How long can leftover food be left out of the refrigerator?

Answer: 

Hot foods should be refrigerated as soon as possible within two hours after cooking. Don't keep the food if it's been standing out for more than two hours. Don't taste test it, either. Even a small amount of contaminated food can cause illness.

Date leftovers so they can be used within a safe time. Generally, they remain safe when properly refrigerated for three to five days. If in doubt, throw it out.
