About deli & prepared foods. Deli meats, prepared salads, leftovers and rotisserie chicken are ready to eat, which means any bacteria present can grow without further cooking to stop them. These foods depend heavily on quick refrigeration and short turnaround times to stay safe. All deli & prepared foods.
How to tell casseroles have gone bad
General signs for deli & prepared foods, the group USDA lists casseroles under.
- Sour, sulfur-like or generally off smell from ready-to-eat food

Storage habits that make the difference
Refrigerate deli and prepared foods within two hours of purchase or cooking, in shallow covered containers for faster cooling. Use most within three to four days, and reheat leftovers until steaming hot before eating. Freeze portions you will not finish in time, and label them clearly with the date.
