How far off the floor must food be stored on shelves?

Food must be stored off the floor to prevent contamination and ensure proper sanitation in food storage areas. A minimum elevation of 6 inches is required to allow for adequate air circulation and to minimize the risk of pests, dirt, and moisture from the floor contaminating the food. This height helps protect food items from spills and other potential hazards that can occur at ground level. Storing food in this manner is a crucial practice in maintaining food safety standards and preventing foodborne illnesses.
