Some natural toxins can be formed in food as defense mechanisms of plants, through their infestation with toxin-producing mould, or through ingestion by animals of toxin-producing microorganisms. Pigeon Tinned kidney beans have already had this process applied and so can be used without further treatment. Risk assessments of natural toxins in food done by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) are used by governments and by the Codex Alimentarius Commission (the intergovernmental standards-setting body for food) to establish maximum levels in food or provide other risk management advice to control or prevent contamination. They have scales, gills, and paired fins. Learn how your comment data is processed. They are omnivorous but cannibalize if food is insufficient or of poor quality. Mould growth can occur before harvest or after harvest, during storage, on/in the food itself often under warm, damp and humid conditions.
