Mad cow detected in Alberta bull
VANCOUVER, British Columbia (Reuters) - Tests have confirmed mad cow disease in a mature bull in Alberta, but none of the animal entered the food chain, the Canadian Food Inspection Agency said on Wednesday.
"The animal's carcass is under CFIA control, and no part of it entered the human food or animal feed systems," the agency said in a statement.
The agency did not say how old the animal was, but said that based on preliminary information it was "within the age range" of other Canadian cattle found to have have been infected with the disease.
"This signifies that the animal was exposed to a very small amount of infective material, most likely during its first year of life," CFIA said in a statement.
