What kind of crab should not eat?

Dead crab

Dead crabs can't be eaten, even if they are just dead, it is best not to eat. Crab is a omnivorous animal. It is especially fond of eating dead bodies of animals and plants, so it inevitably carries a lot of bacteria and viruses. Due to its own metabolism, live crabs can compete with microorganisms and inhibit their reproduction. After the crabs die, these microorganisms can use their rich nutrients to rapidly multiply, causing the crabs to spoil and produce a variety of toxins. People may experience symptoms of food poisoning such as fever, vomiting, abdominal pain, and diarrhea after eating.

In addition, the crab meat is rich in histidine. When the crab dies, some bacteria containing histidine decarboxylase can decarboxylate the histidine in the crab meat to form a large amount of histamine under appropriate conditions. Histamine is a sensitizing substance that can dilate small veins and capillaries, promote the secretion of mucous membranes and glands, cause allergic symptoms, and cause circulatory failure.

Crab processed by "washing crab powder"

Not long ago, some unscrupulous businessmen in the market found that they were tempted by economic interests and lost their professional ethics. They used “washing crab powder” to “clean” ordinary rice field crabs and act as high-end Yangcheng Lake hairy crabs to make huge profits. "Washing powder" is an industrial oxalic acid solution which has a strong corrosive effect and is generally used as a rust remover in the industry. Eating crabs treated with them may cause damage to the mucous membranes of the digestive tract. At the same time, oxalic acid is also an antagonist of divalent ions such as magnesium, calcium and iron. It not only hinders the body's absorption of these minerals, but also forms insoluble oxalates, which are deposited in the renal tubules, causing the urinary system to crystallize.
