US BSE outbreak 'traced to Canada'

Investigators tentatively traced the first US case of “mad cow disease” to Canada, which could help determine the scope of the outbreak and might even limit the economic damage to the country’s beef industry.

In addition, some calves in a quarantined herd of 400 that included a male offspring of the sick cow will probably be destroyed, the US Agriculture Department said yesterday. The herd was at a farm in Sunnyside, Washington.
