OTTAWA (AP) _ The Canadian government has confirmed a new case of mad cow disease.

The Canadian Food Inspection Agency said Tuesday the brain wasting disease showed up in an Alberta cow under seven years old.

Officials say no part of the animal has entered the human or animal feed system. Agency officials were to hold a news conference Tuesday afternoon to discuss the new case, the second case of bovine spongiform encephalopathy found in Canada this year.

The age of the cow means it was born after a 1997 feed ban in Canada removed the use of ruminants in feed, commonly believed to be the cause of the disease. That could make the cause much more difficult to trace.
