Food safety experts advise that hot foods should be kept hot and cold foods kept cold until it is time to serve them. Hot items should be placed into the refrigerator cool, not hot, to inhibit bacteria growth, and foods should be covered after they are cooled, not before. Leftovers should always be properly reheated all the way through to kill off any bacteria that might be present.
