How many inches must fresh and frozen food be stacked away from the top of stacks and opening of air ducts?

Fresh and frozen food must be stacked at least 6 inches away from the top of stacks and openings of air ducts to ensure proper airflow and prevent contamination. This distance helps maintain the necessary circulation of cold air around the food items, reducing the likelihood of temperature fluctuations that can lead to spoilage or foodborne illnesses. Additionally, adhering to this requirement facilitates easier access for routine checks and maintenance of the refrigeration unit, promoting safe food storage practices. Proper stacking distances are essential for compliance with health regulations and ensuring the safety and quality of food products.
