France today announced a ban on all imports of British beef to protect against an outbreak of "mad cow" disease that has killed thousands of British cattle. Agriculture Minister Henri Nallet said the ban, to take effect Thursday, will be lifted as soon as Paris is convinced that the British virus poses no danger to French citizens. Austria imposed a similar ban Tuesday.

DNA tests have confirmed that the Holstein found last month to be infected with mad cow disease originated in Alberta, Canada, U.S. Department of Agriculture officials said Tuesday. The DNA testing on the cow and her offspring, as well as earlier-reported records showing that the cow had been sold by an Alberta farmer disposing of his dairy herd, "makes us confident in the accuracy of this trace-back," said W. Ron DeHaven, the department's chief veterinarian.

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.

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. The Brazilian Rural Society, representing hundreds of thousands of small farmers including 70,000 cattle ranchers, said it was suspending imports of potassium chloride, used in fertilizers and one of Canada's chief exports to Brazil.

"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. Mad cow disease apparently is not.

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."

Five bulls from a Canadian herd that included a cow with "mad-cow" disease were shipped to Montana six years ago and have since been slaughtered, state officials said Wednesday. None of the animals showed clinical signs of the disease, said Karen Cooper, spokeswoman for the Montana Department of Livestock. What became of the carcasses after the bulls were killed was unclear.
