The petition requests that FSIS issue regulations to require that any horse offered for slaughter for human food be identified as "U.S. Condemned" unless the slaughter establishment receiving or buying the horse obtains: 1) an accurate record of all of the horse's prior owners; 2) a record of all drugs, treatments, and substances administered to the horse since birth; and 3) verification that the horse has at no time been exposed to any substances prohibited for use in animals intended for human food . The petition also requests that FSIS issue regulations to require that any horse or horsemeat that meets the criteria describe above be tested for the presence of all potentially dangerous substances in a manner that ensures detection of any residue or any potentially dangerous substance. The petition states that if any potentially dangerous substance is found, or if testing is not available to determine the presence of any prohibited substances, the regulations must require that the horse or horsemeat be identified as "U.S. Condemned."
