Why can't you eat the river crab when it's dead?

River crabs can't be eaten when they're dead, but many people don't quite understand why they can't be eaten when river crabs die?

Another important cause of poisoning in dead crabs is bacterial infection. Generally speaking, the living environment of wild river crabs is not as good as that of artificial and marine crabs, and once they die, bacteria inside and outside the body will multiply, decompose crab meat, and produce toxins. Comparatively speaking, the risk of bacterial infection is higher, and people are also more likely to develop bacterial infections after consumption.

The poison hidden by the Dead River crab is far from that. Crabs also contain more histidine, which is easy to decompose and can produce histamine and histamine-like substances under the action of decarboxylase. Especially when the crab dies, the histidine decomposes more rapidly, the longer the crab dies, the more histamine accumulates in the body, and when histamine accumulates to a certain amount, eating it will cause poisoning.

When buying river crabs, you can't pick the dead ones, because the dead river crabs are poisonous and can't be eaten, so can the freshly dead river crabs be eaten?

Don't think it's okay to eat just a little bit of dead crab meat. People who are allergic to histamine can cause a reaction even if they take a bite. For example, after eating a dead crab for 10 minutes and 3 hours, symptoms will appear, such as redness of the cheeks, flushing of the chest and the whole body, and conjunctival hyperemia of the eyes, as well as headache, dizziness, chest tightness, general fatigue and irritability.

After the crab dies, the lactic acid decomposed by sugar increases, the stiffness phase and the autolysis phase are shortened, and the parasitic bacteria in the crab body rapidly multiply and spread into the crab meat, causing the protein to decompose and produce histamine. The longer the crab dies, the more histamine accumulates in the body, and the more toxic it becomes. So to be on the safe side, it's best not to eat dead crabs.
