Which of the following is prohibited for food storage in refrigeration units?

Overcrowding refrigeration units is prohibited because it significantly hampers air circulation, which is essential for maintaining consistent and safe temperatures throughout the unit. Proper air circulation helps ensure that all food items are cooled effectively, preventing the growth of harmful bacteria that can occur when food is not kept at the appropriate temperature. By overcrowding, certain areas of the refrigeration unit may become warmer, increasing the risk of spoilage and foodborne illness.

In contrast, storing foods in covered containers, allowing air to circulate around foods, and keeping raw meats below prepared foods are all recommended practices that help maintain food safety and quality. These methods promote effective cooling, reduce cross-contamination risks, and maintain hygiene within the refrigeration environment.
