Mad cow disease found in Alberta cow

The Canadian Food Inspection Agency announced Tuesday the carcass of a lone dairy cow in Alberta tested positive for mad cow disease.

A news release issued in Edmonton said it was the 12th discovery of bovine spongiform encephalopathy in Canada since May 2003 but posed no risk to humans as none of the animal entered the human or animal food chains, the Edmonton Journal reported.

"Based on science, it is not expected that this case should impact access to any of Canada's current international markets for cattle and beef," the release said.

Nine of the confirmed Canadian BSE cases have been found in Alberta, the agency said.
