The first cow in the U.S. to have a confirmed case of mad cow disease was on the Sunny Dene Ranch on Monday, Jan. 12, 2004.

A California dairy cow has been confirmed with a new case of mad cow disease, it was announced Tuesday. 

According to the Agriculture Department, the animal was not a danger to public health and was not headed for the nation's food supply. The department says U.S. meat and dairy supplies are safe.

At a quickly assembled press conference, John Clifford, the department's chief veterinary officer said, "There is really no cause for alarm here with regard to this animal." 

The sick cow, hailing from central CA, did not enter the food chain, officials assured. This is the fourth such diagnosis in the U.S. since the government began safety inspections.

It is unknown when the disease was discovered, or where exactly the cow was raised. Clifford said the case was discovered through regular USDA sample testing while the cow was at a rendering plant in Central California .
