Fridge at 40°F (4°C) or colder, freezer at 0°F (−18°C). Freezer times are for best quality; food kept frozen stays safe indefinitely.

Keep seafood in the coldest part of the fridge and use it quickly. Thaw frozen seafood in the fridge, not on the counter.
Common questions
How long do crab legs last in the fridge?
2–4 days in the refrigerator at 40°F (4°C) or below, according to USDA FoodKeeper data.
Can you freeze crab legs?
Yes. Frozen at 0°F (−18°C), crab legs keep best quality for 9–12 months. Frozen food stays safe indefinitely; the time is for taste and texture.
How can I tell if crab legs have gone bad?
Throw them out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
