Seventh Case of Mad Cow in Canada?

Another reason to avoid beef, or at least choose beef that is raised and slaughtered humanely.

Canada said it may have found its seventh case of mad cow disease, in a 50-month-old Alberta dairy animal born long after 1997 feed restrictions were imposed to curb the spread of the livestock ailment.

Authorities identified the cow through preliminary screenings. Confirmatory tests are being performed on tissue samples and results will be made public by the end of the week, said George Luterbach, a senior veterinarian with the Canadian Food Inspection Agency. No part of the animal entered the human or animal food or feed chain, the agency said.
