A contaminant in food and feed is defined as any substance not intentionally added to food or feed for food-producing animals, which is present in such food or feed as a result of the production (including operations carried out in crop husbandry, animal husbandry and veterinary medicine), manufacture, processing, preparation, treatment, packing, packaging, transport or storage, or as a result of environmental contamination. Note: The term includes toxins, such as moulds, but does not include insect fragments, rodent hairs and other extraneous matter (FAO and WHO, 2019).
