You can't pick the dead crabs when you buy them, because the dead crabs are poisonous and can't be eaten. So can the newly dead crabs be eaten?

Freshly dead crabs can't be eaten. Dead river crabs produce a lot of histamine. People will suffer from histamine poisoning if they eat dead river crabs. Because histamine is an allergic poison, it can also be said to be allergic food poisoning.

Generally, dead river crabs contain certain toxins in their bodies, which is not good for their health. Put the live river crab in the refrigerator, only in the refrigerator, not in the refrigerator, and it will definitely die at low temperature and zero degree. When you put the crab in the refrigerator, you'd better wrap a thick towel on the outside of the crab so that it can live longer.
