How Long Does Shrimp (Raw) Last?

Fresh raw shrimp is one of the more perishable proteins in this site's seafood section, and the smell is the fastest tell — shrimp that's turned should carry a sharp ammonia edge rather than the mild, faintly briny smell of fresh shrimp, a difference that's usually obvious within a couple of seconds of opening the package. Small black spots forming at the joints or head area, a condition called melanosis, are a cosmetic enzymatic change rather than spoilage on their own, but they're often an early signal that the shrimp is getting close to the end of its window and worth using soon.

A slimy film on the shells or flesh, rather than the naturally slightly wet surface fresh shrimp has, is the clearer physical sign that it's gone. Shrimp bought already on ice at a seafood counter should stay iced at home too, packed in a bowl set over ice in the fridge rather than just placed on a shelf, which genuinely extends its 1-2 day window closer to the safe edge. Because so much fresh-looking shrimp was previously frozen and thawed for display, treating the counter purchase date as the real start of the clock, not an assumed fresh catch, is the safer read.

Shrimp bought frozen and thawed at home for cooking should generally not be refrozen raw a second time if quality matters, since a second freeze-thaw cycle compounds the texture softening a single cycle already causes — cooking it first, then freezing the cooked shrimp, is a better way to use up a thawed batch that won't be eaten right away than refreezing it raw. Farmed and wild shrimp don't differ meaningfully in how quickly they spoil once purchased; the 1-2 day fridge window and the smell-and-texture checks apply the same way to either.
