(51)Regulation (EC) No 853/2004 provides that the slaughterhouse operator is to receive, check and act upon food chain information providing details on the origin, history and management of animals intended for food production. The competent authority may allow food chain information on domestic solipeds to be sent to the slaughterhouse at the same time as the animals, rather than being sent in advance. The identification document accompanying equidae for slaughter should therefore form a part of that food chain information.
