BSE case in B.C. likely came from feed

The Canada Food Inspection Agency says a B.C. feed manufacturer is the most likely source of the country's 13th case of mad cow disease.

In a report, the Agency said that one of the most recent cases of BSE and all 12 previous cases likely came "through incidents of accidental cross-contamination, which may occur in the complex feed and manufacturing system."

Because the incubation period is four to six years, officials belief the animal was contaminated as a calf. The food source was narrowed down to an unnamed food supplier of heifer ration that also manufactured food for other, non-ruminant animals that contained material prohibited from cattle, sheep and goat feed.

Two other unnamed feed manufacturers where prohibited material was handled were also mentioned in the report as potential areas for cross-contamination. The report said the feed did not contained banned protein on purpose, but may have been contaminated by equipment used to process non-ruminant feed. "Bulk ingredient receiving and finished feed conveyances were cross-utilized," the report said.

The agency said a total of 207 other animals connected to the diseased cow either have been or will be destroyed. "The detection of this case does not change any of Canada's BSE risk parameters," the report concluded. "The location and age of the animal are consistent with previous cases."
