Which of the following is a safe way to store food in a refrigerator?

Storing food in airtight containers at the back of the fridge is considered a safe practice because it provides the best environment for maintaining food quality and safety. The back of the refrigerator typically has a more consistent and lower temperature compared to other areas, particularly the door, where temperatures can fluctuate significantly each time it is opened. Airtight containers help prevent cross-contamination, protect food from absorbing odors, and reduce the risk of moisture loss or spoilage.

Using areas of the refrigerator that are either warmer, like the top shelf, or more prone to temperature changes, such as the door, may allow for bacteria growth and spoilage. Loosely covering or leaving food uncovered can also expose it to contaminants and odors, which compromises food safety. Therefore, utilizing airtight containers in the colder, more stable part of the fridge is the best approach for safe food storage.
