How should food be stored in a refrigerator to prevent cross-contamination?

Storing raw meats on the bottom shelf, separate from other foods, is the best practice to prevent cross-contamination in a refrigerator. This method helps minimize the risk of juices from raw meats dripping onto other foods, which could lead to the transfer of harmful pathogens. By keeping raw meats on the bottom shelf, food safety is maintained because it reduces the likelihood of contamination of ready-to-eat items, such as fruits, vegetables, or cooked foods that are placed on higher shelves.

In contrast, storing all food on the same shelf can create an environment where cross-contamination may easily occur, as juices from raw foods could contact other items. Mixing packaged foods can also lead to cross-contamination, especially if the packages are not leak-proof. Similarly, placing cooked foods on the bottom shelf is not advisable, as they should be stored above raw foods to avoid any potential drip contamination. Proper organization in the refrigerator is crucial for maintaining food safety and preventing foodborne illnesses.
