food should be stored at least which distance from the floor

Food should be stored at least 6 inches (15 centimeters) above the floor. This distance helps prevent contamination from dirt, pests, and allergens, and allows for proper cleaning and air circulation under the stored food. It is a widely recommended food safety standard, although the FDA Food Code does not specify a precise distance, 6 inches is the common accepted practice to maintain cleanliness and reduce the risk of foodborne illnesses.
