they banned (not that enforce the law) it from being used in cattle feed yet it's legal for us humans to eat potentially prion laden crap.
Health and Consumer Groups Urge USDA to Keep Cattle Spinal Cord Tissue Out of Processed Meathttp://www.cspinet.org/new/madcow_protection.html“While the Food and Drug Administration (FDA) in 1997 banned the use of processed cattle parts in making cattle feed, USDA has not taken adequate precautions to protect the human food supply,” said Smith DeWaal. “U.S. cattle aren’t allowed to eat cattle spinal cord — and neither should people.”
The CSPI petition urged USDA to ban cattle spinal columns and neck bones from processing through advanced meat recovery (AMR) machines. Those machines strip soft tissue (including meat and spinal cord) from bones and produce 40 million pounds of meat paste annually. That meat paste typically is used in the production of hundreds of millions of pounds of hot dogs, hamburgers, pizza toppings, and taco fillings. Although USDA has asked companies to remove spinal cord from the spinal column and neck bones before they enter the machines, the agency rarely checks the industry’s compliance. Since 1998, USDA has tested approximately 100 samples of AMR meat for spinal cord. Of those, nine samples tested positive for this central nervous system tissue.
CSPI also asked the Secretary to review all USDA regulations to determine what other food products might contain small amounts of brain tissue, central nervous system tissue, or other potentially infective materials from cattle and amend those regulations to ban potentially infectious materials from entering the food supply.
