How should food in the walk-in be stored to avoid cross contamination?

To avoid cross-contamination in a walk-in refrigerator, food should be stored using the "first in, first out" principle and separated by type. Raw meats should be placed on the bottom shelves to prevent drips onto other foods, while ready-to-eat items should be stored above them. Additionally, different food types should be kept in clearly labeled, airtight containers to minimize the risk of contamination. Regularly inspecting and organizing the walk-in can also help maintain safety standards.
