U.S. Department of Agriculture officials acknowledged Friday that it could be weeks or months before they trace a diseased Holstein that tested positive for "mad cow" disease to its home herd. "There is a tangled web of different possibilities," said W. Ron DeHaven, the USDA's chief veterinarian. Agricultural detectives say a dairy farm near Mabton, Wash., purchased the cow from either a livestock market or another dairy farm in October 2001.

Tests for mad cow disease have come up negative in the case of an animal that died in April, the Agriculture Department said. Testing by the department's laboratory in Ames, Iowa, and the internationally recognized laboratory in Weybridge, England, found no evidence of the brain-wasting disease in the cow, said Dr. John Clifford, the department's chief veterinarian. "We are very pleased with these results," Clifford said in a statement.

Holstein calves killed as a precautionary measure against mad cow disease were buried Wednesday at a landfill, a disposal method that state officials said would protect the public from any possible health threat. A snowstorm had delayed federal officials' plans to bury the herd of 449 calves Wednesday, but by late afternoon two trucks containing the animals had pulled up to the southern Washington landfill.

The Brazilian beef industry and port workers are boycotting Canadian imports in a deepening dispute over Ottawa's decision to ban Brazilian beef on concerns about "mad cow" disease, cattle ranchers said Tuesday.

"Mad cow" disease is one of a small family of diseases that are like no others. The vast majority of infectious illnesses are caused by a virus or bacteria -- living organisms, or in the case of viruses, quasi-living organisms -- with their own genetic blueprint that allows them to invade the body and reproduce.

Disgruntled Vermont farmers went to court Wednesday in an attempt to prevent the U.S. Department of Agriculture from destroying their sheep because they may carry an ailment similar to "mad cow" disease in cattle. The USDA, which has been closely monitoring all American livestock since the 1996 outbreak of mad cow disease in Europe, wants to destroy sheep on three Vermont farms as a precaution.

The Agriculture Department is ending its search for additional cases of mad cow disease even though officials have not found several animals suspected of having eaten the potentially infectious feed believed to have caused the only known U.S. case. "Our investigation is now complete," W. Ron DeHaven, the department's chief veterinarian, said Monday. "We feel very confident the remaining animals, the ones we have not been able to positively identify, represent little risk."

Health and agriculture officials disclosed Friday that selective testing of beef cattle for so-called mad cow disease has turned up two infected animals from Germany, shocking this nation of food purists into action to demand an immediate ban on cattle feed containing animal parts and mandatory testing of older cows before slaughter.

For the last several months, a bizarre, miniaturized replay of the British mad cow crisis has gripped the United States. Except this time, there's been no cattle epidemic and no human victims. Just speculation, publicity, more speculation, more publicity. In part, the furor was triggered by our own regulators.
