Live crabs can't be eaten if they freeze to death in the fresh-keeping layer, but they can freeze to death in the frozen layer. Because of the low temperature of the frozen layer, it can inhibit the crab from producing bacteria, and the toxic substances in the crab can not be secreted at low temperature. To tell the difference between life and death of a crab, you can tell it by seeing if it can move.

Can live crabs be eaten if they freeze to death in the refrigerator?

Live crabs cannot be eaten if they freeze to death in the fresh-keeping layer, but they can be eaten if they freeze to death in the frozen layer. Because the fresh-keeping layer can't inhibit bacteria or sterilize, there will be a lot of bacteria and toxic substances secreted after the crab dies here.

However, the temperature of the frozen layer is low, which can inhibit the production of bacteria in crabs, and the toxic substances in crabs can not be secreted at low temperature, so crabs frozen to death in the frozen layer can continue to be eaten.

There are many ways to tell the difference between a crab's life and death. For example, we can try to press the crab's eyes, and the eyes of a living crab will generally retract. We can also take apart the rope that binds the crab and see if it will move.
