Crab is a cherished shellfish revered for its sweet, succulent meat. However, like any seafood, proper handling is key to preserving crab’s delicate taste and texture. Understanding how long crab stays fresh can help maximize enjoyment of this crustacean delicacy.
With the right techniques, crab can retain quality and freshness for days to weeks. Read on for tips on storing, freezing, recognizing spoilage, and more.
How Long Does Raw Crab Stay Fresh?
For raw, uncooked crab, maximum freshness depends on whether it is alive, freshly caught, or packaged:
- Live crabs: 1-2 days maximum after purchasing
- Fresh caught crab: 2-3 days when kept chilled
- Store-bought fresh crab: 3-5 days until use or freezing
Once cooked raw crab meat will last around 3-5 days stored properly in the refrigerator. Precise shelf life depends on the type of crab as well. Delicate crab like blue crab may decline faster than heartier snow crab legs.
Proper Refrigeration and Storage
To optimize refrigerator storage time follow these guidelines
- Keep refrigerator at 40°F or below
- Store crab in airtight containers or bags
- Place crab on bottom shelf away from warmer door areas
- Avoid overcrowding refrigerator to allow air circulation
- Cooked crab can last 3-5 days, raw crab 2-3 days
Make sure cooked crab is refrigerated within 2 hours of preparation. Leaving crab out too long gives bacteria a chance to multiply, shortening shelf life.
Freezing Crab for Maximum Freshness
Freezing is ideal for long-term crab storage, lasting 6-9 months versus 3-5 days refrigerated. Follow these tips for freezing:
- Flash freeze raw crab first to maintain texture and moisture
- Use airtight freezer bags or containers
- Exclude air from packaging to prevent freezer burn
- Label bags with date frozen for easy tracking
- Store crab at 0°F or colder for best preservation
- Cooked crab meat can last 2-3 months frozen
Signs Crab Has Spoiled
Watch for these cues that refrigerated crab has gone bad:
- Ammonia or sour odor
- Discoloration or dark spots
- Unpleasant fishy or “off” smell
- Mushy or slimy texture
- Mold growth on meat or shell
Immediately discard crab with any above traits Do not taste questionable crab! Err on the side of caution
Thawing Frozen Crab
Always thaw frozen crab gradually in the refrigerator, not at room temperature. Other safe thawing methods include:
- Sealed bag submerged in cold water, changing water every 30 minutes
- Microwave on defrost setting if cooking immediately after
- As part of recipe cooking process like steaming or boiling
Avoid refreezing thawed crab. Cook within 1-2 days for best flavor and texture.
Cooking and Handling Tips
- Cook live crabs within 2 days of purchasing, don’t keep as pets
- Keep cooked and raw crab separated to avoid cross-contamination
- Discard crab left out more than 2 hours after cooking
- Steam, boil, or bake instead of microwaving to prevent rubbery meat
- Use cooked crab meat within 3-5 days and thawed frozen crab within 2 days
Determining Crab Freshness Before Cooking
Follow these tips to gauge raw crab quality:
- Live crabs should be active, not lethargic, and have a full shell
- Fresh, raw crab should have a sea breeze type of aroma, not fishy odor
- Meat should look moist and translucent, not dried out
- Fresh crab has a firm, springy texture when gently touched

Take these precautions when preparing and eating crab:
- Cook to an internal temperature of at least 145°F
- Discard any crab with an unpleasant smell or appearance

- Refrigerate leftovers within 2 hours and reheat fully when ready to eat
The Short Shelf Life of Cooked Crab
Cooked crab meat has a relatively short fridge shelf life of just 3-5 days. Eat or freeze leftovers within this timeframe. The delicate texture of crab quickly deteriorates. Signs that cooked crab has spoiled include:
- Slimy, mushy textures
- Dry, flaky meat pieces
- Ammonia or sour, “off” smell
- Change from reddish-pink to yellow or gray colors
- Mold growth on the shell or meat
Discard cooked crab with any above traits. Don’t taste questionable crab since illness can result.
Maximizing Freshness With Proper Freezing
Freezing cooked or raw crab can significantly extend its shelf life. Some tips:
- Flash freeze crab meat within 2 hours of cooking for best texture
- Use airtight freezer bags or containers to prevent freezer burn
- Exclude air from packaging by vacuum sealing or compressing
- Label packages with contents and date frozen
- Store frozen crab at 0°F or below
- Cooked crab meat can last 2-3 months frozen
- Raw crab meat can last 6-9 months frozen
Gradual Thawing Needed Before Eating
Always thaw frozen crab slowly in the refrigerator, not on the counter or in warm water. Other safe thawing methods:
- Place bag of frozen crab in a bowl of cold water, changing water every 30 minutes
- Thaw in the refrigerator 24-48 hours depending on amount
- Microwave defrost setting if cooking immediately after
- As part of the cooking process like steaming
Refreezing thawed crab is not recommended. It can degrade texture. Eat thawed crab within 1-2 days.
Identifying Spoiled Crab
Watch for these signs of spoiled crab:
- Slimy texture instead of firm and fleshy
- Unpleasant sour, fishy or ammonia odor
- Discoloration or dark/moldy spots
- Dry, flaky instead of moist, translucent meat
- Weak crab legs that are limp, not crisp
Promptly discard any questionable crab. Don’t taste it! Potential foodborne illness is not worth the risk.

How long do they stay good?
by Sharo Sigler (Baton Rouge, La.)
How long do crabs stay good after being boiled? Fully sealed (we use a vacuum sealer), we’ve eaten crab from the freezer up to a year after boiling it. After that, we ate it all, so we don’t know how much longer it will last for sure! ENJOY!
Can I eat cooked crab legs that were left out overnight? If you mean “left out overnight” as in not in the fridge, the answer is “No!” All seafood, including crab legs, needs to be in the fridge overnight before it can be eaten the next day.
How long can I keep crabs that were just caught in the fridge before I steam them? Fresh crabs that are still alive cannot be kept in the fridge. They must be kept alive in aerated water until cleaning and cooking. Putting them in the fridge (or freezer) before you clean them will kill them, and crab that is dead is BAD crab. Not going to cook them right away or can’t? You can clean them “live” and save them for later. I recommend vacuum sealing them and they will keep for months. However, if they have died you have to throw them out. Better safe than sorry (or worse yet, sick) .
