Don’t eat dead crabs!

Crabs live in water and like to eat dead fish, dead shrimps and other decaying animal carcasses in the water. Crabs will be infected with certain bacteria in their bodies. River crabs, in particular, mostly grow in polluted river ponds, and there are a lot of germs inside and outside the crabs' bodies. Live crabs can excrete bacteria through the body's metabolism; once a crab dies, the bacteria in its body will multiply and decompose the crab meat. Some bacteria will also produce toxins. If people eat such crabs, it will cause food poisoning, which is common. Symptoms include nausea, vomiting, abdominal pain, and diarrhea; in severe cases, dehydration, electrolyte imbalance, convulsions, and even shock, coma, and sepsis may occur. At the same time, the meat of dying and dead crabs contains a large amount of histamine decomposed by histamine, which is a toxic substance. As the death time prolongs, the more histamine accumulates, the greater its toxicity. This toxin is not easily destroyed even if the crab is cooked.

Therefore, when purchasing crabs, be sure to pay attention to whether they are fresh. Do not buy dead crabs, especially river crabs, and cook them thoroughly before use to kill the contaminating bacteria inside and outside the crabs. .
