The pathogenesis of bovine spongiform encephalopathy (BSE) infections in cattle has been studied in recent years by using highly sensitive transgenic mouse bioassays. It has been shown that in this species, the BSE agent amplifies almost exclusively in the central and peripheral nervous system. Even in animals that were killed in the clinical end stage of the disease, the lymphoreticular system was shown to be free of the infectious agent. No other animal species investigated to date exhibit such a restricted BSE infectivity distribution pattern. However, there is growing evidence for a centrifugal spread from the central nervous system (CNS) into the periphery at the late stages of the disease. In this study, we challenged transgenic mice overexpressing the bovine prion protein with homogenates prepared from a wide variety of tissue samples collected from BSE infected cattle. As prion infections involve the conversion of the cellular prion protein into its abnormally folded isoform (PrPSc), we applied various detection methods, such as the purification of scrapie-associated fibrils (SAF), immunohistochemistry (IHC), and the protein misfolding cyclic amplification (PMCA) technique. Despite negative results using these highly sensitive biochemical methods, we were for the first time able to detect BSE infectivity in the tongue and in the nasal mucosa of terminally diseased BSE field cases as well as experimentally challenged cattle by transgenic mouse bioassay. This shows that BSE infectivity can be present in peripheral tissues of terminally diseased cattle, including tissues used for human consumption.

North Dakota Firm Recalls Whole Beef Head Products That Contain Prohibited Materials

Recall Release CLASS II RECALL FSIS-RC-023-2010 HEALTH RISK: LOW

Congressional and Public Affairs (202) 720-9113 Catherine Cochran

WASHINGTON, April 5, 2010 - North American Bison Co-Op, a New Rockford, N.D., establishment is recalling approximately 25,000 pounds of whole beef heads containing tongues that may not have had the tonsils completely removed, which is not compliant with regulations that require the removal of tonsils from cattle of all ages, the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) announced today.

Tonsils are considered a specified risk material (SRM) and must be removed from cattle of all ages in accordance with FSIS regulations. SRMs are tissues that are known to contain the infective agent in cattle infected with Bovine Spongiform Encephalopathy (BSE), as well as materials that are closely associated with these potentially infective tissues. Therefore, FSIS prohibits SRMs from use as human food to minimize potential human exposure to the BSE agent.

The product subject to recall includes: Various weight cases of "Beef Heads KEEP FROZEN." Each case bears the establishment number "EST. 18859" inside the USDA mark of inspection and a case code number "16999." "North Dakota Natural Beef" is printed in the bottom left-hand corner of each label.

The recalled products were produced between June 25, 2009, and February 19, 2010. These products were shipped to distribution centers in Md., Mich., and Minn. for further sale.

The problem was discovered during FSIS inspection activities at the establishment. FSIS routinely conducts recall effectiveness checks to verify recalling firms notify their customers of the recall and that steps are taken to make certain that the product is no longer available to consumers.

Media with questions about the recall should contact Philip Wicke, Vice President of Operations, at (701) 356-7723. Consumers with questions about the recall should contact Jeremy Anderson, Director of Customer Service, at (952) 545-2495.

Consumers with food safety questions can "Ask Karen," the FSIS virtual representative available 24 hours a day at AskKaren.gov. The toll-free USDA Meat and Poultry Hotline 1-888-MPHotline (1-888-674-6854) is available in English and Spanish and can be reached from l0 a.m. to 4 p.m. (Eastern Time) Monday through Friday. Recorded food safety messages are available 24 hours a day. #

THIS is just ONE month report, of TWO recalls of prohibited banned MBM, which is illegal, mixed with 85% blood meal, which is still legal, but yet we know the TSE/BSE agent will transmit blood. we have this l-BSE in North America that is much more virulent and there is much concern with blood issue and l-BSE as there is with nvCJD in humans. some are even starting to be concerned with sporadic CJD and blood, and there are studies showing transmission there as well. ... this is one month recall page, where 10 MILLION POUNDS OF BANNED MAD COW FEED WENT OUT INTO COMMERCE, TO BE FED OUT. very little of the product that reaches commerce is ever returned via recall, very, very little. this was 2007, TEN YEARS AFTER THE AUGUST 4, 1997, PARTIAL AND VOLUNTARY MAD COW FEED BAN IN THE USA, that was nothing but ink on paper. i have listed the tonnage of mad cow feed that was in ALABAMA in one of the links too, this is where the infamous g-h-BSEalabama case was, a genetic relation matching the new sporadic CJD in the USA. seems this saga just keeps getting better and better.......$$$

Owner and Corporation Plead Guilty to Defrauding Bovine Spongiform Encephalopathy (BSE) Surveillance Program

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.

Finding 2 Inherent Challenges in Identifying and Testing High-Risk Cattle Still Remain

http://www.usda.gov/oig/webdocs/50601-10-KC.pdf


"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.

Discussion:

The C, L and H type BSE cases in Canada exhibit molecular characteristics similar to those described for classical and atypical BSE cases from Europe and Japan. This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada. It also suggests a similar cause or source for atypical BSE in these countries.

Transmission of BSE to Cynomolgus Macaque, a Non-human Primate; Development of Clinical Symptoms and Tissue Distribution of PrPSC

Two of three cynomolgus monkeys developed abnormal neuronal behavioral signs at 30-(#7) and 28-(#10) months after intracerebral inoculation of 200ul of 10% brain homogenates of BSE affected cattle (BSE/JP6). Around 30 months post inoculation (mpi), they developed sporadic anorexia and hyperekplexia with squeal against environmental stimulations such as light and sound. Tremor, myoclonic jerk and paralysis became conspicuous during 32 to 33-mpi, and symptoms become worsened according to the disease progression. Finally, one monkey (#7) fell into total paralysis at 36-mpi. This monkey was sacrificed at 10 days after intensive veterinary care including infusion and per oral supply of liquid food. The other monkey (#10) had to grasp the cage bars to keep an upright posture caused by the sever ataxia. This monkey was sacrificed at 35-mpi. EEG of both monkeys showed diffuse slowing. PSD characteristic for sporadic CJD was not observed in both monkeys. The result of forearm movement test showed the hypofunction that was observed at onset of clinical symptoms. Their cognitive function determined by finger maze test was maintained at the early stage of sideration. However, it was rapidly impaired followed by the disease progression. Their autopsied tissues were immunochemically investigated for the tissue distribution of PrPSc. Severe spongiform change in the brain together with heavy accumulation of PrPSc having the type 2B/4 glycoform profile confirmed successful transmission of BSE to Cynomolgus macaques. Granular and linear deposition of PrPSC was detected by IHC in the CNS of both monkeys. At cerebral cortex, PrPSC was prominently accumulated in the large plaques. Sparse accumulation of PrPSc was detected in several peripheral nerves of #7 but not in #10 monkey, upon the WB analysis. Neither #7 nor #10 monkey accumulated detectable amounts of PrPSc in their lymphatic organs such as tonsil, spleen, adrenal grands and thymus although PrPSc was barely detected in the submandibular lymph node of #7 monkey. Such confined tissue distribution of PrPSc after intracerebral infection with BSE agent is not compatible to that reported on the Cynomolgus macaques infected with BSE by oral or intra-venous (intra-peritoneal) routs, in which PrPSc was accumulated at not only CNS but also widely distributed lymphatic tissues.

Clustering of PrPres in Central Brain Regions of BSE-infected Macaques (M. Fascicularis)

Motzkus, D1; Montag, J1; Hunsmann, G1; Schulz-Schaeffer, W2 1German Primate Center, Dept. Virology and Immunology, Germany; 2University of Göttingen, Dept. Neuropathology, Germany

According to biochemical and epidemiological findings bovine spongiform encephalopathy (BSE) was transmitted to humans causing variant Creutzfeldt Jakob disease (vCJD). Previous studies have shown intracerebral (i.c.) transmission of BSE affected brain from cattle can cause TSEs in cynomolgus macaques (M. fascicularis). The lesion profile resembles that of vCJD. Recently, oral infection of M. fascicularis with macaque-adapted BSE material was reported. In cooperation with five European partners a quantitative study for the transmission of the BSE agent to M. fascicularis was initiated to assess the risk of vCJD infection in humans through contaminated food products (EU study QLK1-CT-2002-01096). Titration was performed orally and intracerebrally to determine the minimal infectious dose for cynomolgus monkeys. Here we report the outcome of the intracerebral infection with 50 mg BSE brain homogenate in six non-human primates. All animals showed clinical symptoms of TSE after an average of 1100 days. Using immunohistological and biochemical methods prion protein (PrP) deposits were confirmed in the brains of all animals. Using Western blot analysis the glycosylation pattern was compared to the inoculum and to the pattern of different CJD subtypes. Simian PrPres was detected with the monoclonal anti prion antibody 11C6, which revealed a higher sensitivity in comparison to 12F10 and 3F4. We found that the PrP glycopattern in BSE-infected cynomolgus macaques resembles human CJD type 2. We further analysed the distribution of PrPres by microdissection of seven different brain regions of all infected macaques. High concentrations of PrPres were detected in central brain regions, as gyrus cinguli, nucleus caudatus, vermis cerebelli and basis pontis. In contrast, in the peripheral regions gyrus frontalis, gyrus parietalis and gyrus occipitalis PrPres was hardly detectable.

Thus, the incubation period related to the life expectancy, the PrPres glycosylation pattern as well as the distribution in certain brain regions resemble those in vCJD patients. The relative abundance of PrPres in macaques will be compared to that of orally infected animals.

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 vCJD as fast as intracerebrally inoculated animals.

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

Spread of BSE prions in cynomolgus monkeys (Macaca fascicularis) after oral transmission

Edgar Holznagel1, Walter Schulz-Schaeffer2, Barbara Yutzy1, Gerhard Hunsmann3, Johannes Loewer1 1Paul-Ehrlich-Institut, Federal Institute for Sera and Vaccines, Germany; 2Department of Neuropathology, Georg-August University, Göttingen, Germany, 3Department of Virology and Immunology, German Primate Centre, Göttingen, Germany

Background: BSE-infected cynomolgus monkeys represent a relevant animal model to study the pathogenesis of variant Creutzfeldt-Jacob disease (vCJD).

Objectives: To study the spread of BSE prions during the asymptomatic phase of infection in a simian animal model.

Methods: Orally BSE-dosed macaques (n=10) were sacrificed at defined time points during the incubation period and 7 orally BSE-dosed macaques were sacrificed after the onset of clinical signs. Neuronal and non-neuronal tissues were tested for the presence of proteinase-K-resistant prion protein (PrPres) by western immunoblot and by paraffin-embedded tissue (PET) blot technique.

Results: In clinically diseased macaques (5 years p.i. + 6 mo.), PrPres deposits were widely spread in neuronal tissues (including the peripheral sympathetic and parasympathetic nervous system) and in lymphoid tissues including tonsils. In asymptomatic disease carriers, PrPres deposits could be detected in intestinal lymph nodes as early as 1 year p.i., but CNS tissues were negative until 3 – 4 years p.i. Lumbal/sacral segments of the spinal cord and medulla oblongata were PrPres positive as early as 4.1 years p.i., whereas sympathetic trunk and all thoracic/cervical segments of the spinal cord were still negative for PrPres. However, tonsil samples were negative in all asymptomatic cases.

Discussion: There is evidence for an early spread of BSE to the CNS via autonomic fibres of the splanchnic and vagus nerves indicating that trans-synaptical spread may be a time-limiting factor for neuroinvasion. Tonsils were predominantly negative during the main part of the incubation period indicating that epidemiological vCJD screening results based on the detection of PrPres in tonsil biopsies may mostly tend to underestimate the prevalence of vCJD among humans.

O.4.4

PrPSc distribution pattern in cattle experimentally challenged with H-type and L-type atypical BSE

Anne Buschmann1, Ute Ziegler1, Leila McIntyre2, Markus Keller1, Ron Rogers3, Bob Hills3, Martin H. Groschup1 1Friedrich-Loeffler-Institut, INEID, Germany; 2Faculty of Veterinary Medicine, University of Calgary, Canada; 3Health Canada, Ottawa, Canada

Background: After the detection of two novel BSE forms designated H-type and L-type BSE, the question of the pathogenesis and the agent distribution in cattle affected with these forms was fully open. From initial studies, it was already known that the PrPSc distribution in L-type BSE affected cattle differed from that known for classical BSE (C-type) where the obex region always displays the highest PrPSc concentrations. In contrast in L-type BSE cases, the thalamus and frontal cortex regions showed the highest levels of the pathological prion protein, while the obex region was only weakly involved. No information was available on the distribution pattern in H-type BSE.

Objectives: To analyse the PrPSc and infectivity distribution in cattle experimentally challenged with H-type and L-type BSE.

Methods: We analysed CNS and peripheral tissue samples collected from cattle that were intracranially challenged with Htype (five animals) and L-type (six animals) using a commercial BSE rapid test (IDEXX HerdChek), immunohistochemistry (IHC) and a highly sensitive Western blot protocol including a phosphotungstic acid precipitation of PrPSc (PTA-WB). Samples collected during the preclinical and the clinical stages of the disease were examined. For the detection of BSE infectivity, selected samples were also inoculated into highly sensitive Tgbov XV mice overexpressing bovine prion protein (PrPC).

Results: Analysis of a collection of fifty samples from the peripheral nervous, lymphoreticular, digestive, reproductive, respiratory and musculo-skeletal systems by PTA-WB, IDEXXHerdChek BSE EIA and IHC revealed a general restriction of the PrPSc accumulation to the central nervous system.

Discussion: Our results on the PrPSc distribution in peripheral tissues of cattle affected with H-type and L-type BSE are generally in accordance with what has been known for C-type BSE. Bioassays are ongoing in highly sensitive transgenic mice in order to reveal infectivity.

O.11.3

Infectivity in skeletal muscle of BASE-infected cattle

Groschup3, Anne Buschmann3, Cristina Casalone4, Maria Caramelli4, Salvatore Monaco5, Gianluigi Zanusso5, Fabrizio Tagliavini1 1Carlo Besta” Neurological Institute,Italy; 2IZS Brescia, Italy; 33FLI Insel Riems, D, Germany; 4CEA-IZS Torino, Italy; 5University of Verona, Italy

Background: BASE is an atypical form of bovine spongiform encephalopathy caused by a prion strain distinct from that of BSE. Upon experimental transmission to cattle, BASE induces a previously unrecognized disease phenotype marked by mental dullness and progressive atrophy of hind limb musculature. Whether affected muscles contain infectivity is unknown. This is a critical issue since the BASE strain is readily transmissible to a variety of hosts including primates, suggesting that humans may be susceptible.

Objectives: To investigate the distribution of infectivity in peripheral tissues of cattle experimentally infected with BASE. Methods: Groups of Tg mice expressing bovine PrP (Tgbov XV, n= 7-15/group) were inoculated both i.c. and i.p. with 10% homogenates of a variety of tissues including brain, spleen, cervical lymph node, kidney and skeletal muscle (m. longissimus dorsi) from cattle intracerebrally infected with BASE. No PrPres was detectable in the peripheral tissues used for inoculation either by immunohistochemistry or Western blot.

Results: Mice inoculated with BASE-brain homogenates showed clinical signs of disease with incubation and survival times of 175±15 and 207±12 days. Five out of seven mice challenged with skeletal muscle developed a similar neurological disorder, with incubation and survival times of 380±11 and 410±12 days. At present (700 days after inoculation) mice challenged with the other peripheral tissues are still healthy. The neuropathological phenotype and PrPres type of the affected mice inoculated either with brain or muscle were indistinguishable and matched those of Tgbov XV mice infected with natural BASE.

Discussion: Our data indicate that the skeletal muscle of cattle experimentally infected with BASE contains significant amount of infectivity, at variance with BSE-affected cattle, raising the issue of intraspecies transmission and the potential risk for humans. Experiments are in progress to assess the presence of infectivity in skeletal muscles of natural BASE.

P.5.3

Differences in the expression levels of selected genes in the brain tissue of cattle naturally infected with classical and atypical BSE.

Magdalena Larska1, Miroslaw P. Polak1, Jan F. Zmudzinski1, Juan M. Torres2 1National Veterinary Institute, Poland; 2CISA/INIA

Background: Recently cases of BSE in older cattle named BSE type L and type H were distinguished on the basis of atypical glycoprofiles of PrPres. The nature of those strains is still not fully understood but it is suspected that the atypical BSE cases are sporadic. Hitherto most BSE cases were studied in respect to the features of PrPSc. Here we propose gene expression profiling as a method to characterize and distinguish BSE strains.

Objectives: The aim of the study was to compare the activities of some factors which are known to play a role in TSE’s pathogenesis in order to distinguish the differences/similarities between all BSE types.

Methods: 10 % homogenate of brain stem tissue collected from obex region of medulla oblongata from 20 naturally infected BSE cows (8 assigned as classical BSE, other 8 and 4 infected with atypical BSE L type and H type respectively) was used in the study. As negative control animals we’ve used 8 animals in the age between 2.5 and 13 years. The genes were relatively quantified using SYBR Green real time RT-PCR. Raw data of Ct values was transformed into normalized relative quantities using Qbase Plus®. Results and

Discussion: In most of the tested genes significant differences in the expression levels between the brain stem of healthy cattle and animals infected with different BSE types were observed. In c-type BSE in comparison to healthy and atypical BSE the overexpression of the gene of bcl-2, caspase 3, 14-3-3 and tylosine kinase Fyn was significant.

Simultaneously in atypical BSEs type-L and type-H the levels of prion protein, Bax and LPR gene was elevated in comparison to c-BSE. Additionally L-BSE was characterized by the overexpression of STI1 and SOD genes compared to the other of BSE types. The downregulation of the gene encoding NCAM1 was observed in all BSE types in comparison to healthy cows. Different gene expression profiles of bovine brains infected with classical and atypical BSE indicates possible different pathogenesis or source of the disease.

Transmission of uncommon forms of bovine prions to transgenic mice expressing human PrP: questions and progress

Vincent Béringue, Hubert Laude INRA, UR 892, Virologie Immunologie Moléculaires, France

The active, large-scale testing of livestock nervous tissues for the presence of protease-resistant prion protein (PrPres) has led to the recognition of 2 uncommon PrPres molecular signatures, termed H-type and L-type BSE. Their experimental transmission to various transgenic and inbred mouse lines unambiguously demonstrated the infectious nature of such cases and the existence of distinct prion strains in cattle. Like the classical BSE agent, H- and L-type (or BASE) prions can propagate in heterologous species. In addition L-type prions acquire molecular and neuropathologic phenotypic traits undistinguishable from BSE or BSE-related agents upon transmission to transgenic mice expressing ovine PrP (VRQ allele) or wild-type mice. An understanding of the transmission properties of these newly recognized prions when confronted with human PrP sequence was therefore needed. Toward this end, we inoculated mice expressing human PrP Met129 with several field isolates. Unlike classical BSE agent, L-type prions appeared to propagate in these mice with no obvious transmission barrier. In contrast, we repeatedly failed to infect them with Htype prions. Ongoing investigations aim to extend the knowledge on these uncommon strains: are these agents able to colonize lymphoid tissue, a potential key factor for successful transmission by peripheral route; is there any relationship between these assumedly sporadic forms of TSE in cattle and some sporadic forms of human CJD are among the issues that need to be addressed for a careful assessment of the risk for cattle-to-human transmission of H- and L-type prions.


P.4.23

Transmission of atypical BSE in humanized mouse models

Liuting Qing1, Wenquan Zou1, Cristina Casalone2, Martin Groschup3, Miroslaw Polak4, Maria Caramelli2, Pierluigi Gambetti1, Juergen Richt5, Qingzhong Kong1 1Case Western Reserve University, USA; 2Instituto Zooprofilattico Sperimentale, Italy; 3Friedrich-Loeffler-Institut, Germany; 4National Veterinary Research Institute, Poland; 5Kansas State University (Previously at USDA National Animal Disease Center), USA

Background: Classical BSE is a world-wide prion disease in cattle, and the classical BSE strain (BSE-C) has led to over 200 cases of clinical human infection (variant CJD). Atypical BSE cases have been discovered in three continents since 2004; they include the L-type (also named BASE), the H-type, and the first reported case of naturally occurring BSE with mutated bovine PRNP (termed BSE-M). The public health risks posed by atypical BSE were largely undefined.

Objectives: To investigate these atypical BSE types in terms of their transmissibility and phenotypes in humanized mice. Methods: Transgenic mice expressing human PrP were inoculated with several classical (C-type) and atypical (L-, H-, or Mtype) BSE isolates, and the transmission rate, incubation time, characteristics and distribution of PrPSc, symptoms, and histopathology were or will be examined and compared.

Results: Sixty percent of BASE-inoculated humanized mice became infected with minimal spongiosis and an average incubation time of 20-22 months, whereas only one of the C-type BSE-inoculated mice developed prion disease after more than 2 years. Protease-resistant PrPSc in BASE-infected humanized Tg mouse brains was biochemically different from bovine BASE or sCJD. PrPSc was also detected in the spleen of 22% of BASE-infected humanized mice, but not in those infected with sCJD. Secondary transmission of BASE in the humanized mice led to a small reduction in incubation time. The atypical BSE-H strain is also transmissible with distinct phenotypes in the humanized mice, but no BSE-M transmission has been observed so far.

Discussion: Our results demonstrate that BASE is more virulent than classical BSE, has a lymphotropic phenotype, and displays a modest transmission barrier in our humanized mice.

BSE-H is also transmissible in our humanized Tg mice.

The possibility of more than two atypical BSE strains will be discussed.

Simian vCJD can be easily triggered in cynomolgus monkeys on the oral route using less than 5 g BSE brain homogenate.

http://www.prion2007.com/pdf/Prion%20Book%20of%20Abstracts.pdf



WE know now, and we knew decades ago, that 5.5 grams of suspect feed in TEXAS was enough to kill 100 cows.

look at the table and you'll see that as little as 1 mg (or 0.001 gm) caused 7% (1 of 14) of the cows to come down with BSE;

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.

LET'S take a closer look at this new prionpathy or prionopathy, and then let's look at the g-h-BSEalabama mad cow.

This new prionopathy in humans? the genetic makeup is IDENTICAL to the g-h-BSEalabama mad cow, the only _documented_ mad cow in the world to date like this, ......wait, it get's better. this new prionpathy is killing young and old humans, with LONG DURATION from onset of symptoms to death, and the symptoms are very similar to nvCJD victims, OH, and the plaques are very similar in some cases too, bbbut, it's not related to the g-h-BSEalabama cow, WAIT NOW, it gets even better, the new human prionpathy that they claim is a genetic TSE, has no relation to any gene mutation in that family. daaa, ya think it could be related to that mad cow with the same genetic make-up ??? there were literally tons and tons of banned mad cow protein in Alabama in commerce, and none of it transmitted to cows, and the cows to humans there from ??? r i g h t $$$

ALABAMA MAD COW g-h-BSEalabama

In this study, we identified a novel mutation in the bovine prion protein gene (Prnp), called E211K, of a confirmed BSE positive cow from Alabama, United States of America. This mutation is identical to the E200K pathogenic mutation found in humans with a genetic form of CJD. This finding represents the first report of a confirmed case of BSE with a potential pathogenic mutation within the bovine Prnp gene. We hypothesize that the bovine Prnp E211K mutation most likely has caused BSE in "the approximately 10-year-old cow" carrying the E221K mutation.

re-Freedom of Information Act Project Number 3625-32000-086-05, Study of Atypical BSE UPDATE July 28, 2010

http://bse-atypical.blogspot.com/2010/07/re-freedom-of-information-act-project.html


Discussion:

The C, L and H type BSE cases in Canada exhibit molecular characteristics similar to those described for classical and atypical BSE cases from Europe and Japan. This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada. It also suggests a similar cause or source for atypical BSE in these countries.

REPORT OF THE WORKING PARTY ON BOVINE SPONGIFORM ENCEPHALOPATHY 1989

snip...

4.2.9 ...Also, if it resulted from a localised chance transmission of the scrapie strain from sheep to cattle giving rise to a mutant, a different pattern of disease would have been expected: its range would have increased with time. Thus the evidence from Britain is against the disease being due to a new strain of the agent, but we note that in the United States from 1984 to 1988 outbreaks of scrapie in sheep flocks are reported to have Increased markedly, now being nearly 3 times as high as during any previous period (18).

Linda was a Hispanic female with no past medical history presents with 14 months of incresing/progressive altered mental status, generalized weakness, inability to walk, loss of appetite, inability to speak, tremor and bowel/blader incontinence. She was, in her usual state of health up until February, 2009, when her husbans notes that she began forgetting things like names and short term memories. He also noticed mild/vague personality changes such as increased aggression. In March, she was involved in a hit and run MVA,although she was not injured. The police tracked her down and ticketed her. At that time, her son deployed to Iraq with the Army and her husband assumed her mentation changes were due to stress over these two events. Also in March, she began to have weakness in her legs, making it difficult to walk. Over the next few months, her mentation and personality changes worsened, getting to a point where she could no longer recognized her children. She was eating less and less. She was losing more weight. In the last 2-3 months, she reached the point where she could not walk without an assist, then 1 month ago, she stopped talking, only making grunting/aggressive sounds when anyone came near her. She also became both bowel and bladder incontinent, having to wear diapers. Her '"tremor'" and body jerks worsened and her hands assumed a sort of permanent grip position, leading her family to put tennis balls in her hands to protect her fingers. The husband says that they have lived in Nebraska for the past 21 years. They had seen a doctor there during the summer time who prescribed her Seroquel and Lexapro, Thinking these were sx of a mood disorder. However, the medications did not help and she continued to deteriorate clinically.

Up until about 6 years ago, the pt worked at Tyson foods where she worked on the assembly line, slaughtering cattle and preparing them for packaging. She was exposed to brain and spinal cord matter when she would euthanize the cattle. The husband says that he does not know any fellow workers with a similar illness. He also says that she did not have any preceeding illness or travel.

Terry S. Singeltary Sr. has added the following comment:

"According to the World Health Organisation, the future public health threat of vCJD in the UK and Europe and potentially the rest of the world is of concern and currently unquantifiable. However, the possibility of a significant and geographically diverse vCJD epidemic occurring over the next few decades cannot be dismissed .

The key word here is diverse. What does diverse mean?

If USA scrapie transmitted to USA bovine does not produce pathology as the UK c-BSE, then why would CJD from there look like UK vCJD?"

.57 The experiment which might have determined whether BSE and scrapie were caused by the same agent (ie, the feeding of natural scrapie to cattle) was never undertaken in the UK. It was, however, performed in the USA in 1979, when it was shown that cattle inoculated with the scrapie agent endemic in the flock of Suffolk sheep at the United States Department of Agriculture in Mission, Texas, developed a TSE quite unlike BSE. 32 The findings of the initial transmission, though not of the clinical or neurohistological examination, were communicated in October 1988 to Dr Watson, Director of the CVL, following a visit by Dr Wrathall, one of the project leaders in the Pathology Department of the CVL, to the United States Department of Agriculture. 33 The results were not published at this point, since the attempted transmission to mice from the experimental cow brain had been inconclusive. The results of the clinical and histological differences between scrapie-affected sheep and cattle were published in 1995. Similar studies in which cattle were inoculated intracerebrally with scrapie inocula derived from a number of scrapie-affected sheep of different breeds and from different States, were carried out at the US National Animal Disease Centre. 34 The results, published in 1994, showed that this source of scrapie agent, though pathogenic for cattle, did not produce the same clinical signs of brain lesions characteristic of BSE.

REPORT ON THE INVESTIGATION OF THE SEVENTEENTH CASE OF BOVINE SPONGIFORM ENCEPHALOPATHY (BSE) IN CANADA

Greetings BSE-L et al,

I have sent off for a full report on the 17th case of BSE in Canada, and anymore cases since then. It now seems that the only way Canada is going to report their cases to the media, consumer, or the public, is if you ask, and be sure to be very explicit when you ask for whatever case you are referring too. I can't (well, I can) believe it's come to this. WE know the USA has systematically covered up mad cow disease in the USA (they just screwed up and got caught a couple of times), but this just seems to be acceptable now around the globe. But for Canada now to turn to these same type practices as the USDA, after such a long time of being up front with the consumer and the world on their Transmissible Spongiform Encephalopathy problems, I find it sad that this is what it has come to now. I had previously ask the CFIA for the ''16th case, and up'', and they only sent me the 16th case of mad cow disease. So I will await now to see if we get the full details on the 17th case of mad cow disease in Canada, and or the 18th case, and any more cases they might have found to date. I cannot believe either that this is what the OIE has let it come to be.

It says on the CFIA website ;

Comment 2006-2007 USA AND OIE POISONING GLOBE WITH BSE MRR POLICY

THE USA is in a most unique situation, one of unknown circumstances with human and animal TSE. THE USA has the most documented TSE in different species to date, with substrains growing in those species (BSE/BASE in cattle and CWD in deer and elk, there is evidence here with different strains), and we know that sheep scrapie has over 20 strains of the typical scrapie with atypical scrapie documented and also BSE is very likely to have passed to sheep. all of which have been rendered and fed back to animals for human and animal consumption, a frightening scenario. WE do not know the outcome, and to play with human life around the globe with the very likely TSE tainted products from the USA, in my opinion is like playing Russian roulette, of long duration, with potential long and enduring consequences, of which once done, cannot be undone. These are the facts as I have come to know through daily and extensive research of TSE over 9 years, since 12/14/97. I do not pretend to have all the answers, but i do know to continue to believe in the ukbsenvcjd only theory of transmission to humans of only this one strain from only this one TSE from only this one part of the globe, will only lead to further failures, and needless exposure to humans from all strains of TSE, and possibly many more needless deaths from TSE via a multitude of proven routes and sources via many studies with primates and rodents and other species.

MY personal belief, since you ask, is that not only the Canadian border, but the USA border, and the Mexican border should be sealed up tighter than a drum for exporting there TSE tainted products, until a validated, 100% sensitive test is available, and all animals for human and animal consumption are tested. all we are doing is the exact same thing the UK did with there mad cow poisoning when they exported it all over the globe, all the while knowing what they were doing. this BSE MRR policy is nothing more than a legal tool to do just exactly what the UK did, thanks to the OIE and GW, it's legal now. and they executed Saddam for poisoning ???

Subject: bse web siminar a joke


this was a farce. nothing substantial, it was as if we had gone back in time to 1997. they are oblivious. science totally outdated. totally a imported uk thing. feed ban has been in place in the usa and working well. still going by science that is outdated by a decade or more. i posted my question to them about 1 hour before webinar began on their site, and my question was not answered. it was confirmed as recieved. funny thing was, there mikes were left opened for about 30 minutes (interesting), 1 hour or so before the proceedigs began, and when it did begin, my name was on the pdf page as the first one, you could see it with the beginning of my greetings, however, my name was spelled wrong, and so i know they recieved the question i sent. my question was recieved and NOT answered, again. this also happened at the infamous 2001 BSE emergency conference call, where they refused to answer my question then as well...


The chat history has been cleared.

Terry S. Singeltary Sr. (Submitted question):

Good Afternoon Ladies and Gentlemen. Thank you for allowing me to pose my questions. With reference to Atypical BSE and BSE, all documented in North America, the total failure of the BSE feed ban, where it still fails in 2010, and total failure of the Enhanced BSE surveillance program of 2004, where even Dr. Paul Brown of the CDC, said that he did not trust anything from the USDA et al testing after the TEXAS MAD COW blunder in 2005, the fact that the h-BSE will transmit to humans (Kong et al 2009), and the fact that the l-BSE is far more virulent than the typical c-BSE, of which all three have been documented in North America, and the trading of live cattle, cattle by-products, and feed for cattle, between Canada, Mexico and the USA has been like swapping spit between two lovers, the fact that CJD is rising in the USA (if you look at the math from year to year totals), and that indeed unknown sporadic CJD phenotypes growing in the USA, with all this, my question is, HOW CAN you guarantee that the USA cattle and any product there from is BSE/TSE free from the USA ? The O.I.E. and it's regulations have failed us at every point in the BSE blunder. most every country that went by the O.I.E. B.S.E. guidelines all came down with BSE, and now the OIE/WAHO assumes that the human and animal health standards set out in the BSE chapter for classical BSE (C-Type) applies to all forms of BSE which include the H-type and L-type atypical forms. This assumption is scientifically not completely justified and accumulating evidence suggests that this may in fact not be the case. Molecular characterization and the spatial distribution pattern of histopathologic lesions and immunohistochemistry (IHC) signals are used to identify and characterize atypical BSE. Both the L-type and H-type atypical cases display significant differences in the conformation and spatial accumulation of the disease associated prion protein (PrPSc) in brains of afflicted cattle. Transmission studies in bovine transgenic and wild type mouse models support that the atypical BSE types might be unique strains because they have different incubation times and lesion profiles when compared to C-type BSE. When L-type BSE was inoculated into ovine transgenic mice and Syrian hamster the resulting molecular fingerprint had changed, either in the first or a subsequent passage, from L-type into C-type BSE. 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.

Greetings List Members,

I was lucky enough to sit in on this BSE conference call today and even managed to ask a question. that is when the trouble started.

I submitted a version of my notes to Sandra Blakeslee of the New York Times, whom seemed very upset, and rightly so.

"They tell me it is a closed meeting and they will release whatever information they deem fit. Rather infuriating."

and i would have been doing just fine, until i asked my question. i was surprised my time to ask a question so quick.

(understand, these are taken from my notes for now. the spelling of names and such could be off.)

[host Richard Barns] and now a question from Terry S. Singeltary of CJD Watch.

[TSS] yes, thank you, U.S. cattle, what kind of guarantee can you give for serum or tissue donor herds?

[no answer, you could hear in the back ground, mumbling and 'we can't. have him ask the question again.]

[host Richard] could you repeat the question?

[TSS] U.S. cattle, what kind of guarantee can you give for serum or tissue donor herds?

[not sure whom ask this] what group are you with?

[TSS] CJD Watch, my Mom died from hvCJD and we are tracking CJD world-wide.

[not sure who is speaking] could you please disconnect Mr. Singeltary

[TSS] you are not going to answer my question?

[not sure whom speaking] NO

from this point, i was still connected, got to listen and tape the whole conference. at one point someone came on, a woman, and ask again;

[unknown woman] what group are you with?

[TSS] CJD Watch and my Mom died from hvCJD we are trying to tract down CJD and other human TSE's world wide. i was invited to sit in on this from someone inside the USDA/APHIS and that is why i am here. do you intend on banning me from this conference now?

at this point the conference was turned back up, and i got to finish listening. They never answered or even addressed my one question, or even addressed the issue. BUT, i will try and give you a run-down for now, of the conference.

IF i were another Country, I would take heed to my notes, BUT PLEASE do not depend on them. ask for transcript from;

RBARNS@ORA.FDA.GOV 301-827-6906

he would be glad to give you one ;-)

Rockville Maryland, Richard Barns Host

BSE issues in the U.S., How they were labelling ruminant feed? Revising issues.

The conference opened up with the explaining of the U.K. BSE epidemic winding down with about 30 cases a week.

although new cases in other countries were now appearing.

Look at Germany whom said NO BSE and now have BSE.

BSE increasing across Europe.

Because of Temporary Ban on certain rendered product, heightened interest in U.S.

A recent statement in Washington Post, said the New Administration (old GW) has a list of issues. BSE is one of the issues.

BSE Risk is still low, minimal in U.S. with a greater interest in MBM not to enter U.S.

HOWEVER, if BSE were to enter the U.S. it would be economically disastrous to the render, feed, cattle, industries, and for human health.

(human health-they just threw that in cause i was listening. I will now jot down some figures in which they told you, 'no need to write them down'. just hope i have them correct. hmmm, maybe i hope i don't ???)

80% inspection of rendering

*Problem-Complete coverage of rendering HAS NOT occurred.

sizeable number of 1st time FAILED INITIAL INSPECTION, have not been reinspected (70% to 80%).

Compliance critical, Compliance poor in U.K. and other European Firms.

Gloria Dunason Major Assignment 1998 goal TOTAL compliance. This _did not_ occur. Mixed level of compliance, depending on firm.

Rendering FDA license and NON FDA license

system in place for home rendering & feed 76% in compliance 79% cross contamination 21% DID NOT have system 92% record keeping less than 60% total compliance

279 inspectors 185 handling prohibited materials

Renderer at top of pyramid, significant part of compliance. 84% compliance

failed to have caution statement render 72% compliance & cross contamination caution statement on feed, 'DO NOT FEED TO CATTLE'

56 FIRMS NEVER INSPECTED

1240 FDA license feed mills 846 inspected

"close to 400 feed mills have not been inspected"

80% compliance for feed.

10% don't have system.

NON-FDA licensed mills There is NO inventory on non licensed mills. approximately 6000 to 8000 Firms ??? 4,344 ever inspected. "FDA does not have a lot of experience with"

40% do NOT have caution statement 'DO NOT FEED'.

74% Commingling compliance

"This industry needs a lot of work and only half gotten to"

"700 Firms that were falitive, and need to be re-inspected, in addition to the 8,000 Firms."

Quote to do BSE inspection in 19 states by end of January or 30 days, and other states 60 days. to change feed status??? Contract check and ask questions and pass info.

At this time, we will take questions.

[I was about the third or fourth to ask question. then all B.S.eee broke loose, and i lost my train of thought for a few minutes. picked back up here]

someone asking about nutritional supplements and sourcing, did not get name. something about inspectors not knowing of BSE risk??? the conference person assuring that Steve Follum? and the TSE advisory Committee were handling that.

Some other Dr. Vet, whom were asking questions that did not know what to do???

[Dennis Wilson] California Food Agr. Imports, are they looking at imports?

[Conference person] they are looking at imports, FDA issued imports Bulletin.

[Linda Singeltary ??? this was a another phone in question, not related i don't think] Why do we have non-licensed facilities?

(conference person) other feed mills do not handle as potent drugs???

Dennis Blank, Ken Jackson licensed 400 non FDA 4400 inspected of a total of 6000 to 8000,

(they really don't know how many non licensed Firms in U.S. they guess 6000 to 8000??? TSS)

Linda Detwiler asking everyone (me) not to use emergency BSE number, unless last resort. (i thought of calling them today, and reporting the whole damn U.S. cattle herd ;-) 'not'

Warren-Maryland Dept. Agr. Prudent to re-inspect after 3 years. concerned of Firms that have changed owners.

hi sandy,

From the New York Times NYTimes.com, January 11, 2001

Many Makers of Feed Fail to Heed Rules on Mad Cow Disease By SANDRA BLAKESLEE

Large numbers of companies involved in manufacturing animal feed are not complying with regulations meant to prevent the emergence and spread of mad cow disease in the United States, the Food and Drug Administration said yesterday.

The widespread failure of companies to follow the regulations, adopted in August 1997, does not mean that the American food supply is unsafe, Dr. Stephen Sundlof, director of the Center for Veterinary Medicine at the F.D.A., said in an interview.

But much more needs to be done to ensure that mad cow disease does not arise in this country, Dr. Sundlof said.

The regulations state that feed manufacturers and companies that render slaughtered animals into useful products generally may not feed mammals to cud-chewing animals, or ruminants, which can carry mad cow disease.

All products that contain rendered cattle or sheep must have a label that says, "Do not feed to ruminants," Dr. Sundlof said. Manufacturers must also have a system to prevent ruminant products from being commingled with other rendered material like that from chicken, fish or pork. Finally, all companies must keep records of where their products originated and where they were sold.

Under the regulations, F.D.A. district offices and state veterinary offices were required to inspect all rendering plants and feed mills to make sure companies complied. But results issued yesterday demonstrate that more than three years later, different segments of the feed industry show varying levels of compliance.

Among 180 large companies that render cattle and another ruminant, sheep, nearly a quarter were not properly labeling their products and did not have a system to prevent commingling, the F.D.A. said. And among 347 F.D.A.-licensed feed mills that handle ruminant materials - these tend to be large operators that mix drugs into their products - 20 percent were not using labels with the required caution statement, and 25 percent did not have a system to prevent commingling.

Then there are some 6,000 to 8,000 feed mills so small they do not require F.D.A. licenses. They are nonetheless subject to the regulations, and of 1,593 small feed producers that handle ruminant material and have been inspected, 40 percent were not using approved labels and 25 percent had no system in place to prevent commingling.

On the other hand, fewer than 10 percent of companies, big and small, were failing to comply with the record-keeping regulations.

The American Feed Industry Association in Arlington, Va., did not return phone calls seeking comment.

######### Bovine Spongiform Encephalopathy #########


USDA/APHIS would like to provide clarification on the following point from Mr. Singeltary's 9 Jan posting regarding the 50 state conference call.

[Linda Detwiler asking everyone (me) not to use emergency BSE number, unless last resort. (i thought of calling them today, and reporting the whole damn U.S. cattle herd ;-) 'not']

Dr. Detwiler was responding to an announcement made during the call to use the FDA emergency number if anyone wanted to report a cow with signs suspect for BSE. Mr. Singeltary is correct that Dr. Detwiler asked participants to use the FDA emergency number as a last resort to report cattle suspect for BSE. What Mr. Singeltary failed to do was provide the List with Dr. Detwiler's entire statement. Surveillance for BSE in the United States is a cooperative effort between states, producers, private veterinarians, veterinary hospitals and the USDA. The system has been in place for over 10 years. Each state has a system in place wherein cases are reported to either the State Veterinarian, the federal Veterinarian in Charge or through the veterinary diagnostic laboratory system. The states also have provisions with emergency numbers. Dr. Detwiler asked participants to use the systems currently in place to avoid the possibility of a BSE-suspect report falling through the cracks. Use of the FDA emergency number has not been established as a means to report diseased cattle of any nature.

Hello Mr. Thomas,

What Mr. Singeltary failed to do was provide the List with Dr. Detwiler's entire statement.

would you and the USDA/APHIS be so kind as to supply this list with a full text version of the conference call and or post on your web-site? if so when, and thank you. if not, why not?

The system has been in place for over 10 years.

that seems to be a very long time for a system to be in place, and only test 10,700 cattle from some 1.5 BILLION head (including calf crop). Especially since French are testing some 20,000 weekly and the E.U. as a whole, are testing many many more than the U.S., with less cattle, same risk of BSE/TSEs.

Why does the U.S. insist on not doing massive testing with the tests which the E.U. are using? Why is this, please explain?

Please tell me why my question was not answered?

U.S. cattle, what kind of guarantee can you give for serum or tissue donor herds?

It was a very simple question, a very important question, one that pertained to the topic of BSE/feed, and asked in a very diplomatic way. why was it not answered?

If all these years, we have been hearing that pharmaceutical grade bovines were raised for pharmaceuticals vaccines etc. But yet the USA cannot comply with feed regulations of the ruminant feed ban, PLUS cannot even comply with the proper labelling of the feed, cross contamination etc. Then how in the world can you Guarantee the feed fed to pharmaceutical grade bovine, were actually non ruminant feed?

Before i was ask to be 'disconnected', i did hear someone in the background say 'we can't'-- have him ask the question again.

could you please be so kind, as to answer these questions?

thank you, Terry S. Singeltary Sr. Bacliff, Texas USA

P.S. if you will also notice, i did not post that emergency phone number and do not intend on passing it on to anyone. I was joking when i said i should call and report the whole damn U.S. Herd. So please pass that on to Dr. Detwiler, so she can rest easily.

BUT, they should be reported, some are infected with TSE. The U.S. is just acting as stupid as Germany and other Countries that insist they are free of BSE.

BUT no way were they gonna make the same mistake and allow me to ask a question or questions again, i did have more than one, or many others, there were not but 3 or 4 questions ask, that they allowed, and the audio was so bad you could not hear anything. so, now i have been through 3 Presidents, and 12+ years of this BSe, and nothing seems to have changed, it's all about the almighty dollar, to hell with human health.

Subject: USDA OIG SEMIANNUAL REPORT TO CONGRESS FY 2007 1st Half (bogus BSE sampling FROM HEALTHY USDA CATTLE) Date: June 21, 2007 at 2:49 pm PST

Owner and Corporation Plead Guilty to Defrauding Bovine Spongiform Encephalopathy (BSE) Surveillance Program

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.

snip...

Topics that will be covered in ongoing or planned reviews under Goal 1 include:

soundness of BSE maintenance sampling (APHIS),

implementation of Performance-Based Inspection System enhancements for specified risk material (SRM) violations and improved inspection controls over SRMs (FSIS and APHIS),

snip...

The findings and recommendations from these efforts will be covered in future semiannual reports as the relevant audits and investigations are completed.

4 USDA OIG SEMIANNUAL REPORT TO CONGRESS FY 2007 1st Half

-MORE Office of the United States Attorney District of Arizona FOR IMMEDIATE RELEASE For Information Contact Public Affairs February 16, 2007 WYN HORNBUCKLE Telephone: (602) 514-7625 Cell: (602) 525-2681

CORPORATION AND ITS PRESIDENT PLEAD GUILTY TO DEFRAUDING GOVERNMENT’S MAD COW DISEASE SURVEILLANCE PROGRAM

PHOENIX -- Farm Fresh Meats, Inc. and Roland Emerson Farabee, 55, of Maricopa, Arizona, pleaded guilty to stealing $390,000 in government funds, mail fraud and wire fraud, in federal district court in Phoenix. U.S. Attorney Daniel Knauss stated, “The integrity of the system that tests for mad cow disease relies upon the honest cooperation of enterprises like Farm Fresh Meats. Without that honest cooperation, consumers both in the U.S. and internationally are at risk. We want to thank the USDA’s Office of Inspector General for their continuing efforts to safeguard the public health and enforce the law.” Farm Fresh Meats and Farabee were charged by Information with theft of government funds, mail fraud and wire fraud. According to the Information, on June 7, 2004, Farabee, on behalf of Farm Fresh Meats, signed a contract with the U.S. Department of Agriculture (the “USDA Agreement”) to collect obex samples from cattle at high risk of mad cow disease (the “Targeted Cattle Population”). The Targeted Cattle Population consisted of the following cattle: cattle over thirty months of age; nonambulatory cattle; cattle exhibiting signs of central nervous system disorders; cattle exhibiting signs of mad cow disease; and dead cattle. Pursuant to the USDA Agreement, the USDA agreed to pay Farm Fresh Meats $150 per obex sample for collecting obex samples from cattle within the Targeted Cattle Population, and submitting the obex samples to a USDA laboratory for mad cow disease testing. Farm Fresh Meats further agreed to maintain in cold storage the sampled cattle carcasses and heads until the test results were received by Farm Fresh Meats.

Evidence uncovered during the government’s investigation established that Farm Fresh Meats and Farabee submitted samples from cattle outside the Targeted Cattle Population. Specifically, Farm Fresh Meats and Farabee submitted, or caused to be submitted, obex samples from healthy, USDA inspected cattle, in order to steal government moneys.

Evidence collected also demonstrated that Farm Fresh Meats and Farabee failed to maintain cattle carcasses and heads pending test results and falsified corporate books and records to conceal their malfeasance. Such actions, to the extent an obex sample tested positive (fortunately, none did), could have jeopardized the USDA’s ability to identify the diseased animal and pinpoint its place of origin. On Wednesday, February 14, 2007, Farm Fresh Meats and Farabee pleaded guilty to stealing government funds and using the mails and wires to effect the scheme. According to their guilty pleas:

(a) Farm Fresh Meats collected, and Farabee directed others to collect, obex samples from cattle outside the Targeted Cattle Population, which were not subject to payment by the USDA;

(b) Farm Fresh Meats 2 and Farabee caused to be submitted payment requests to the USDA knowing that the requests were based on obex samples that were not subject to payment under the USDA Agreement;

(c) Farm Fresh Meats completed and submitted, and Farabee directed others to complete and submit, BSE Surveillance Data Collection Forms to the USDA’s testing laboratory that were false and misleading;

(d) Farm Fresh Meats completed and submitted, and Farabee directed others to complete and submit, BSE Surveillance Submission Forms filed with the USDA that were false and misleading;

(e) Farm Fresh Meats falsified, and Farabee directed others to falsify, internal Farm Fresh Meats documents to conceal the fact that Farm Fresh Meats was seeking and obtaining payment from the USDA for obex samples obtained from cattle outside the Targeted Cattle Population; and

(f) Farm Fresh Meats failed to comply with, and Farabee directed others to fail to comply with, the USDA Agreement by discarding cattle carcasses and heads prior to receiving BSE test results. A conviction for theft of government funds carries a maximum penalty of 10 years imprisonment. Mail fraud and wire fraud convictions carry a maximum penalty of 20 years imprisonment. Convictions for the above referenced violations also carry a maximum fine of $250,000 for individuals and $500,000 for organizations. In determining an actual sentence, Judge Earl H. Carroll will consult the U.S. Sentencing Guidelines, which provide appropriate sentencing ranges. The judge, however, is not bound by those guidelines in determining a sentence.

Sentencing is set before Judge Earl H. Carroll on May 14, 2007. The investigation in this case was conducted by Assistant Special Agent in Charge Alejandro Quintero, United States Department of Agriculture, Office of Inspector General. The prosecution is being handled by Robert Long, Assistant U.S. Attorney, District of Arizona, Phoenix. CASE NUMBER: CR-07-00160-PHX-EHC RELEASE NUMBER: 2007-051(Farabee) # # #

Harvard BSE Risk Assessment


MY comments/questions are as follows ;

1. SINCE the first Harvard BSE Risk Assessment was so flawed and fraught with error after the PEER REVIEW assessment assessed this fact, how do you plan on stopping this from happening again, will there be another peer review with top TSE Scientist, an impartial jury so-to-speak, to assess this new and updated Harvard BSE/TSE risk assessment and will this assessment include the Atypical TSE and SRM issues ?
