Something went wrong with the dead crab eating.

Uncle Xu from Hangzhou saw crabs for sale in a vegetable market a few days ago, and one of the plates contained a few dead crabs. However, the shopkeeper said that the crab had just died, ** was half of the live crab, so Uncle Xu bought four of them and prepared to drink and eat them at night.

Unexpectedly, after eating crabs, I had abdominal pain and diarrhea, and I pulled it 6 times in one night, and went to the emergency room of Hangzhou Red Society Hospital for examination, and a blood test found that there was leukocytosis, and I was diagnosed with acute gastroenteritis.

Shi Linlin, deputy chief physician of the Department of Gastroenterology, said that crabs are high-protein foods, and a large number of pathogenic bacteria will be produced two hours after death.

Crab is delicious, and it is also a necessary dish for the Mid-Autumn Festival family banquet in Hangzhou, but not everyone is suitable for eating, and patients with weak gastrointestinal function, high blood lipids, and gout should stay away. At the same time, it is best not to eat more than two crabs at a time, and be sure to choose fresh and high-quality crabs, steam them and cook them thoroughly.

What parts of crab should not be eaten?

1.Crab gills: After the crab shell is opened, the two rows of gray fan-like soft tissue on the crab body are crab gills. It is the respiratory organ of the crab, which is used to filter the water, and it is very dirty. Don't eat the triangular crab white under the gills either.

2.Crab intestines: There is crab excrement in it, after breaking the crab body, you will see that there are black things in the crab roe and crab meat, and you need to remove them.

3.Crab stomach: The triangular bun hiding in the crab roe, open the crab shell, and see that there are some crab roe on the shell, and the crab stomach is hidden in the crab roe of the shell. There is crab excrement in the crab stomach, which is very dirty and is not recommended to eat.

4.Crab heart: also called crab hexagonal plate. Open the crab shell, you can see a layer of black membrane, the crab heart is hidden under it, white hexagonal, Chinese medicine often says that the crab is extremely cold, and the crab heart is the most, must not be eaten.

In addition to dead crabs, which are not recommended to eat, the following crabs are also not recommended to eat:

1. It is not recommended to eat raw crabs and drunk crabs.

Hairy crabs feed on animal carcasses, and their bodies contain many pathogenic microorganisms, especially the lung fluke larval cysts in their bodies are highly infected and have strong resistance, and they cannot be killed by soaking in rice wine and liquor alone.

Eating raw crabs and drunk crabs can easily induce lung flukes, cause cough and hemoptysis, and cause paralysis if the virus enters the brain.

2. It is not recommended to eat stomach and internal organs.

Not every part of the hairy crab can be eaten, and these four parts must be removed before eating the crab: crab stomach, crab intestine, crab heart, and crab gills, which are both dirty and inedible.

Try not to eat itIn this case, if you have just died for an hour or two, this should not be too much of a problem, you can eat it, you can cook it directly, if it is too long, then you should not be able to eat this anymore, this is easy to spoil the stomach, and it is easy to cause gastroenteritis.

Since hairy crabs are omnivores that prefer to feed on rotting food, they carry a lot of bacteria and viruses in their bodies. Live hairy crabs are able to compete with microorganisms and inhibit reproduction due to their own metabolism.

After the hairy crab dies, these microorganisms can use the rich nutrients to multiply rapidly, causing the hairy crab to spoil in a short period of time, and may have symptoms such as fever, vomiting, abdominal pain, and diarrhea after eating.

Can you eat a freshly dead crab?

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 not the same as fish, fish just die, but the meat of the fish can be eaten without spoilage, but not crabs, crabs are omnivores, with a lot 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, there is histidine in crab meat, and after the crab dies, histidine will become histamine, and histamine is an allergenic 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 failure. 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.

Crabs can't be eaten with anything.

Crabs are very delicious, and crabs are nutritious, but there are still many people who eat crabs will have nausea and vomiting, abdominal pain and diarrhea, because they eat crabs without paying attention, crabs can not be eaten with sweet potatoes, pumpkins, honey, oranges, pears, pomegranates, tomatoes, melons, peanuts, snails, celery, persimmons, rabbit meat, nepeta; Eating crabs should not be drunk, as cold drinks can cause diarrhea.

1. You can't eat cold drinks after eating crabs.

2. You can't eat persimmons after eating crabs.

You can't eat persimmons after eating crabs. It has been recorded in "Drinking and Eating". Crabs and persimmons are both cold things, so eating the two together is easy to hurt the spleen and stomach, and people with weak constitutions should pay more attention.

In addition, persimmon contains tannic acid, crab meat is rich in protein, the two meet, will coagulate into tannic acid protein, not easy to digest and hinder the digestive function, so that the food is retained in the intestine for fermentation, vomiting, abdominal pain, diarrhea and other food poisoning.

The crab is dead for two or three hours and then it is no longer edible.

After all, crabs are living creatures, and putting crabs in the refrigerator is to properly delay the eating time of crabs, and crabs can survive for about 3 days in the refrigerator, which is already a better way to store them.

Tie the crab's legs and feet, put it in a foam box and add water. The foam box can be placed in the freezer compartment of the refrigerator to freeze. When you want to eat crabs, just take them out and thaw them, so that the preservation of crabs can ensure the freshness of crabs to the greatest extent.

Under normal circumstances, it can be stored for 5 to 7 days, but if the storage time is too long, the crab will be thinner, and eating it within 3 days will not affect the taste.

Precautions for rearing crabs in the water.

If you buy too many hairy crabs, you can directly put them in the bathtub to raise them alive, the bathtub is smooth on all sides, which can ensure that the hairy crabs will not escape from prison, put an appropriate amount of water in the bathtub (no more than 1 3cm thick) to ensure the humidity of the hairy crabs, and then put some small fish, loaches, live shrimp, etc. as their food, which can be raised for 5 10 days, and can be caught and eaten at any time.

Tips: Hairy crabs raised live at room temperature must not be brushed in advance, brushing has great damage to hairy crabs and will lead to a large number of deaths.

Crabs are not hydrophilic, can not put crabs in the water, this will cause the death of crabs, in the case of reasonable preservation, crabs put some water to maintain humidity, can survive for about 10 days, some people raise aquatic products, crabs will survive longer.

Crabs can't be eaten after a day of death.

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.

People who are allergic to histamine can cause a reaction even if they take a bite. For example, after eating a dead 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 fatigue and irritability.

In addition, another important cause of poisoning in dead crabs is bacterial infection. Once the crab dies, bacteria inside and outside the body multiply, breaking down the crab meat and producing toxins. Comparatively speaking, the risk of bacterial infection is higher, and people are also more likely to develop bacterial infections after consumption.

If there is no odor, it should be edible. When eating, clean the internal organs and wash them. Crab and other seafood are cold foods, and it is best to eat them with ginger vinaigrette, the taste will be different, and it is good for the body!

It cannot be eaten, and dead crabs contain toxins, which can easily cause food poisoning.

The reason why crabs can't be eaten when they die:

1. According to the living habits of crabs, dead crabs are not recommended to eat. Crabs love to eat rotten food, and pathogenic bacteria and toxic substances accumulate in their bodies. Dead crabs can quickly grow a large number of bacteria in their bodies, so they should not be eaten, especially in hot weather.

2. In terms of taste, the crab loses its original umami after it dies. There is also a histidine substance in the crab's body, histidine is easy to decompose, histamine and histamine-like substances can be produced under the action of decarboxylase, and the midgut gland will quickly fall apart after the crab dies, and the histidine and digestive enzymes in it will decompose the crab meat. Therefore, the taste of dead crabs is strange and the taste is greatly reduced.

3. The crab itself is non-toxic, but after the crab dies and the crab's shell is damaged, the protein in the crab's body will breed bacteria, and the infected bacteria in its body will multiply in large numbers, and the bacteria may produce toxins. Dead crabs are likely to be poisonous.

4. The body of the crab is easy to carry heavy metals, after the crab dies, the midgut gland will soon fall apart, and the digestive enzymes in it will decompose the crab meat, and the intestinal gland is relatively easy to enrich heavy metals, and the heavy metals will also come out to produce pollution after it rots.

If it's a refrigerated frozen crab, it's still edible, if it's bought back or dead, don't cherish the money and eat it, it's poisonous, the body matters!

Don't eat it!! When the crab dies, the histidoxytic acid in the crab body will decompose to produce histamine, histamine is a toxic substance, with the prolongation of death, the crab body will accumulate more and more histamine, and the poisonous gas will become larger and larger, even if the crab is cooked, this toxin is not easy to be removed...

No This kind of high-protein will give birth to a lot of parasites immediately after death! Don't eat it!!

As long as there is no odor, you can eat it!

You can eat it, and you can eat it without smelling weird!
