A crab must be cooked immediately or within 15 minutes of its death.
Crabs should ideally be alive until the moment they are cooked. Once a crab dies, bacteria and enzymes rapidly decompose its meat, releasing harmful toxins that can cause severe food poisoning. If a crab dies naturally before processing, it must be discarded immediately to ensure the safety and quality of the meal.
Why Dead Crabs Are Unsafe
Crabs carry specific bacteria in their digestive systems. When the animal dies, these bacteria multiply and spread through the flesh almost instantly. This process happens much faster in shellfish than in land animals. Consuming meat from a crab that died naturally can lead to shellfish poisoning, which heat often cannot prevent.
Crab Condition and Safety Limits
| Storage Method | Crab Condition | Safe Duration |
|---|---|---|
| Cool, Damp Air | Live and Active | Up to 24 hours |
| Ice Slurry | Dormant or Stunned | 1 to 2 hours |
| Room Temperature | Dead | Discard Immediately |
How to Identify a Healthy Crab
- Movement: Tap the shell or touch the legs. A healthy crab will react or pull its limbs toward its body.
- Smell: Fresh crabs have a mild, salty scent. A strong ammonia or "rotten" odor is a clear sign of spoilage.
- Resistance: When you pick up the crab, its claws should be held tight. Limp or hanging limbs indicate the crab is dead or dying.
Proper Handling Instructions
- Store live crabs in a well-ventilated, cool container with damp newspaper or burlap.
- Never submerge live crabs in standing fresh water, as this deprives them of oxygen and kills them.
- Check the vitality of every crab one final time before placing it into the pot or steamer.
- If a crab shows no signs of life when handled, do not cook it; throw it away to prevent illness.
