Which foods are safe to eat after the expiration date?

When the expiration date has passed on food or dairy products when it's still on the shelves of a supermarket, it should be considered to be unsafe for eating or drinking. In some cases a food label will say. "best to eat after the food opened 10 days or less " for example, this is an item purchased before its expiration date. Once it's opened the above notice on the label should be followed.
