Do not eat dead crabs or crabs that have not been steamed and cooked through. Live crabs should be steamed and cooked through. Live crabs can expel bacteria from their bodies through metabolism. Once the crab is dead, the bacteria in the body will multiply and decompose the crab meat, and some bacteria also produce toxins, causing food poisoning.
Crab body contains more histidine, the longer the crab is dead, the more histidine accumulated in the body, even if the dead crab is cooked, this toxin is not easy to be destroyed. In addition, the crab's body surface, gills and gastrointestinal tract in the presence of Schistosoma pneumoniae larval cysts and Vibrio parahaemolyticus, such as high temperature disinfection, Schistosoma pneumoniae into the human body can cause lung damage.

Therefore, eating crabs should ensure freshness, while steaming and cooking thoroughly to avoid food poisoning. If you eat spoiled crabs, abdominal pain, nausea, diarrhea and other symptoms, serious and even infectious shock, life-threatening.
