Test results have confirmed a case of BSE or mad-cow disease in Manitoba. The animal is at least 15 years old, which means that it was born before bans were imposed on the type of feed associated with BSE. Investigators are working to locate the animal's birth farm, which will help identify other herdmates that could have been exposed to the same feed. However, agency officials said that the investigation might be "constrained" by the animal's advanced age and a lack of detailed records after such a long time. A calf born to the animal in 2004 is being traced.
