Canvas Refrigeration Inspection Mobile App Use this handy refrigeration inspection checklist to inspect any food service establishment, right on your smart phone. Here are some of the items in the checklist: Are food items received from approved sources, in good condition, and at proper temperatures? Are refrigerators and freezers kept clean (floors, walls, ceilings, fans, and shelving)? Is food thawed properly (in a refrigerator, under running water, or as part of the cooking process)? Do employees wash their hands after using the restroom, after break time, and before starting work?
