Based on the living habits of crabs, dead crabs are not recommended to eat. Crabs love to eat rotten food and accumulate pathogenic bacteria and toxic substances in their bodies. Dead crabs will quickly harbor a large number of bacteria in their bodies, so they should not be eaten, especially when the weather is hot.

From the taste consideration, crabs lose their original fresh flavor when they are dead. There is a histidine in the body of the crab, histidine is easy to decompose, can be produced under the action of decarboxylase enzyme histamine and histidylamine-like substances, after the death of the crab in the intestinal glands will soon fall apart, which histidine, digestive enzymes will be scattered out of the decomposition of the crab meat. Therefore, the dead crabs taste strange, taste greatly reduced.
