Improperly stored leftovers can harbor harmful bacteria and toxins, putting your family at risk of food poisoning.
Foods that need special care include eggs, cooked potatoes, rice, chicken, seafood, spinach, and buffet dishes.Refrigerate perishable foods within two hours (one hour in temperatures above 90°F/32°C) and reheat leftovers to 165°F/74°C.
When in doubt, throw it out—food that smells or looks fine can still contain harmful bacteria.
