The Canadian Food Inspection Agency has confirmed that a deceased mature dairy cow in British Columbia had bovine spongiform encephalopathy. No part of the cow entered human or animal food systems.
CFIA is launching an investigation to identify the other animals in the cow's herd at its time of birth. The animal appears to have died at 66 months, which would put it within the age range of previous BSE cases in Canada. This probably means the animal was exposed to infective material during its first year of life, after which the disease incubated inside the animal.
The World Organization for Animal Health has recommended Canada as a controlled risk country for BSE. Canada has taken measures to prevent additional BSE cases, but expects to uncover a small number of cases over the next decade as it works to eliminate the disease.
