If a hairy crab has just died, will it react if it eats it?

Dead crabs produce large amounts of histamine. Histamine poisoning occurs when people eat dead crabs. Because histamine is an allergic poison, it can also be said to be allergic food poisoning. Don't think it's okay to just eat a little dead crab meat.

People who are allergic to histamine can have a reaction even if they take a bite. For example, after eating dead crabs for 10 minutes to 3 hours, symptoms such as cheek redness, flushing, conjunctival hyperemia, headache, dizziness, chest tightness, general fatigue, and irritability will appear.

It's a hairy crab that has just died, and it doesn't have any special reaction. There are a lot of seafood in the lake fresh and seafood markets, not only in large quantities but also after long-distance transportation, some hairy crabs will inevitably die, but they can also be eaten, don't worry too much.

If you really just died, cook and eat it right away, there is no major problem. If you die for a period of time, don't eat it, it has already bred bacteria and toxins, and if you eat it, you will vomit and diarrhea, and you will die in severe cases.

Can you eat a hairy crab that has just died? Why?

Hello: It is recommended that you do not eat hairy crabs that have just died. Because the bacteria multiply in large numbers after the death of the hairy sun-sen crab, it will produce toxins, which can easily cause food poisoning after eating.

Hairy crabs like to eat animal carcasses and rotting food, and their digestive tract may contain a large number of pathogenic bacteria and other harmful substances harmful to the human body. After the hairy crab is dying or dying, its rich nutrients will become nutrients for bacteria, such as proteins and fats, resulting in a large number of bacteria multiplying and producing toxins.

Hairy crabs will produce a large amount of histamine in their bodies after death, and histamine poisoning will occur when they eat dead hairy crabs.

Because histamine is an allergic poison, it can also be said to be allergic food poisoning. Don't think it's okay to eat just a little dead crab meat, people who are allergic to histamine can cause a reaction even if they eat one bite. For example, after eating a dead hairy crab for 10 minutes and 3 hours, symptoms will appear, such as redness of the cheeks, flushing of the chest and the whole body, and conjunctival hyperemia of the eyes, as well as headache, dizziness, chest tightness, general weakness and irritability.

Another important cause of poisoning is bacterial infection. Generally speaking, the living environment of hairy 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.

It should be noted that the dietary guidelines for Chinese residents recommend that each person consume no more than one crab per day. People with allergies, hyperuricemia or gout, pregnant women, the elderly, children, and the infirm should eat less or no crabs.

Once the crab dies, the bacteria in the body will multiply and decompose the crab meat, and some bacteria will also produce toxins, causing food poisoning. Crabs contain more histidine in their bodies, and the longer the crab dies, the more histidine accumulates in the body, and even if the dead crab is cooked, this toxin is not easily destroyed.

In addition, there are lung fluke larval cysts and Vibrio parahaemolyticus in the body surface, gills and gastrointestinal tract of crabs, which can cause lung damage after entering the human body without high temperature disinfection. If Vibrio parahaemolyticus invades the human body in large quantities, infectious poisoning will occur, and symptoms such as intestinal inflammation and bleeding will occur.

Therefore, crabs should be fresh, steamed and cooked thoroughly to avoid food poisoning. If you eat spoiled crabs, you will have abdominal pain, nausea, diarrhea and other symptoms, and even septic shock in severe cases, which is life-threatening.

Hairy crabs in Yangcheng Lake can't be eaten when they die:

First of all, the main reason why dead crabs can't be eaten is because once the hairy crabs in Yangcheng Lake die, the bacteria in the crab body will multiply rapidly, decompose the crab meat, and produce a toxin.

Of course, some people think that since there are bacteria, if they are cooked, the bacteria are dead, so they can eat it. In fact, this kind of thinking is wrong. The toxins on the dead Yangcheng Lake hairy crabs can't all be killed even after a few hours of high-temperature cooking, so you can't let yourself suffer for the sake of those one or two crabs, and the Yangcheng Lake hairy crabs you bought back should be eaten as soon as possible, and if you can't eat them all in a day, you can put them in the refrigerator for refrigeration

Hairy crabs that have just died or have already died are not edible. This is because when a crab is dying or dead, the histidoxyacids in the crab's body break down to produce histamine. Histamine is a toxic substance, with the prolongation of death time, the crab body accumulates more and more histamine, and the poisonous gas is getting bigger and bigger, even if the crab is cooked, this toxin is not easy to destroy.

Too high ammonia nitrogen must be excreted from the kidneys, so eating dead hairy crabs is very bad for the kidneys. Dead crab eaters may experience symptoms such as vomiting, abdominal pain, and diarrhea.

The reason why you can't eat dead crabs is that dead crabs will poison people, and there are two reasons for poisoning: first, histamine poisoning, dead crabs will produce a large amount of histamine in their bodies, and people will have histamine poisoning when they eat dead crabs, because histamine is an allergic poison, it can also be said to be allergic food poisoning, don't think that it doesn't matter if you only eat a little dead crab meat, people who are allergic to histamine can cause a reaction even if they eat a bite, for example, some people will have symptoms after eating dead crabs for 10 minutes and 3 hours, such as redness of cheeks, chest and whole body** Flushing and conjunctival hyperemia, as well as headache, dizziness, chest tightness, malaise and irritability.

Second, bacterial infection is also one of the important causes of poisoning, generally speaking, the living environment of wild river crabs is not as good as the living environment of artificial and marine crabs, once it dies, bacteria inside and outside the body will multiply in large numbers, decompose crab meat, and produce toxins, at this time, once people eat dead crabs, the risk of bacterial infection is higher, and bacterial infection is more likely to occur.

Crabs that have just died or are dying should never be eaten.

It is the right time to eat crabs in autumn and winter, but experts warn that crabs that have just died or are about to die should not be eaten.

Crabs are different from fish, even if the fish is dead, as long as the meat has not deteriorated, it can still be eaten under normal circumstances. But the crab is completely different, it is an omnivore that likes to eat the rotting carcasses of animals and plants, with a large number of bacteria and viruses. The metabolism of live crabs can compete with microorganisms and inhibit their reproduction; After the crab dies, the microorganisms will use its rich nutrients to multiply rapidly, causing the crab to spoil and produce a variety of toxins.

Food poisoning symptoms such as fever, vomiting, abdominal pain, and diarrhea may occur after eating.

In addition, crab meat also contains a type of histidine, which turns into histamine when the crab dies. Histamine is a sensitizing substance, which can dilate blood vessels, resulting in allergic symptoms such as **, mucosal congestion and edema, urticaria, nasal congestion, runny nose, bronchial asthma, nausea and vomiting, abdominal pain and diarrhea, and in severe cases, circulatory collapse. The crab is about to die or has just died, its inhibition ability is reduced, and this histamine and toxin will be produced, so you must not think that the crab is not dead or has just died and can still be eaten.

Many people think that drunken crabs can be sterilized and disinfected after being soaked in high levels of liquor, and it is no problem to eat them raw. However, the crabs living in streams and rocky beaches are likely to have a parasite called "cysts", and the alcohol in the liquor cannot kill the parasites, if you eat drunk crabs raw, the parasites enter the human body, and can pass through the intestines to the lungs in the abdominal cavity, and in severe cases, they can parasitize in the brain, liver and other organs, causing organ cysts.

There are also some unscrupulous traders who use "crab washing powder" to soak ordinary rice field crabs to pass off as the ** higher Yangcheng Lake hairy crabs. These "crab powder" and the previously hotly discussed "shrimp powder" are the same principle, the main ingredient is oxalic acid, oxalic acid has a strong corrosive effect, can also cause urinary system stones.

Also, some people can't eat crabs

People with high blood lipids and coronary heart disease. Crabs have high cholesterol content, and the daily cholesterol intake of the human body cannot be greater than 300 mg, while 100 grams of crab roe contains as much as 460 mg of cholesterol, which is exceeded if you eat more than two crabs;

Patients with digestive diseases such as gallstones, pancreatitis, and active hepatitis. Crabs have high protein content, which promotes the secretion of pancreatic juice after eating, and is easy to induce digestive tract diseases;

For gout patients, crabs are high-purine foods, which will aggravate the condition of gout patients; People with allergies, for people with a history of food allergies, protein allergies, and asthma, they cannot eat lake crabs;

Infants, crab roe and crab paste are the reproductive system and reproductive cells of crabs, which contain a large amount of sex hormones, and eating more may cause precocious puberty in children.

It is best not recommended to eat.

Crab is a scavenger with strong immunity, eating a lot of bacteria and viruses, but they are all suppressed by the crab's immunity, once the crab is dead, not even dead, just dying, bacteria and viruses will multiply in large numbers and breed some biotoxins. Because crabs like to eat decaying substances such as animal carcasses, their gastrointestinal tracts often carry pathogenic bacteria and toxic substances, and once they die, these germs multiply in large numbers; In addition, the crab body also contains more histidine, histidine is easy to decompose, can produce histamine and histidine-like substances under the action of decarboxylase, especially when the crab dies, histidine decomposition is more rapid, with the longer the crab dies, the more histamine accumulates in the body, and when histamine accumulates to a certain amount, it will cause poisoning. As long as you see the crab half-dead and unmotivated, it's best not to eat it.

If you eat such crabs, it will cause food poisoning, dehydration, electrolyte imbalance, convulsions, and even shock, coma, sepsis, etc., and the common manifestations are nausea, vomiting, abdominal pain, and diarrhea.

Hairy crab is a very high protein content of food, when the hairy crab is in a dying or dead state, the hairy crab will deteriorate, and eating it is not good for the human body, so it is not recommended to eat the hairy crab that has just died.

After the hairy crab is dying or dying, the rich nutrients inside, such as protein and fat, will become the nutrients of bacteria, resulting in the growth of a large number of bacteria, and at the same time decompose the protein into cadaverine and histamine, cadaverine and histamine are toxic, which can lead to poisoning, and histamine can cause allergies, numbness of the limbs, allergies, general weakness, and even asthma, dyspnea allergies.

What happens if you eat a hairy crab that just died?

Poisoned hairy crabs are carrivorous, often eat some dead animal carcasses, because the crab contains some bacteria, pathogenic bacteria and other substances in the body, when the hairy crab is dying or dead, the bacteria will quickly decompose the protein of the hairy crab, resulting in the rapid increase of cadaver and histamine. Cadaverine and histamine are toxic and allergenic, and eating them can cause poisoning or allergies.

After the death of the hairy crab with diarrhea, the bacteria in the body quickly invade the inside of the hairy crab, the hairy crab is rich in protein and fat, rich in nutrients, and the invading bacteria breed quickly, and it is easy to have diarrhea, vomiting, abdominal pain and other conditions when eaten.

I once heard the master of the Baxian Crab King say that the hairy crab can still be eaten if it is put in the refrigerator within 3 or 4 hours after it dies at room temperature, and it is best not to eat it again if it dies and is not put in the refrigerator for a day. After the hairy crab dies, it will breed a lot of bacteria and microorganisms, and the protein in the meat will also be broken down, and the taste will be very poor.
