Signs crawfish has gone bad
- A sharp ammonia or sour smell.
- Straight tails after cooking — a sign they were dead before the pot.
- Soft, mushy meat or a slimy shell.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store crawfish
Live crawfish need cool air, not water — store them in the fridge under a damp cloth and leave the container open so they can breathe, never sealed or submerged. They turn fast once dead, so cook them quickly; for anything longer, peel the cooked tails and freeze them airtight.
