Sections 31A.03 and 31A.04 apply to carcasses or parts of animals, poultry, or poultry food products, and meat or meat products derived from them that are usable as human food, when these items are brought into a slaughtering, meat canning, salting, packing, rendering, or similar establishment, where inspection under sections 31A.01 to 31A.16 is done. Examination and inspection must be made before the carcasses or animal parts may enter into a department where they are to be treated and prepared for meat food products or poultry food products.

Sections 31A.03 and 31A.04 also apply to products which, after having been issued from a slaughtering, meat canning, salting, packing, rendering, or similar establishment, must be returned to it or to a similar establishment where inspection is done.

The commissioner may limit the entry of carcasses, parts of carcasses, poultry, poultry food products, meat, meat food products, and other materials into an establishment where inspection under sections 31A.01 to 31A.16 is done to conditions the commissioner prescribes to assure that allowing the entry of articles into inspected establishments is consistent with the purposes of this chapter.
