What is the minimum height food must be stored off the floor in a refrigerator?

Food must be stored a minimum of six inches off the floor in a refrigerator to prevent contamination and ensure proper airflow. This practice helps to protect food from potential exposure to contaminants that may be present on the floor, such as dirt, moisture, or pests. Additionally, storing food above this height allows for better air circulation within the refrigerator, which is crucial for maintaining safe cooking and storage temperatures. Ensuring that food is kept off the ground is a key component of food safety regulations and contributes to the overall hygiene of the food storage area.
