A Riverside, Calif. neurologist lost a patient to CJD last year and thinks something is fishy at NPDPSC, the US prion watchdog agency. Allegedly the agency ruled out mad cow based on a test not acceptable to neuropathology experts. Now they've "lost" the brain sample and aren't talking to reporters. Now six cows from an infected Canadian herd have disappeared in the U.S. beef supply without a trace. The USDA doesn't seem to be talking to reporters, either.
