It is important that foods be purchased from reputable vendors, meet temperature and humidity requirements, show no evidence of being refrozen (such as container or large ice crystals on the food’s surface), be received in undamaged containers, and meet specifications. Suspect cans (dented, bloated, or showing signs of leakage) and foods in unmarked containers should be discarded. All foods should be in their original containers or clearly labeled if they have been transferred to another receptacle.
