The blue crab has a short death time in the refrigerator, so it can be eaten and will not go bad.

1, the temperature in the refrigerator is low, the bacteria propagate slowly, and the blue crabs are not easy to deteriorate, so the blue crabs that just died in the refrigerator can still be eaten.

2. If the blue crab goes bad, it will have an unpleasant smell or a very unpleasant smell. If the dead blue crab in the refrigerator can't judge the time of death, you can judge whether it has gone bad and can't be eaten by the taste of the blue crab.
