FDA Proposes Barring Certain
Cattle Material From Medical 
Products As BSE Safeguard

From Patricia Doyle, PhD
1-30-7

(Note - The problem of mad cow in medical products (and elsewhere) is obviously severe. The FDA should have done this 10-12 years ago. I have been cautioning and warning (with Dr. Patricia Doyle, PhD) about this very real danger for over 10 years now. The measures below don't go nearly far enough. Example of the half-baked 'logic' of these new 'restrictions': ".... that would bar material that has been found to harbor the highest concentrations of this fatal agent in infected cattle."This is outrageous. So, the FDA is saying that cattle parts with slightly less than the 'highest (whatever that actually means) concentrations' of mad cow prions are OK TO KEEP ON USING. How many prions does one have to ingest to develop mad cow and die a hideous death? ONE, until proven otherwise. - Jeff Rense)
 
 
The U.S. Food and Drug Administration is proposing to limit the materials used in some medical products in order to keep them free of the agent thought to cause mad cow disease, also known as bovine spongiform encephalopathy or BSE.
 
This is the latest in a series of BSE safeguards that would bar material that has been found to harbor the highest concentrations of this fatal agent in infected cattle. These materials would be prohibited from use as ingredients in medical products or elements of product manufacturing.
 
The proposed rule would cover drugs (prescription, over-the-counter, and homeopathic), biologics (such as vaccines) and medical devices intended for use in humans as well as drugs intended for use in ruminant animals like cattle and sheep. Cattle can get mad cow disease, while sheep can get a similar disease known as scrapie.
 
"These measures build on a series of barriers FDA and the U.S. Department of Agriculture have erected to further protect humans from exposure to the fatal agent linked to BSE," said Andrew von Eschenbach, M.D., Commissioner Food and Drugs. "This proposed rule adds one more safeguard that will reduce the risk of transmission even further."
 
The cattle materials prohibited in the proposed rule are those that pose the highest risk of containing infectious material and include: 
 
-- the brain, skull, eyes and spinal cords from cattle 30 months and older; 
 
-- the tonsils and a portion of the small intestines from all cattle regardless of their age or health; 
 
-- any material from "downer" cattle--those that cannot walk; 
 
-- any material from cattle not inspected and passed for human consumption; 
 
-- fetal calf serum if appropriate procedures have not been followed to prevent its contamination with materials prohibited by this proposed rule; 
 
-- tallow that contains more than 0.15 percent insoluble impurities if the tallow is derived from materials prohibited by this proposed rule and; 
 
-- mechanically separated beef.
 
To ensure that companies comply with these prohibitions, FDA proposes to require that records be kept to demonstrate that any cattle material used as an ingredient in these medical products or as part of their manufacturing process meet the rule's requirements.
 
Since 1996, strong evidence has accumulated for a causal relationship between ongoing outbreaks of mad cow disease in Europe and a disease in humans called variant Creutzfeldt-Jakob (vCJD) disease. Both disorders, which are thought to be caused by an unconventional transmissible agent, are invariably fatal brain diseases with incubation periods typically measured in years. Transmission of the BSE agent to humans, leading to vCJD, is believed to occur via ingestion of cattle products contaminated with the BSE agent; however the specific products associated with this transmission are unknown.
 
About 200 cases of vCJD have been identified worldwide, including three cases in the U.S. However, there is no evidence that those three patients contracted the BSE agent in the U.S.
 
FDA and USDA's efforts to help protect the public from vCJD have included several other significant steps such as the FDA's 1997 ruminant feed regulation, which forbids the use of certain mammalian-origin proteins in ruminant feed. Also, a 2005 interim final rule bans the use of certain high-risk cattle material in food, dietary supplements and cosmetics.
