The Canadian Food Inspection Agency (CFIA) is enhancing regulations to more quickly eliminate bovine spongiform encephalopathy (BSE), or mad cow disease, from Canada.

In infected cattle, BSE concentrates in certain tissues known as specified risk material (SRM). As a public health protection, these tissues are removed from all cattle slaughtered for human consumption. To limit BSE spread among cattle, the Government of Canada banned most proteins, including SRM, from cattle feed in 1997. To provide further animal health protection, as of July 12, 2007, SRM are also banned from all animal feeds, pet foods and fertilizers.


A permit is required for transporting and disposing of certain cattle tissues capable of transmitting BSE, known as SRM.
