2. Why can't crabs be eaten when they die?

Dead crabs deteriorate in taste.

The crab contains histidine in the body, histidine produces histamine and histamine-like substances under the action of decarboxylase, after the crab dies, the intestinal gland will quickly fall apart, and the histidine and digestive enzymes in it will decompose the crab meat, so the meat quality of the dead crab will deteriorate, and the taste will be greatly reduced.

Dead crabs are prone to allergies.

The histidine contained in crab meat will be converted into histamine after the crab dies, histamine is a sensitizing substance, which will cause blood vessel dilation after ingestion, ** mucosal congestion and edema, urticaria, nasal congestion, runny nose, bronchial asthma and other allergic symptoms, severe respiratory and circulatory failure, and life-threatening.

Dead crabs are susceptible to food poisoning.

Crabs are omnivores, like to eat rotten animal and plant corpses, these animals and plants contain a large number of bacteria and viruses, when the crab is alive, its own metabolism can compete with microorganisms, inhibit the reproduction of bacteria, and after the crab dies, the microorganism will use its nutrients to multiply rapidly, resulting in crab spoilage, produce too many toxins, people are prone to diarrhea, abdominal pain, vomiting, fever and other poisoning symptoms after eating.

Drunken crabs. Many people think that after the crab is soaked in liquor, it can be sterilized and disinfected, so there is no problem to eat, in fact, the crab lives in a small stream, or in the river beach, and may have parasites on the body, called "cysts", and the alcohol in the liquor cannot kill this parasite, so when eating drunk crabs raw, if they are not thoroughly cleaned up, this parasite is easy to enter the human body, pass through the intestines to reach the lungs, and even reach the liver, brain and other organs in serious cases, causing organ cysts.

Crabs of unknown origin are not to be eaten.

Some traders use "crab powder" to soak ordinary river crabs, in order to pass off as the hairy crabs of Yangcheng Lake, this kind of crab powder is the same as shrimp powder, containing a large amount of oxalic acid, oxalic acid has strong corrosiveness, the human body ingests this substance, easy to cause urinary system stones.

If crabs and persimmons are eaten together, it is easy to cause symptoms such as nausea, vomiting, diarrhea, and abdominal pain.

Reason: Persimmon is a fruit with high content of tannic acid, and if eaten with crabs, it is easy to react with the protein in the crab meat to form a protein coagulation, and this product is difficult to digest in our stomach.

2. Crab and strong tea cannot be eaten together.

If you drink tea after eating crab, it is easy to cause gastrointestinal discomfort.

Reason: The crab legs and gills in the crab will inevitably carry some bacteria, and our gastric juice has a certain bactericidal ability to do this, but if you drink strong tea at the same time, the gastric juice will be diluted, and the sterilization effect will be greatly reduced. And strong tea is also a food containing tannic acid, and should not be eaten with crabs.

In general, crabs are edible when they have just died. However, it is necessary to cook it well before eating, raw crabs have a large number of parasites and bacteria, and eating them will have an impact on human health. However, crabs that have been dead for a long time cannot be eaten.

Because the bacteria in the body will spread quickly, producing a lot of toxic substances, even high-temperature processing cannot effectively kill all bacteria. It is best not to eat dead hairy crabs, especially when the weather is hot. In terms of taste, the crab loses its original umami after it dies.

Since childhood, our parents have taught us to save, not always waste, in fact, saving is the virtue of the Chinese nation, but such a virtue is not every problem can be done and experienced. Especially in terms of diet, some people want to save on leftover stir-fried or stale food, which is not good for health, for example, hairy crabs cannot be eaten after they die.

Once the crab dies, the bacteria in their body will multiply, decompose the crab meat, and some bacteria also produce toxins, if people eat such crabs, it will cause food poisoning, common manifestations are nausea, vomiting, abdominal pain, diarrhea. And in severe cases, there will be electrolyte imbalances, or convulsions, dehydration, etc., and even shock or coma, so it is better to choose fresh food when choosing food to avoid health problems.

If the above situation occurs, the patient should be immediately sent to the hospital, given dextrose normal saline or compound sodium chloride intravenous drip, supplemented with fluids, and encouraged to drink more water and tea.

Do you understand the reason why hairy crabs can't be eaten when they die, although hairy crabs will be more expensive, but if you accidentally eat dead crabs, bacteria will invade the human body and there will be poisoning reactions, so the gains outweigh the losses, so although saving is a virtue, it is also necessary to ensure health on the basis of it.

Hairy crabs are dead and can't be eaten. Another important cause of poisoning in dead crabs is bacterial infection. Generally speaking, the living environment of wild river crabs is not as good as that of artificial and marine crabs, and once they die, bacteria inside and outside the body will multiply, decompose crab meat, and produce toxins.

Comparatively speaking, the risk of bacterial infection is higher, and people are also more likely to develop bacterial infections after consumption.

Dead crabs produce large amounts of histamine in their bodies. Histamine poisoning occurs when humans eat dead crabs. Because histamine is an allergic poison, it can also be said to be allergic food poisoning.

Hairy crabs are dying or as long as they are dead, it is best not to eat, hairy crabs are easy to rot after death, the crab body contains a substance called histidine, when dying or dead, the histidine in the crab body will decompose to produce histamine. Histamine is a toxic substance, with the prolongation of death, the crab body accumulates more and more histamine, more and more toxins, this toxin is not easy to destroy, even if it is cooked, do not eat.

Crabs live in the water and like to eat dead fish, dead shrimp and other decaying animal carcasses in the water, and the crab will be infected with certain bacteria in the body. In particular, river crabs mostly grow in dirty river ponds, and there are a large number of germs inside and outside the crabs. Live crabs can excrete bacteria from their bodies through their metabolism.

Once the crab dies, the bacteria in its body will multiply and decompose the crab meat, and some bacteria will also produce toxins, if people eat such crabs, it will cause food poisoning.
