Specified risk material

Specified risk material (SRM) is any of various tissues of ruminant animals that cannot be inspected and passed for human food because scientists have determined that bovine spongiform encephalopathy (BSE)-causing prions concentrate there, representing a biological food safety hazard to consumers. The term was referred to in the United Kingdom's Specified Risk Material Order 1997 (S.I. 1997/2964), in the United States Department of Agriculture's, and in the Canadian Food Inspection Agency's regulatory response to the first confirmed U.S. BSE case in December 2003.
