Mad cow disease and Canada's cattle industry

26 Oct 2005

The discovery of a case of mad cow disease in Alberta in May 2003 – the second such case in Canada; the first dates back to 1993 – tested the measures introduced over the past decade to prevent the introduction and spread of the disease in Canada. [...] The paper also presents the results of the investigation following the discovery of the May 2003 case, as well as the measures that have been proposed to improve the existing system, and examines the North American aspect of the issue. [...] The last section discusses how the industry has been affected by the closing of the border to Canadian beef exports, and the possibility of reopening it. [...] Since the discovery of the first case of BSE in 1993, the number of tests administered each year, except for 1995, has surpassed the number recommended by the OIE.(7) Since the 1993 case, other measures have been put in place. [...] This policy includes the destruction of: • the herd in which a case is diagnosed; • the herd in which the diseased animal was born; • the birth cohort of the diseased animal; • animals with the same lineage (mother and descendants); and • embryos from the herds and animals involved.
