Agency Name Food & Drug Administration Description
1. Research Objectives The Food and Drug Administration (FDA), Office of Regulatory Affairs (ORA), Division of Federal-State Relations (DFSR) in coordination with the Center for Veterinary Medicine (CVM), is announcing the availability of cooperative agreements to further enhance the infrastructure of State, territorial, and tribal animal feed safety and bovine spongiform encephalopathy (BSE) prevention programs. These cooperative agreements are intended to fund additional personnel, equipment, supplies, and training to support activities related to the FDA ruminant feed ban (21 CFR parts 589.2000 - 2001, referred to as the BSE/ruminant feed ban) as well as other activities related to feed safety, in State, territory, and tribal governments. The goal of FDA’s ORA Cooperative Agreement Program is to enhance, complement, develop and improve State/territory/tribal animal feed safety and surveillance programs. This will be accomplished through the provision of funding for additional equipment, supplies, funding for personnel, training in current feed testing methodologies recognized by FDA, participation in proficiency testing to establish additional reliable laboratory sample analysis capacity, and analysis of surveillance samples as well as State/territorial/tribal government compliance inspections. This will also require extensive cooperation and coordination with FDA District Offices to minimize duplication of inspections. Under these cooperative agreements, the State, territory, and tribal governments would enhance their feed safety and/or BSE/ruminant feed ban programs to increase the ability to locate and visit firms involved in the manufacture, distribution, and transportation of animal feed and operations feeding livestock in their jurisdiction. Verification of compliance with the BSE/ruminant feed ban as well as other regulations related to feed safety will be conducted. In addition, funds could be used to increase State, territory, and tribal personnel dedicated to conducting these inspections. Funds could be used for supplies, training, and laboratory equipment for feed sample testing using analytical methods recognized by FDA. Funds could also be used to conduct educational outreach activities and to develop materials needed to further and enhance the industries' knowledge of and compliance with feed safety regulations and the BSE/ruminant feed ban. As a result of enhancing their feed safety and/or BSE/ruminant feed ban programs, an increase in State, territory, and tribal inspections under section 702 of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 372) of renderers, protein blenders, feed mills that manufacture animal feeds, feed ingredient manufacturers, feed distributors an d transporters, salvagers of food and feed, and livestock feeders is expected. Animal feed and feed ingredients utilizing materials prohibited under the BSE/ruminant feed ban are of significant interest, although other work related to feed safety may also be conducted. Finally, the Feed Safety and BSE/Ruminant Feed Ban Support Project funds are intended to supplement, not replace, State funding for program improvement. All cooperative agreement projects that are developed at State, territorial, and tribal levels must have existing feed inspection and surveillance programs or propose in detail the development of a State/territory/tribal feed regulatory program. There are eight key project areas identified for this effort that must be addressed: (1) Hire and/or train State/territory/tribal personnel to conduct inspections. Training of State/territory/tribal personnel may be accomplished through the ORA University, training sponsored by the Association of American Feed Control Officials, or other training that meets State/territory/tribal and FDA requirements. New hires for this program must meet the State/territory/tribal agency’s qualifications for feed inspections and sampling techniques. (2) Hire and/or train laboratory personnel to conduct laboratory analyses of fe d samples. Laboratory analyses of samples collecte under this program must utilize methodologies recognized by the FDA, or other professional groups, such as the Association of Official Analytical Chemists International (AOACI). (3) Identify animal feed and feed ingredient manufacturers, including renderers, protein blenders, feed mills, ingredient manufacturers, feed salvagers, distributors (including retailers), transporters of animal feed and feed ingredients, and on-farm animal feed mixers, as well as ruminant feeders within the State/territory/tribal jurisdiction where such firms have not already been identified and/or inspected for compliance with feed safety requirements, such as the BSE/ruminant feed ban. (4) Inspect animal feed and feed ingredient manufacturers, including renderers, protein blenders, feed mills, ingredient manufacturers, feed salvagers, distributors (including retailers), transporters of animal feed and feed ingredients, and on-farm animal feed mixers, as well as ruminant feeders within the State/territory/tribal jurisdiction where such firms have not already been identified and/or inspected for compliance with feed safety requirements, such as the BSE/ruminant feed ban. These inspections would be conducted under section 702 of the FD&C Act, using and completing the appropriate inspection forms and following the appropriate guidance to verify compliance. For example, the FDA Ruminant Feed Ban Inspection Checklist and Ruminant Feed Ban Compliance Program would be used to verify compliance with the BSE/ruminant feed ban. These inspections would be conducted by officers and employees duly commissioned by FDA in accordance with section 702 of the FD&C Act. (5) Conduct surveillance sampling at establishments supplying ingredients or finished feed into the feed supply, including manufacturers, distributors, and livestock feeders. Samples should be tested for the presence of materials prohibited under the BSE/ruminant feed ban or other contaminants, such as drug and pesticide residues, mycotoxins, heavy metals or the presence of pathogenic microorganisms. This surveillance sampling would be conducted under section 702 of the FD&C Act and would be conducted by officers and employees duly commissioned by FDA in accor dance with section 702 of the FD&C Act. (6) Provide copies of all completed inspection reports, including any FDA Ruminant Feed Ban Inspection Checklists, analytical results for surveillance sampling, and reports of any other inspection work as a part of the mid-year program progress report to the FDA Project officer or designated office, as well as provide completed checklists and sample results in accordance with section 702 of the FD&C Act. (7) Be able to identify and quantify improvements to the existing State/territory/tribal feed safety and/or BSE/ruminant feed ban program or developing new programs (i.e., personnel hiring, personnel training, equipment upgrades, increase in inspections conducted) in the mi d-year report as a result of the cooperative agreement. (8) Conduct educational outreach activities and develop materials needed to further and enhance the industries' knowledge of and compliance with feed safety requirements, such as but not limited to the BSE/ruminant feed ban and medicated feed good manufacturing practice regulations, for example. FDA will support the projects covered by this notice under the authority of section 311 of the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 (the Bioterrorism Act) (Public Law 107-188), which amends the FD&C Act by adding section 909 (21 U.S.C. 399). This program is described in the Catalog of Federal Domestic Assistance under number 93.449.

Feed Safety and BSE/Ruminant Feed Ban Support Project (U18)
FOR IMMEDIATE RELEASE September 14, 2010
AGRICULTURE DEPARTMENT RECEIVES FEDERAL FUNDING TO PREVENT MAD COW DISEASE FDA cooperative agreement helps Illinois maintain food and feed inspections SPRINGFIELD, Ill. - The Illinois Department of Agriculture (IDOA) will receive more than a million dollars in federal funding to conduct important inspections for bovine spongiform encephalopathy (BSE), otherwise known as mad cow disease.
The U.S. Food and Drug Administration (FDA) has entered into a cooperative agreement with the department that will provide a total of $1,244,960 over the next five years to ensure cattle feed produced and used in Illinois does not contain ingredients that could transmit the rare brain-wasting disease. Illinois was one of twelve states to receive federal funding in this cooperative agreement.
"For nearly 20 years, our inspectors have been contracted by the FDA to inspect feed mills and feed manufacturing plants across the state," Agriculture Director Tom Jennings said. "But this agreement will allow us to maintain our expanded on-farm surveillance efforts. We believe these inspections provide additional assurance to consumers and our agricultural trading partners that Illinois beef is safe to eat."
Feed contaminated with tissue from the nervous system of infected cattle is believed to spread BSE. Therefore, the FDA has prohibited the use of ruminant protein in feed for cattle and other ruminant animals since 1997. The department enforces this prohibition in Illinois through regular inspections.
Over the past two years under a similar agreement, IDOA completed 300 on-farm inspections and 100 non-farm inspections. More than 1,000 cattle feed samples were collected and analyzed.
I suppose we have to give them E for effort. course it's like closing the barn doors after the mad cows got loose. ...TSS
Molecular characterization of BSE in Canada
Jianmin Yang1, Sandor Dudas2, Catherine Graham2, Markus Czub3, Tim McAllister1, Stefanie Czub1 1Agriculture and Agri-Food Canada Research Centre, Canada; 2National and OIE BSE Reference Laboratory, Canada; 3University of Calgary, Canada
Background: Three BSE types (classical and two atypical) have been identified on the basis of molecular characteristics of the misfolded protein associated with the disease. To date, each of these three types have been detected in Canadian cattle.
Objectives: This study was conducted to further characterize the 16 Canadian BSE cases based on the biochemical properties of there associated PrPres. Methods: Immuno-reactivity, molecular weight, glycoform profiles and relative proteinase K sensitivity of the PrPres from each of the 16 confirmed Canadian BSE cases was determined using modified Western blot analysis.
Results: Fourteen of the 16 Canadian BSE cases were C type, 1 was H type and 1 was L type. The Canadian H and L-type BSE cases exhibited size shifts and changes in glycosylation similar to other atypical BSE cases. PK digestion under mild and stringent conditions revealed a reduced protease resistance of the atypical cases compared to the C-type cases. N terminal- specific antibodies bound to PrPres from H type but not from C or L type. The C-terminal-specific antibodies resulted in a shift in the glycoform profile and detected a fourth band in the Canadian H-type BSE.
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.
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.......$$$

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.
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.

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

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

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.

Variant Creutzfeldt–Jakob disease (vCJD) has been recognized to date only in individuals homozygous for methionine at PRNP codon 129. Here we show that transgenic mice expressing human PrP methionine 129, inoculated with either bovine spongiform encephalopathy (BSE) or variant CJD prions, may develop the neuropathological and molecular phenotype of vCJD, consistent with these diseases being caused by the same prion strain. Surprisingly, however, BSE transmission to these transgenic mice, in addition to producing a vCJD-like phenotype, can also result in a distinct molecular phenotype that is indistinguishable from that of sporadic CJD with PrPSc type 2. These data suggest that more than one BSE-derived prion strain might infect humans; it is therefore possible that some patients with a phenotype consistent with sporadic CJD may have a disease arising from BSE exposure.

To minimise the risk of farmers' claims for compensation from feed compounders.
To minimise the potential damage to compound feed markets through adverse publicity.
To maximise freedom of action for feed compounders, notably by maintaining the availability of meat and bone meal as a raw material in animal feeds, and ensuring time is available to make any changes which may be required.
MAFF remains under pressure in Brussels and is not skilled at handling potentially explosive issues.
5. Tests _may_ show that ruminant feeds have been sold which contain illegal traces of ruminant protein. More likely, a few positive test results will turn up but proof that a particular feed mill knowingly supplied it to a particular farm will be difficult if not impossible.
6. The threat remains real and it will be some years before feed compounders are free of it. The longer we can avoid any direct linkage between feed milling _practices_ and actual BSE cases, the more likely it is that serious damage can be avoided. ...
