appropriate geographical distribution, but not setting a specific number as far as a target. Again, consistent with the recommendation from the International Review Team, their recommendation was to test all of them.
“So that's consistent with where we're going is to test as many as we possibly can.
“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.

UK TESTING FINISHED NEXT WEEK
Matthews confirmed that the brain tissue samples from the US animal had arrived at Weybridge. Test results were likely to be ready by the end of next week, he said.
The suspect animal has already undergone a series of tests. A rapid screening test on Nov. 15 returned inconclusive results. Sophisticated immunohistochemistry (IHC) tests cleared the animal of any infection, but a third round of testing using a Western blot procedure showed a "weak positive".
Weybridge will do an IHC test plus three kinds of Western Blot tests on the samples. They will use "methods of slightly different analytical sensitivity that give us the greatest number of opportunities to interpret what we see," he said.
US beef industry leaders say scientists should not speculate about the unusual case.
"There's no evidence that it's atypical ... and there's absolutely no evidence that it's spontaneous," said Gary Weber, head of regulatory affairs at the National Cattlemen's Beef Association.
Matthews noted scientists are still grappling with what is typical and atypical BSE.
"Far too few people have looked at BSE in depth using all of the tests to be able to define 'this is normal and that one isn't'," he said.
Weber noted Japan used the term to describe two very young infected cattle because BSE is usually found in older animals. Italy labeled a case "atypical" because the misshaped prions were found in unexpected parts of the animal's brain. ...snip...end

Atypical BSE strain -- In July 2007, the UK Spongiform Encephalopathy Advisory Committee (SEAC) suggested that atypical BSE may be a distinct strain of prion disease. Unlike typical BSE, cases of atypical BSE, according to SEAC, may have risen spontaneously (although transmission through feed or the environment cannot be ruled out). Recently reported French surveillance data support this theory that unlike typical BSE, atypical BSE appears to represent sporadic disease

http://www.defra.gov.uk/animalh/bse/pdf/hillreport.pdf
Spontaneous occurrence
14. Spontaneous cases of classical CJD in humans are found at a rate of about 1/million around the world (Will, 1993), without appreciable racial or geographical variation except in a few specific cases, notably Jews of Libyan origin that have a mutation in the open reading frame of the PRNP gene (Chapman and Korczyn, 1991). Thus it is theoretically possible that spontaneous cases of BSE could occur as a consequence of a germ line mutation, in which case relatives would also have a certain or increased incidence of the disease, or a somatic mutation, which would be unlikely to be detectable unless the appropriate tissue were identified, or after some transformation in the PrP protein in the animal concerned. BSE was unknown prior to its detection in Britain in the mid 1980s, and Index cases found around the world since then can all be explained in terms of export from the UK directly or indirectly of cattle or of feed components. No BSE affected animals have been reported in many developed countries with large cattle populations, including Australia, New Zealand, Norway and Sweden, which have mixed cattle populations; and the only infected animal detected in the US was of Canadian origin. The disease seems to have a highly homogeneous aetiology (e.g. Bruce, 2003).
15. Data from the USA, where the dairy population in particular is highly related to that in GB provide an upper limit to the spontaneous rate. A programme of testing is in place of a target population of adult cattle exhibiting some clinical sign that might be consistent with BSE (animals reported as having CNS or clinical signs of BSE or were non-ambulatory). In the intensive programme from June 2004 over 375000 animals were tested in the following 12 months. No positive results have yet been obtained in these or previous tests (USDA BSE Testing). This implies a putative upper limit of under 10 per million in this target group. Assuming, as analysis has shown, the relative risk in this group is about 30 times higher than in the population as a whole (European Commission, 2002c), then the incidence in the population as a whole is under 3 per 10 million. This figure could possibly be biased downwards if affected animals are diagnosed and disposed of without being tested. Taking account of testing done and the lack of clinical cases seen in many other countries also, it seems highly unlikely that the spontaneous rate can be as much as 3 per 10 million head. Nor can spontaneous occurrence explain incidences of ca. 30 cases of BARBs per year in 2002/4 in the UK adult cattle population of ca. 4 million. [NOTE ADDED 30 JUNE: The recent confirmation of a previously inconclusive case in the USA affects these calculations. If the animal did not have access to infected feed, the calculations have to be revised: they suggest a sporadic incidence in the population of 1/(375000 x 30) or almost 1 per 10 million, with the upper limit under 5 per 10 million.]
16. Calculation of a maximum rate of possible transformation from scrapie to BSE is less feasible. Nevertheless, BSE appears not to have arisen in the UK until around the early 1980s, despite the presence of scrapie in sheep here for at least 200 years. Although a change in the scrapie prion may have been the cause of the initial cases of BSE, the difference between their properties in mice and the uniformity of the BSE brain lesions suggest it is unlikely that more than one such mutation was the source of BSE. It is most unlikely that the same mutation could be occurring often enough to contribute significantly to BARBs cases. Furthermore BARBs cases do not match the geographical distribution of the sheep population. The evidence from the absence of BSE in many countries and the surveillance schemes abroad indicates that most BARBs cases cannot have arisen spontaneously, although the possibility cannot be excluded that a very ...

242 Atypical and classical BSE are different strains based upon Western blot profiles 243 (Hill, 2004; Normile, 2004; Baron et al., 2006), and this study indicates that disease Page 11 of 23 Journal of Animal Science Downloaded from jas.fass.org by on November 12, 2008. 12 progresses via different routes for these strains. The disparate 244 routes of pathogenesis in 245 atypical BSE can occur by 1 of 2 means. One possibility is that the source of infectivity 246 in atypical BSE is exposure to contaminated feedstuffs, as is the case for classical BSE, 247 but progression occurs in a disparate manner that bypasses the influence of the indel 248 polymorphisms. The other possibility is that atypical BSE is occurring spontaneously in 249 the host. Support for atypical BSE occurring spontaneously are the parallels to sporadic 250 TSE in humans, specifically, occurrence in older hosts and a comparable low incidence 251 rate (Baron and Biacabe, 2006). Furthermore, atypical BSE occurs as isolated, sporadic 252 cases in contrast to the clustering of cases observed for feed borne classical BSE 253 (Donnelly et al., 1997). Interestingly, the only native born cases of BSE in the United 254 States identified to date have been classified as atypical BSE.
255 No experiment can conclusively confirm a spontaneous nature for atypical BSE.

Emerging Concerns: De novo Formation of Prions
9:05 De novo Generation of Prion Infectivity in a Cell-Free System Joaquin Castilla, Ph.D., Assistant Professor, Department of Infectology, Scripps Research Institute-Florida Transmissible spongiform encephalopathies (TSEs) are a group of neurodegenerative disorders affecting both humans and animals. There is no available treatment or therapy for these fatal diseases. The infectious agent associated with TSEs (termed prion) appears to be composed uniquely of a protein, which is a conformationally-modified version (PrPSc) of the cellular prion protein (PrPC). The disease is propagated by the conversion of host PrPC into PrPSc induced by small quantities of PrPSc. Interestingly, prions occur in the form of different strains that show distinct biological and physicochemical properties. TSEs can have diverse origins, including genetic, sporadic (putatively spontaneous) and infectious. The occurrence of sporadic cases of prion diseases in humans and maybe in other species, i.e. atypical bovine spongiform encephalopathy (BSE) in European and USA cattle and atypical scrapie cases in sheep suggest that spontaneous prion diseases may happen infrequently but ubiquitously. However, there are no reported cases of spontaneously-occurring prion disease in experimental wild-type rodent models. We have used a novel technique, Protein Misfolding Cyclic Amplification (PMCA) to rapidly propagate prions in the test tube, using normal brain homogenate as substrate. Prions propagated in vitro are infectious in vivo and maintain their prion strain specificity. PMCA has been used to efficiently amplify a variety of prion strains from mouse, hamster, bank vole, deer, cattle, sheep and human. Therefore, to mimic spontaneous generation of infectivity in vitro becomes one of the most important challenges in the prion field. We show here, for the first time, the de novo generation of infectious prions from bank voles (Clethrionomys glareolus) starting with non-infectious brain homogenates. Several biochemically different prion strains were generated using two different wild-type vole genotypes. The de novo in vitro generated PrPSc was highly infectious after its inoculation in bank voles. We show an extensive characterization of this "spontaneous" phenomenon.

In a mouse model of disease we have shown high titres of TSE infectivity in brain tissue which contains little or no PrP-res. We also found no evidence of other abnormal PrP isofoms such as PK-sen PrPSc. These data question the true relationship between PrPSc and TSE infectivity, and the current reliance on PrPSc as the sole diagnostic marker for TSE disease.
12:00 Conversion of the BASE Prion into the BSE Prion: The Origin of BSE? Fabrizio Tagliavini, Ph.D., Director, Division of Neurology 5 & Neuropathology, Neurological Institute "Carlo Besta" Twenty years after the identification of bovine spongiform encephalopathy (BSE), the origin of the causal agent is still unknown. This issue is of fundamental importance, since knowledge of the origin of the BSE agent is essential for prevention of future outbreak of the disease or variants thereof in cattle and other mammals. We carried out transmission studies with transgenic mice expressing bovine PrP and four lines of non-transgenic mice and found that an atypical form of spongiform encephalopathy of cattle, termed BASE or BSE-L, is caused by a prion strain distinct from that of classical BSE. Noteworthy, this newly characterized prion strain has the ability to convert into the classical BSE strain upon serial transmission to inbred mouse lines. According to these results, BASE--which is regarded as a sporadic form of prion disease in cattle--may be the origin of BSE, following conversion of the causal agent in an intermediate host.

2:00 Sporadic CJD and Atypical BSE: Two Children of One Protein Maurizio Pocchiari, Ph.D., Director of Research, Virology, Istituto Superiore Di Sanita The identification of forms of TSE diseases in cattle caused by prion strains different from BSE has raised new concerns on the possibility that these novel agents might induce disease in humans with a phenotype resembling sporadic CJD. The analysis of the distribution of the different molecular subtypes of sporadic CJD might give some answers.

let's see, a few examples of our extensive BSE surveillance plan ;
On December 23, 2003, the U.S. Department of Agriculture (USDA) announced a presumptive diagnosis of the first known case of BSE in the United States. It was in an adult Holstein cow from Washington State. This diagnosis was confirmed by an international reference laboratory in Weybridge, England, on December 25. Trace-back based on an ear-tag identification number and subsequent genetic testing confirmed that the BSE-infected cow was imported into the United States from Canada in August 2001. Because the animal was non-ambulatory (a “downer cow”) at slaughter, brain tissue samples were taken by USDA’s Animal and Plant Health Inspection Service as part of its targeted surveillance for BSE. However the animal’s condition was attributed to complications from calving. After the animal was examined by a USDA Food Safety and Inspection Service (FSIS) veterinary medical officer both before and after slaughter, the carcass was released for use as food for human consumption. During slaughter, the tissues considered to be at high risk for the transmission of the BSE agent were removed. On December 24, 2003, FSIS recalled beef from cattle slaughtered in the same plant on the same day as the BSE positive cow. (see Bovine Spongiform Encephalopathy in a Dairy Cow - Washington State, 2003.)
On June 24, 2005, the USDA announced receipt of final results from The Veterinary Laboratories Agency in Weybridge, England, confirming BSE in a cow that had conflicting test results in 2004. This cow was from Texas, died at approximately 12 years of age, and represented the first endemic case of BSE in the United States. (see Texas BSE Investigation, Final Epidemiology Report, August 2005 (PDF – 83 KB))
On March 15, 2006, the USDA announced the confirmation of BSE in a cow in Alabama. The newly confirmed case was identified in a non-ambulatory (downer) cow on a farm in Alabama. The animal was euthanized by a local veterinarian and buried on the farm. The age of the cow was estimated by examination of the dentition as 10-years-old. It had no ear tags or distinctive marks; the herd of origin could not be identified despite an intense investigation (see second featured item above and Alabama BSE Investigation, Final Epidemiology Report, May 2006).

Strains of BSE There is increasing evidence that there are different strains of BSE: the typical BSE strain responsible for the outbreak in the United Kingdom and two atypical strains (H and L strains).
Typical BSE strain -- The BSE strain responsible for most of the BSE cases in Canada is the same classic or typical strain linked to the outbreak in the United Kingdom. It is known to be preventable through elimination of BSE contaminated feed and has been causally linked to vCJD in humans. This typical strain has not yet been identified in any U.S.-born cattle.
Atypical BSE strain -- In July 2007, the UK Spongiform Encephalopathy Advisory Committee (SEAC) suggested that atypical BSE may be a distinct strain of prion disease. Unlike typical BSE, cases of atypical BSE, according to SEAC, may have risen spontaneously (although transmission through feed or the environment cannot be ruled out). Recently reported French surveillance data support this theory that unlike typical BSE, atypical BSE appears to represent sporadic disease
Both of the U.S.-born BSE cases and two of the 15 Canadian-born BSE cases were 10 years of age or older and three of these older North American cases for whom the strain type is presently known were linked to an atypical BSE strain known as the H-strain. Publication of the strain testing results on the 13 year-old BSE-infected Canadian cow identified in December 2007 is pending.

Review on the epidemiology and dynamics of BSE epidemics

And last but not least, similarities of PrPres between Htype BSE and human prion diseases like CJD or GSS have been put forward [10], as well as between L-type BSE and CJD [17]. These findings raise questions about the origin and inter species transmission of these prion diseases that were discovered through the BSE active surveillance.
snip...
Cases of atypical BSE have only been found in countries having implemented large active surveillance programs. As of 1st September 2007, 36 cases (16 H, 20 L) have been described all over the world in cattle: Belgium (1 L) [23], Canada (1 H)15, Denmark (1 L)16, France (8 H, 6 L)17, Germany (1 H, 1 L) [13], Italy (3 L)18, Japan (1 L) [71], Netherlands (1 H, 2 L)19, Poland (1 H, 6 L)20, Sweden (1 H)21, United Kingdom (1 H)22, and USA (2 H)23. Another H-type case has been found in a 19 year old miniature zebu in a zoological park in Switzerland [56]. It is noteworthy that atypical cases have been found in countries that did not experience classical BSE so far, like Sweden, or in which only few cases of classical BSE have been found, like Canada or the USA.
And last but not least, similarities of PrPres between Htype BSE and human prion diseases like CJD or GSS have been put forward [10], as well as between L-type BSE and CJD [17].

In this context, a word is in order about the US testing program. After the discovery of the first (imported) cow in 2003, the magnitude of testing was much increased, reaching a level of >400,000 tests in 2005 (Figure 4). Neither of the 2 more recently indigenously infected older animals with nonspecific clinical features would have been detected without such testing, and neither would have been identified as atypical without confirmatory Western blots. Despite these facts, surveillance has now been decimated to 40,000 annual tests (USDA news release no. 0255.06, July 20, 2006) and invites the accusation that the United States will never know the true status of its involvement with BSE.
In short, a great deal of further work will need to be done before the phenotypic features and prevalence of atypical BSE are understood. More than a single strain may have been present from the beginning of the epidemic, but this possibility has been overlooked by virtue of the absence of widespread Western blot confirmatory testing of positive screening test results; or these new phenotypes may be found, at least in part, to result from infections at an older age by a typical BSE agent, rather than neonatal infections with new "strains" of BSE. Neither alternative has yet been investigated.

I lost my mother to hvCJD (Heidenhain Variant CJD). I would like to comment on the CDC's attempts to monitor the occurrence of emerging forms of CJD. Asante, Collinge et al [1] have reported that BSE transmission to the 129-methionine genotype can lead to an alternate phenotype that is indistinguishable from type 2 PrPSc, the commonest sporadic CJD. However, CJD and all human TSEs are not reportable nationally. CJD and all human TSEs must be made reportable in every state and internationally. I hope that the CDC does not continue to expect us to still believe that the 85%+ of all CJD cases which are sporadic are all spontaneous, without route/source. We have many TSEs in the USA in both animal and man. CWD in deer/elk is spreading rapidly and CWD does transmit to mink, ferret, cattle, and squirrel monkey by intracerebral inoculation. With the known incubation periods in other TSEs, oral transmission studies of CWD may take much longer. Every victim/family of CJD/TSEs should be asked about route and source of this agent. To prolong this will only spread the agent and needlessly expose others. In light of the findings of Asante and Collinge et al, there should be drastic measures to safeguard the medical and surgical arena from sporadic CJDs and all human TSEs. I only ponder how many sporadic CJDs in the USA are type 2 PrPSc?

Diagnosis and Reporting of Creutzfeldt-Jakob Disease
To the Editor: In their Research Letter, Dr Gibbons and colleagues1 reported that the annual US death rate due to Creutzfeldt-Jakob disease (CJD) has been stable since 1985. These estimates, however, are based only on reported cases, and do not include misdiagnosed or preclinical cases. It seems to me that misdiagnosis alone would drastically change these figures. An unknown number of persons with a diagnosis of Alzheimer disease in fact may have CJD, although only a small number of these patients receive the postmortem examination necessary to make this diagnosis. Furthermore, only a few states have made CJD reportable. Human and animal transmissible spongiform encephalopathies should be reportable nationwide and internationally.

FDA Scientists Complain About Corruption Inside The Agency
FDA scientists complain to Obama of 'corruption'
By RICARDO ALONSO-ZALDIVAR
updated 5:10 p.m. CT, Thurs., Jan. 8, 2009 WASHINGTON - In an unusually blunt letter, a group of federal scientists is complaining to the Obama transition team of widespread managerial misconduct in a division of the Food and Drug Administration.
"The purpose of this letter is to inform you that the scientific review process for medical devices at the FDA has been corrupted and distorted by current FDA managers, thereby placing the American people at risk," said the letter, dated Wednesday, on the letterhead of the agency's Center for Devices and Radiological Health.
The center is responsible for medical devices ranging from stents and breast implants to MRIs and other imaging machinery. The concerns of the nine scientists who wrote to the transition team echo some of the complaints from the FDA's drug review division a few years ago during the safety debacle involving the painkiller Vioxx.
The FDA declined to publicly respond to the letter, but said it is working to address the concerns.
In their letter, the FDA dissidents alleged that agency managers use intimidation to squelch scientific debate, leading to the approval of medical devices whose effectiveness is questionable and which may not be entirely safe.
A copy of the letter, with the names of the scientists redacted, was provided to The Associated Press by a congressional official.
FDA spokeswoman Judy Leon said in response: "We have been working very closely with members of the transition team and any concerns or questions they have on any issue, we will address directly with the team. Separately, the agency is actively engaged in a process to explore the staff members' concerns and take appropriate action."
Senior Democratic and Republican lawmakers are urging Obama to appoint a commissioner who will shake up the FDA and restore the confidence of its working-level scientists and medical experts. But industry officials fear that approval of new drugs and devices could be delayed by endless scientific disputes within the agency.

FDA Scientists Complain About Corruption Inside The Agency
By Anna Boyd 13:39, January 11th 2009
A group of nine scientists at the Food and Drug Administration sent a letter to President-elect Barack Obama and his transition team, asking for immediate intervention as the agency is “fundamentally broken” and fails to fulfill its mission.
“The purpose of this letter is to inform you that the scientific review process for medical devices at the FDA has been corrupted and distorted by current FDA managers, thereby placing the American people at risk,” read the six-page letter, written on the agency’s Center for Devices and radiological letterhead.
The scientists went even further and said there is an atmosphere at FDA in which the honest employee fears the dishonest one, when it should be the other way around. Moreover, the FDA has promoted and rewarded some of the managers involved with the inappropriate practices. They also complained about devices that have not been properly labeled, about managers without appropriate experience who have been given authority to make final decisions about device regulation and have done so while ignoring serious safety and effectiveness concerns, or of FDA experts who have been excluded from product meetings because manufacturers felt that they were "biased."
Responding to the accusations, agency spokeswoman Judy Leon said the FDA has been working “very closely” with Mr. Obama’s transition team and will address any issues or concerns the team presents. She added the agency is “actively engaged in a process to explore the staff members' concerns and take appropriate action.”
Members of the transition team weren't available to discuss over the issues in the letter or whether they intend to address it publicly.

FDA Scientists Ask For Obama’s Help To Fight Corruption Inside The Agency
By Irene Collins 18:43, January 10th 2009
It appears that some scientists at the FDA wrote to President-Elect Barack Obama’s transition team, basically begging for help and outlining a number of problems with an agency they describe as “fundamentally broken.” Nine scientists who claim the FDA is a “fundamentally broken” agency authored the letter, sent Wednesday and written on the agency’s Center for Devices and Radiological Health letterhead.
The letter, addressed to John Podesta, says the atmosphere at the agency is one where “the honest employee fears the dishonest employee.”
Podesta is head of the Obama transition team but others receiving copies include Tom Daschle, Obama’s pick to lead the Department of Health and Human Services; Joshua Sharfstein, the physician leading the transition team’s assessment of FDA activities; and Senator Edward Kennedy, chairman of the health committee.
The scientists wrote that they have raised their concerns with FDA Commissioner Andrew von Eschenbach and Bill McConagha, an attorney and the assistant commissioner for accountability and integrity at the agency, but added that the agency has taken no action to address the issues.
In addition, they wrote that FDA has promoted and rewarded some of the managers involved with the inappropriate practices. They also complained about devices that have not been properly labeled, about managers without appropriate experience who have been given authority to make final decisions about device regulation and have done so while ignoring serious safety and effectiveness concerns, or of FDA experts who have been excluded from product meetings because manufacturers felt that they were "biased."
The Obama transition team has not issued a statement about the scientists’ complaint of corruption among FDA managers.

Interference at the EPA
Science and Politics at the U.S. Environmental Protection Agency
The U.S. Environmental Protection Agency (EPA) has the simple yet profound charge "to protect human health and the environment." EPA scientists apply their expertise to protect the public from air and water pollution, clean up hazardous waste, and study emerging threats such as global warming. Because each year brings new and potentially toxic chemicals into our homes and workplaces, because air pollution still threatens our public health, and because environmental challenges are becoming more complex and global, a strong and capable EPA is more important than ever.
Yet challenges from industry lobbyists and some political leaders to the agency's decisions have too often led to the suppression and distortion of the scientific findings underlying those decisions—to the detriment of both science and the health of our nation. While every regulatory agency must balance scientific findings with other considerations, policy makers need access to the highest-quality scientific information to make fully informed decisions.
Concern over this problem led the Union of Concerned Scientists (UCS) to investigate political interference in science at the EPA. The investigation combines dozens of interviews with current and former EPA staff, analysis of government documents, more than 1,600 responses to a survey sent to current EPA scientists, and written comments from EPA scientists.
The results of these investigations show an agency under siege from political pressures. On numerous issues—ranging from mercury pollution to groundwater contamination to climate change—political appointees have edited scientific documents, manipulated scientific assessments, and generally sought to undermine the science behind dozens of EPA regulations. ...

MAD COW DISEASE USA DECEMBER 28, 2008 an 8 year review of a failed and flawed policy
Greetings,
I thought a quick review of the Bush's terribly flawed and failed mad cow disease policy, from the illegal feeding of literally millions and millions of pounds of highly suspect, and banned mad feed, to the failed BSE surveillance program, all of which exposed, needlessly, millions of people to the mad cow agent i.e. Transmissible Spongiform Encephalopathy. ...

USDA CERTIFIED DEADSTOCK DOWNER COW SCHOOL LUNCH PROGRAM

Terry S. Singeltary Sr. P.O. Box 42 Bacliff, Texas USA 77518
By RICARDO ALONSO-ZALDIVAR
updated 5:10 p.m. CT, Thurs., Jan. 8, 2009 WASHINGTON - In an unusually blunt letter, a group of federal scientists is complaining to the Obama transition team of widespread managerial misconduct in a division of the Food and Drug Administration.
"The purpose of this letter is to inform you that the scientific review process for medical devices at the FDA has been corrupted and distorted by current FDA managers, thereby placing the American people at risk," said the letter, dated Wednesday, on the letterhead of the agency's Center for Devices and Radiological Health.
The center is responsible for medical devices ranging from stents and breast implants to MRIs and other imaging machinery. The concerns of the nine scientists who wrote to the transition team echo some of the complaints from the FDA's drug review division a few years ago during the safety debacle involving the painkiller Vioxx.
The FDA declined to publicly respond to the letter, but said it is working to address the concerns.
In their letter, the FDA dissidents alleged that agency managers use intimidation to squelch scientific debate, leading to the approval of medical devices whose effectiveness is questionable and which may not be entirely safe.
A copy of the letter, with the names of the scientists redacted, was provided to The Associated Press by a congressional official.
FDA spokeswoman Judy Leon said in response: "We have been working very closely with members of the transition team and any concerns or questions they have on any issue, we will address directly with the team. Separately, the agency is actively engaged in a process to explore the staff members' concerns and take appropriate action."
Senior Democratic and Republican lawmakers are urging Obama to appoint a commissioner who will shake up the FDA and restore the confidence of its working-level scientists and medical experts. But industry officials fear that approval of new drugs and devices could be delayed by endless scientific disputes within the agency.

FDA Scientists Complain About Corruption Inside The Agency
By Anna Boyd 13:39, January 11th 2009
A group of nine scientists at the Food and Drug Administration sent a letter to President-elect Barack Obama and his transition team, asking for immediate intervention as the agency is “fundamentally broken” and fails to fulfill its mission.
“The purpose of this letter is to inform you that the scientific review process for medical devices at the FDA has been corrupted and distorted by current FDA managers, thereby placing the American people at risk,” read the six-page letter, written on the agency’s Center for Devices and radiological letterhead.
The scientists went even further and said there is an atmosphere at FDA in which the honest employee fears the dishonest one, when it should be the other way around. Moreover, the FDA has promoted and rewarded some of the managers involved with the inappropriate practices. They also complained about devices that have not been properly labeled, about managers without appropriate experience who have been given authority to make final decisions about device regulation and have done so while ignoring serious safety and effectiveness concerns, or of FDA experts who have been excluded from product meetings because manufacturers felt that they were "biased."
Responding to the accusations, agency spokeswoman Judy Leon said the FDA has been working “very closely” with Mr. Obama’s transition team and will address any issues or concerns the team presents. She added the agency is “actively engaged in a process to explore the staff members' concerns and take appropriate action.”
Members of the transition team weren't available to discuss over the issues in the letter or whether they intend to address it publicly.

FDA Scientists Ask For Obama’s Help To Fight Corruption Inside The Agency
By Irene Collins 18:43, January 10th 2009
It appears that some scientists at the FDA wrote to President-Elect Barack Obama’s transition team, basically begging for help and outlining a number of problems with an agency they describe as “fundamentally broken.” Nine scientists who claim the FDA is a “fundamentally broken” agency authored the letter, sent Wednesday and written on the agency’s Center for Devices and Radiological Health letterhead.
The letter, addressed to John Podesta, says the atmosphere at the agency is one where “the honest employee fears the dishonest employee.”
Podesta is head of the Obama transition team but others receiving copies include Tom Daschle, Obama’s pick to lead the Department of Health and Human Services; Joshua Sharfstein, the physician leading the transition team’s assessment of FDA activities; and Senator Edward Kennedy, chairman of the health committee.
The scientists wrote that they have raised their concerns with FDA Commissioner Andrew von Eschenbach and Bill McConagha, an attorney and the assistant commissioner for accountability and integrity at the agency, but added that the agency has taken no action to address the issues.
In addition, they wrote that FDA has promoted and rewarded some of the managers involved with the inappropriate practices. They also complained about devices that have not been properly labeled, about managers without appropriate experience who have been given authority to make final decisions about device regulation and have done so while ignoring serious safety and effectiveness concerns, or of FDA experts who have been excluded from product meetings because manufacturers felt that they were "biased."
The Obama transition team has not issued a statement about the scientists’ complaint of corruption among FDA managers.

For whatever it's worth, myself and others have been asking for an investigation into the FDA and the USDA et al for a decade or more. ...TSS
