Why should ready-to-eat foods be stored in sealed or covered containers in the refrigerator?

• A. To keep them fresh without refrigeration.
• B. To prevent cross-contamination.
• C. To reduce energy usage.
• D. To save space.

Answer: (B)

Preventing cross-contamination is the main idea. Ready-to-eat foods won’t be cooked again before serving, so any bacteria or contaminants that land on them can cause illness. When foods are stored uncovered or loosely covered, juices from raw items can drip onto ready-to-eat foods, or bacteria can transfer from shelves, containers, or nearby foods. Sealed or covered containers act as a barrier, keeping contaminants out and protecting the safety of the food. They also help maintain quality, but the primary reason is to prevent cross-contamination.
