Does cooked shellfish go bad?

Yes. The fridge time above is the window USDA gives for good quality; after it, cooked shellfish may still be safe for a short while but quality drops and spoilage signs start. The date on the package is the maker's quality promise; the times here count from purchase unless marked "from the package date".

Two numbers to keep in mind: a fridge at 40 F (4 C) or below, and no more than 2 hours at room temperature (1 hour above 90 F / 32 C) for anything perishable.

How to tell cooked shellfish has gone bad

  • Shells that stay open and will not close when tapped
  • Cracked or broken shells on live shellfish
  • Strong ammonia or sour smell instead of a fresh sea smell
  • Shrimp with a slimy texture or spreading black spots
  • Live shellfish that float in water instead of sinking
