sea crabs can also be

crabs, which are ugly in appearance and rampage when they walk, but they are extremely delicious, especially the hairy crabs produced in Yangcheng Lake in Jiangsu Province, which are fat and yellow in late autumn and are famous all over the world.

fresh crabs are very delicious. However, if the caught crabs die, the umami taste will be gone, and people may have poisoning symptoms after eating them. So, what is the reason?

Crabs live in water and like to eat dead fish, dead shrimps and other corrupt animal carcasses, so they will be infected with certain bacteria. Especially river crabs, most of them grow in dirty ponds, and a large number of germs are stained inside and outside the crabs. Live crabs can excrete bacteria through metabolism in the body; Once a crab dies, the bacteria in his body will multiply and decompose crab meat, and some bacteria also produce toxins. If people eat such crabs, they will cause food poisoning, and the common manifestations are nausea, vomiting, abdominal pain and diarrhea. In severe cases, dehydration, electrolyte disorder, convulsion, even shock, coma and septicemia may occur.

In case of the above situation, the patient should be sent to the hospital immediately, given glucose saline or compound sodium chloride intravenous drip, supplemented with liquid, and encouraged to drink more water and tea. Timely potassium supplementation to maintain electrolyte balance, sensitive antibiotics to control and prevent infection. Give antihypertensive drugs and other symptomatic treatment to those with low blood pressure.
