Which ingredient must be kept on top while storing food items?

The correct answer focuses on food safety principles, particularly concerning the prevention of cross-contamination. In food storage practices, it is critical to minimize the risk of raw meat juices dripping onto other foods. Raw meat should be stored on the bottom shelf of a refrigerator or storage area to ensure that any potential drips do not contaminate other ingredients that are ready to be consumed or are more susceptible to bacterial growth, such as cooked vegetables or dairy products.

By keeping raw meat on the bottom, you protect the integrity of other items stored above it, ensuring they remain safe and uncontaminated. This placement is an essential practice in food handling and storage protocols, aligning with health regulations and safety standards to maintain a hygienic kitchen environment.
