When storing items in a single reach-in refrigerator, what is the correct order from highest to lowest shelf?

The correct order for storing items in a single reach-in refrigerator is based on the principle of preventing cross-contamination. This principle dictates that raw meats should always be stored on the lowest shelves, while ready-to-eat foods should be placed higher up.

In the chosen answer, starting with lettuce at the top ensures that this ready-to-eat item is protected from any potential drips or contamination that might come from items stored below it. Sliced turkey, which is also ready-to-eat but has a higher potential risk due to being sliced, is placed in the middle. Finally, raw hamburger patties, which pose the highest risk of contamination due to their raw state, are stored at the bottom. This arrangement prevents any juices from raw meat from dripping onto other foods, thus minimizing the risk of foodborne illness.

The other options do not adhere to these safety guidelines. In particular, any arrangement that places raw meats above ready-to-eat foods increases the risk of cross-contamination, which is a significant concern in food safety practices.
