they didn't ask her what she was mad about....... Mad cow found in Alabama Associated Press WASHINGTON - A cow in Alabama has tested positive for mad-cow disease, the Agriculture Department said yesterday, confirming the third U.S. case of the brain-wasting ailment. The cow did not enter the food supply for people or animals, officials said. The animal, unable to walk, was killed by a local veterinarian and buried on the farm. "We remain very confident in the safety of U.S. beef," said the department's chief veterinarian, John Clifford. Authorities said the farm was under an informal quarantine but would not say where it was. "We will not release this information at this time until we complete our investigation, and that could take a few days," said Alabama Agriculture Commissioner Ron Sparks. The news came as the Bush administration worked to reassure Japan and other foreign customers of American beef. Japan halted U.S. beef shipments in January after finding veal cuts with backbone - cuts that are eaten in the U.S. but not in Asia.
