Multiple strains of mad cow disease exist

April 18, 2008

A case of mad cow disease discovered in Canada in December involves an “atypical” (uncommon) strain of the infection also reported in Europe, Canadian officials said Wednesday.

Canada’s 11th case of bovine spongiform encephalopathy (BSE), also called mad cow disease, provides evidence that multiple strains of the affliction exist around the world, said the Canadian Food Inspection Agency.

“Canada’s eleventh case of BSE has been attributed to a less prevalent, atypical strain of BSE which has also been reported in Europe. This is the second case of BSE in Canada that has involved an atypical strain,” the CFIA said.
