Formally known as Bovine Spongiform Encephalopathy (BSE), “Mad Cow Disease” is a persistent food safety concern in the U.S. and abroad. BSE occurs when cattle are fed rendered meat products made from other dead, disabled or diseased cattle or sheep as a feed supplement -- or when chickens are fed rendered animals and their manure is mixed into cattle feed.
