Canada's mad cow case may
have come from US: inquiry

OTTAWA -- The origin of Canada's single case of mad cow disease may never be pinpointed, but investigators said in a report there is a possibility it came from the United States.

Some 25,000 pregnant cows were imported from the United States with missing identification before Canada banned animal-based feed in 1997, the Canadian Food Inspection Agency said in a report released late Wednesday.


"Although DNA investigations continue, Canada cannot, to date, exclude the possibility that the index case itself derived through this huge, unique importation."

The cows were imported to the western Canada region where the country's only reported case of mad cow disease was discovered in a Black Angus cow.

"Of these, 70-80 percent were described as being of the Black Angus breed," the report said.

On May 20, the cow, which was slaughtered in Alberta in January, was confirmed to have had mad cow disease, or bovine spongiform encephalopathy (BSE).

The United States, Canada's biggest beef export market, immediately banned Canadian beef products even though the BSE-infected animal had never entered the human food chain.

Since then, Canadian investigators have slaughtered for testing more than 2,000 cattle and had found no evidence of another case of mad cow disease.

"The possibility of the US being the origin of the index case or the source of contaminated feed remains among the multiple avenues of continuing study, and might be best defined by ongoing surveillance being conducted in the US," the report said.

Last month, an international panel investigating the single case of mad cow disease in Canada reported that it likely came from "exposure to infective material through the feeding system."

If the birthplace of this afflicted cow was definitively determined to be in North America, it could become the continent's first home-grown case of the disease.

In 1993, there was one case of mad cow disease in Canada, but it was a cow imported from Britain, where the disease first appeared in 1986.
