Taboos for eating crabs are:

1, don't eat dead crabs.

Parasitic bacteria in dead crabs will multiply and spread into crab meat, decompose protein and produce histamine. The longer the crab dies, the more histamine accumulated in the body, and the greater the toxicity. Even if the dead crab is cooked, the toxin is still not easy to be destroyed. After eating it, it will cause nausea and vomiting, flushed cheeks and rapid heartbeat.

2. Don't eat raw crabs or drunk crabs.

Hairy crabs grow in mud ditches at the bottom of rivers and lakes, and mostly feed on animal carcasses, so they contain various pathogenic microorganisms. In particular, the metacercaria of Paragonimus larvae in its body is highly infectious and resistant, and it cannot be killed by soaking in yellow wine or white wine alone. Eating raw crabs and drunken crabs can easily induce paragonimiasis, causing cough and hemoptysis. If the virus enters the brain, it will also cause paralysis.

3. Don't eat stomach and internal organs.

Hairy crabs can't be eaten in every part. Before eating crabs, four cleanings must be done, that is, the crab's stomach must be cleaned, that is, a triangular bone bag with dirty sand in the center of the front edge of the back shell; Second, remove the crab intestine, that is, a black line from the crab stomach to the crab navel; 3. Take out the crab heart, which is hexagonal, in the center of the crab, under the black film; Fourth, remove the crab gills, that is, two rows of soft things like eyebrows that grow on the crab's abdomen, also called "crab blinds". These four parts are dirty and have no edible value, and chewing them indiscriminately can easily cause food poisoning.

4. Don't eat with strong tea, persimmons and beer.

Strong tea, persimmon and other foods contain a lot of tannic acid, which will condense to form "stomach persimmon disease" when combined with protein, leading to abdominal pain and vomiting; Beer is cold. If you send crabs with beer, the coldness will increase and it will be easy to have diarrhea. Therefore, it is best to choose yellow rice wine or white wine isothermal wine to send crabs.
