When entering a walk-in cooler, which of the following needs to be corrected?

In a walk-in cooler, it is crucial to follow proper food safety practices to prevent cross-contamination and ensure that food is stored at safe temperatures. Storing raw ground beef above a tray of pork is a violation of proper food storage protocols.

Raw proteins, especially ground meats, can harbor harmful bacteria such as Salmonella or E. coli. If raw ground beef leaks or drips, it can contaminate the pork below it, increasing the risk of foodborne illness. The safe practice is to store raw meats on the bottom shelves to prevent any potential dripping onto other foods, especially ready-to-eat items.

The other situations described adhere to food safety standards: macaroni salad in a sealed container helps prevent contamination from the environment; loosely covered lasagna is at least allowed to cool safely to avoid temperature abuse; and thawing the frozen turkey on the bottom shelf minimizes the risk of drips contaminating other foods. Proper organization and storage of food items are essential in any food preparation environment to maintain food safety and hygiene standards.
