WASHINGTON (AP) — The Agriculture Department says there's no cause for alarm after a new case of mad cow disease surfaced in a dairy cow in Central California.The department's chief veterinary officer John Clifford says the animal wasn't bound for the nation's food chain and posed no danger. It's the fourth such cow discovered in the United States since the government began inspecting for the disease to keep the food supply safe.Clifford did not say when the disease was discovered or exactly where the cow was raised. He said the cow was at a rendering plant in Central California when the case was discovered through regular USDA sample testing.Clifford said the cow is an atypical case in that it didn't get the disease from eating infected cattle feed.The World Health Organization has said that tests show humans can't be infected by drinking milk from infected animals.
