Final answer:
Raw foods in a refrigerator must be stored below ready-to-eat foods to prevent cross-contamination.
Step-by-step explanation:
When storing raw foods in a refrigerator, it is important to prevent cross-contamination by placing them below ready-to-eat foods. This is to ensure that any bacteria or other microbes present in the raw foods do not come into contact with foods that will be consumed without further cooking. By storing raw foods below ready-to-eat foods, you can minimize the risk of foodborne illnesses caused by cross-contamination.
