Food production is a complex process, with the ultimate objective of the food industry and food safety regulators being to ensure that food reaching the consumer is safe and wholesome. Food generally expected to be safe may become unsafe due to the introduction of hazards during production, processing, storage, transport, or final preparation for consumption. For food derived from animals, the hazard may originate from a number of these and other sources including the consumption by food production animals of contaminated feed. Examples of hazards in food that can be linked to feed and have long been recognised include salmonellosis, mycotoxicosis, and the ingestion of unacceptable residue levels of veterinary drugs and agricultural and industrial chemicals. In addition, if the postulated link between BSE and the new variant of Creutzfeldt-Jakob Disease (nv -CJD) is established, it would be another example of food contamination originating in feed.
