First US mad-cow disease case in six years

A dairy cow in central California was diagnosed with bovine spongiform encephalopathy (BSE), also known as mad-cow disease, on Tuesday. This is the first U.S. case in six years, but U.S. authorities are saying the meat supply is not at risk. Many foreign importers of U.S. beef have accepted this claim, but S. Korea has halted sales of U.S. beef.

The risk of transmission from this cow is considered rare or unlikely, because this was an atypical case thought to have occurred spontaneously, and the cow was not destined to be slaughtered for food. Bovine spongiform encephalopathy is also not transmitted via milk.
