What is the shelf life of opened ready-to-eat foods in the refrigerator?

The shelf life of opened ready-to-eat foods in the refrigerator is generally 7 days. This timeframe is based on various food safety guidelines, which indicate that after opening, foods such as deli meats, salads, and leftovers should be consumed within this week-long period to ensure both quality and safety.

Bacteria can grow on cooked foods and ready-to-eat items, even when stored in the refrigerator, albeit at a slower rate compared to warmer environments. The 7-day rule helps minimize the risk of foodborne illness, as harmful pathogens may begin to proliferate after this period.

While some foods may appear fine after a week or seem edible, relying solely on appearance or smell can be deceptive, hence the guideline to adhere to a 7-day maximum storage. Proper labeling with dates when items are opened can help manage this effectively, ensuring that food safety is maintained in food service operations and home kitchens alike.
