What are the symptoms of eating stinky crabs?

1.River (lake) crabs should be steamed and cooked thoroughly, and raw crabs should not be eaten.

River (lake) crabs feed on animal carcasses or humus, so the body surface, gills and gastrointestinal tract of crabs are covered with all kinds of bacteria and sludge. How can some people not get sick because they have not washed the crabs, they can't cook them thoroughly, or because they eat drunk crabs or pickled crabs raw, and eat the germs or parasites in the crabs? After steaming and cooking thoroughly before eating, there will be no such problem.

2.River (lake) crabs should be eaten alive, and dead crabs should not be eaten.

The stiffness period and autolysis period of river crabs after death are greatly shortened, and the bacteria in the crab will multiply rapidly and spread to the crab meat, causing vomiting, abdominal pain and diarrhea to eaters. The shell of the fresh live crab is blue-black, shiny, the umbilicus is full, and the belly is white. The shell of the dying crab is yellow, and the crab legs are soft, making it difficult to straighten out.

5.Eat less, not too much.

Crab meat is cold, and those with spleen and stomach deficiency should pay special attention to avoid causing abdominal pain and diarrhea.

6.Do not eat with tea.

Do not drink tea during or within 1 hour after eating crabs. Because boiling water will dilute stomach acid, tea will make some components of crab coagulate, which is not conducive to digestion and absorption, and may also cause abdominal pain and diarrhea.

When the crab is fat, the persimmon is also ripe, and you should be careful not to eat these two things at the same time. Because the tannic acid and other components in persimmon will coagulate the crab meat protein, the coagulated substances will ferment and rot if they remain in the intestine for a long time, causing vomiting, abdominal pain, diarrhea and other reactions, and may also cause stone disease.
