Keep leftovers in the fridge no more than three to four days to prevent food poisoning. If you won't eat leftovers in that time, freeze them immediately. Perishable foods, such as meat, poultry, fish, dairy, eggs and casseroles, shouldn't be left out longer than two hours, or one hour in temperatures above 90 F (32 C).
