The commissioner shall appoint inspectors to examine and inspect poultry food products and meat food products prepared in a slaughtering, meat canning, salting, packing, rendering, or similar establishment, where the articles are prepared solely for intrastate commerce. For examination and inspection purposes, the inspectors must be given access at all times, whether the establishment is operated or not, to every part of the establishment. The inspectors shall mark, stamp, tag, or label as “Minnesota Inspected and Passed” all products found to be unadulterated, and the inspectors shall label, mark, stamp, or tag as “Minnesota Inspected and Condemned” all products found to be adulterated. Condemned meat food products or poultry food products must be destroyed for food purposes under section 31A.04. The commissioner may remove inspectors from an establishment which fails to destroy condemned poultry food products or meat food products.
