Final answer:
Ready-to-eat potato salad should be stored on the top shelf of a cooler to minimize the risk of cross-contamination. Refrigeration doesn't kill bacteria but slows their growth, emphasizing the importance of proper storage.
Step-by-step explanation:
Ready-to-eat potato salad should be stored in the cooler, and the most appropriate place for it is the top shelf. This is because ready-to-eat foods are at a higher risk of contamination and should be kept away from raw foods that might carry bacteria. By placing them on the top shelf, you minimize the risk of cross-contamination from drips or spills from raw foods that are typically stored on lower shelves.
It's important to note that placing food in a refrigerator does not kill bacteria on the food. It simply slows down the growth of bacteria. Therefore, it's crucial to maintain good food storage practices to ensure food safety.
