Mad cow disease case called atypical
An atypical case of mad cow disease was found Tuesday in Alabama at a state livestock market, according to the U.S. Department of Agriculture. Authorities reportedly found the 11-year-old cow exhibiting clinical signs of the disease before it went to slaughter.
“The animal never entered slaughter channels and at no time presented a risk to the food supply, or to human health in the United States,” according to a news release.
This is the fifth reported case of bovine spongiform encephalopathy in the U.S. The previous three reported cases also were considered atypical, or L-type, different from the classic form, H-type, contracted by eating contaminated protein from infected cattle.
The USDA’s Animal and Plant Health Inspection Service and Alabama veterinary officials are gathering further information on Tuesday’s case.
