How should dry foods be stored to prevent contamination?

Dry foods should be stored elevated at least 6 inches off the floor to prevent contamination because this practice protects the food from potential sources of contamination that can exist on the floor. Elevating food storage helps reduce the risk of exposure to water, dirt, pests, and other contaminants that may be present on the floor. Additionally, this height allows for better airflow and sanitation around the food items, making it easier to clean the storage area and ensuring that the food remains safe and uncontaminated.

While storing food in airtight containers is a good practice for maintaining freshness and preventing pest intrusion, it does not directly address the importance of elevating food off the floor. Storing dry foods in direct contact with the floor increases the risk of contamination, and placing them near raw foods does not provide adequate food safety measures, as raw foods can carry bacteria that may transfer to dry goods.
