As long as you see the crabs half dead and have no energy, you better not eat them.
2 After being caught, crabs often increase lactic acid in the body because they want to break free. This will cause the bacteria in the body to multiply and spread to the crab meat after death.
Bacteria can decompose amino acids in crabs, robes produce a harmful substance “histamine” and cause allergic food poisoning; the other possible substance is “histamine-like” which can cause vomiting, abdominal pain and diarrhea.note.

Most river crabs grow in dirty river ponds. They like to eat dead carcasses of dead fish and dead shrimp in the water. Therefore, it is easy to infect bacteria. Generally, there are a lot of microorganisms in the crab.
When alive, river crabs can replace bacteria with metabolism through metabolism. Once dead, bacteria in the body will multiply, decomposing crab meat, and some bacteria will produce toxins.
In fact, dead river crabs are far from the poison.
Crab also contains high concentrations of histidine, which is easily broken down and can produce histamine and histamine-like substances under the action of deselenase.
In particular, after the death of crabs, histidine decomposes more quickly. The longer the death of river crabs, the more histamine accumulates in the body. When histamine accumulates to a certain amount, it will cause poisoning if eaten.
Of all the toxins, there is an important part-ammonia.
How can river crabs carry ammonia?
This needs to start with its rich protein.
River crabs contain a large amount of protein, and when it dies, the protein in the body will break down ammonia gas.
After dead crabs are eaten into the human body, excessive ammonia must be discharged through the human body, and this process causes health damage.
