Pesticide residue refers to the small amounts of pesticides that remain on food or other agricultural products after they have been sprayed, applied or used according to their intended purpose. These residues can be present in varying levels and are regulated by government agencies such as the Environmental Protection Agency (EPA) to ensure safe consumption for humans and animals. Pesticide residue is a term commonly associated with food safety concerns, and measures are taken to minimize or eliminate their presence through proper application techniques, storage conditions, and expiration dates.
