U.S. Checking Possible New Case of Mad Cow

WASHINGTON - The government is checking a possible case of mad cow disease, the Agriculture Department said Friday.

The suspected case, in a beef cow, had tested negative for mad cow disease. Initial tests have shown the disease three times since an infected cow turned up in December 2003 in Washington state. The department decided this week to perform additional tests, and one of the three turned up positive.

The sample is being subjected to additional tests, the department said.

"It's going to require additional testing before we can confirm one way or another whether this is
BSE (mad cow disease)," said Dr. John Clifford, chief veterinary officer of the department's Animal and Plant Health Inspection Service.
