Canada has reported a new case of mad cow disease on Tuesday, saying it originated from a six-year-old dairy cow in Alberta. The Canadian Food Inspection Agency confirms this is the 12th case since 2003.

George Luterbach, a senior veterinarian with the agency, described the cow, according to Calgary Herald, as thin and weak and with deteriorating health causing it to collapse ten days ago in its farm located in Edmonton, Alberta.

Meanwhile, the Animal and Plant Health Inspection Service in Maryland maintained that the latest case of mad cow disease in Alberta is an isolated one and does not affect any international policy on cattle export.

The inspection agency affirmed the association's statement, saying Canada has kept its controlled-risk security ratings, earlier attested by the World Organization for Animal Health. With this status, the inspection agency reiterated, that Canada can still send its cattle and beef to any of the country's international markets.

Luterbach assured the public that CFIA will continue with its investigation by tracking down of other cows born of the same age of the six-year-old infected cow from Edmonton farm.

The official also said that the inspection agency will also investigation on feed supply tracking down records from 2001.
