Which of the following practices is NOT a part of proper food storage?

Blocking airflow in the refrigerator is not a part of proper food storage practices. Adequate airflow is crucial in a refrigerator to maintain consistent temperatures and to ensure food is kept at safe levels. Proper airflow aids in temperature control, preventing hot spots and promoting even cooling throughout the unit. When airflow is obstructed, it can lead to temperature variation, which increases the risk of bacterial growth and spoilage of food items.

In contrast, storing food items off the floor, using airtight containers, and labeling food with dates are all essential practices that contribute to food safety and quality. Storing food off the floor helps prevent contamination from pests and dirt. Utilizing airtight containers helps protect food from moisture, air, and pests, while labeling with dates ensures that food is rotated properly and consumed within safe timeframes.
