How long do leftovers keep?

The answer

Leftover salmon keeps for a small number of days in the refrigerator, and the exact limit comes from your local food-safety agency. The US Food and Drug Administration advises refrigerating or freezing seafood within 2 hours of cooking, or within 1 hour if the temperature is above 90 F, and dividing leftovers into shallow containers so they cool quickly. Label containers with the date, and discard anything that smells off or looks slimy.
