Does shrimp, crayfish go bad?
Yes. The fridge time above is the window USDA gives for good quality; after it, shrimp, crayfish 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 shrimp, crayfish has gone bad
