The crab I just bought died in the morning, can I still eat it

You can eat it! It's still fresh without a day and a night! Although there are more bacteria! That's no problem either. There is no smell and it dies naturally! After cooking at high temperatures, there is no problem with SARS.

The germs are also killed! The cause of death is likely to be starvation, or the environment is not suitable for death, or the water quality problem is needed!

It is not recommended to eat. 1. Bacteria in the crab will multiply in large numbers, decompose crab meat, and some bacteria also produce toxins, which may be caused by eating dead crabs.

Food poisoning. 2. Crabs like to eat water.

Dead fish. Dead shrimp and other decaying animal carcasses can be infected with certain bacteria in the crab's body.

Live crabs can excrete bacteria from their bodies through metabolism in their bodies; Once the crab dies, the bacteria in the body will multiply, break down the crab meat, and produce toxins.

Convulsions, even shock, coma, sepsis, etc.

If the crab you bought in the morning dies in the afternoon, but the time of death is short, it has not spoiled, and it can generally be eaten.

It is important to note that crabs are eaten in moderation and try not to eat too much to avoid indigestion. Crabs have high nutritional value, which is rich in protein, vitamins, calcium, crab red, crab yellow and other nutrients.

Normally, whether the crab you buy in the morning and die in the afternoon depends on the length of time the crab has been dead. If the time is shorter, it can usually be eaten; If it is a long time, it is generally not allowed to eat.

Within half a day of death, there is no problem in cooking and eating thoroughly.

The crab I brought back the day before yesterday was saved with ice cubes from 9 p.m. the night before to 12 noon the next day, and the taste remained the same after cooking, so there was no problem eating it.

When the crab is dying or dead, the hidoxylic acid in the crab's body will break down to produce histamine. Histamine is a toxic substance, as the time of death prolongs, the accumulation of histamine in the crab's body increases, and the poisonous gas becomes larger and larger, even if the crab is cooked, this toxin is not easy to destroy. Therefore, never eat dead crabs.

Hello, I bought it back and it was alive, and I died the next day, if it wasn't for a long time, there was no peculiar smell, and I could eat it, and I could throw it away if I didn't worry.

Eating crabs is generally cooked, which is to ensure that its nutrients are intact and not lost. So if you bought it alive the first day and died the next day, I think you can eat it, because you just died in the process. Uh, the basic nutrients are not destroyed.

Dangers of eating dead crabs:

2. In fact, the poison hidden by the Dead River crab is far from this. Crabs also contain more histidine, which is easy to decompose and can produce histamine and histamine-like substances under the action of decarboxylase. Especially when the crab dies, the histidine decomposes more rapidly, the longer the crab dies, the more histamine accumulates in the body, and when histamine accumulates to a certain amount, eating it will cause poisoning.

The crabs bought died and could no longer be eaten.

Dead crabs produce large amounts of histamine in their bodies. Histamine poisoning occurs when humans eat dead crabs. Because histamine is an allergic poison, 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.

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.

It depends best on the situation ... The recommendations are as follows:

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.

5. If the crab has not died for a long time, it can still be eaten if it is refrigerated, remember, it is refrigerated and not frozen, and the sea crab is better than the river crab, because the living environment of the river crab is worse and there are more bacteria.

Nothing to do for a short time.

It's not good for a long time.

In autumn, chrysanthemum crab fat is the best time for people to taste crabs. Crab, the meat is delicate, the taste is delicious, and it is a precious aquatic product. Crabs are also very nutritious, with protein content several times higher than pork and fish, and higher content of calcium, phosphorus and vitamin A.

Autumn crab is delicious and nutritious, but it can cause health damage if eaten incorrectly.

Eating dead river crabs can be poisoned.

When a crab is dying or dead, the hidooxyacids in the crab's body break down to produce histamine. Histamine is a toxic substance. As the time of death prolongs, the crab body accumulates more and more histamine, and the poisonous gas becomes more and more powerful, and even if the crab is cooked, this toxin is not easily destroyed.

To buy fresh river crabs, you should do "five looks" when choosing crabs: one look at the color; Second, look at the individual; Three look at the navel; Fourth, look at the crab hair; Five, look at the action. The color of the crab should be green back and white belly; golden-clawed yellow hair; The individual should be large and healthy; The navel should bulge outward; Crab hairs should be on the crab legs; Be agile and active.

Only those who meet these 5 criteria are easy to buy.

The old man said: Stinky fish and rotten shrimp can be eaten! As for the dead crabs, I advise you not to eat ......I've had this experience a few times:

When I was studying, I bought a lot of crabs and couldn't finish them in one meal, but five or six died the next day and I was reluctant to throw them away! When I got up on the third day after steaming and eating, my whole face was swollen. (The doctor prescribed me allergy medicine, it seems to be assamine?) ）

If you die in your own home, it won't be long and you'll be fine.

Dead crabs cannot be eaten and will be poisoned.

Dead crabs, it also depends on how to eat it, of course, it also depends on how long the crab has been dead, if it has just died not long ago, you can eat it, it is best to use it to make spicy crabs, the taste will not be lost, and it is also delicious, but if the crab has been dead for a long time, it has been half a day, it is best not to eat it, the crab that has been dead for a long time is poisonous!

It depends on the time of death. If you just die, it's cooked, it's okay. Otherwise, it won't work. There will be toxins.

Dead crabs should not be eaten.

Crabs like to eat rotting food such as animal carcasses, and often carry germs and toxic components in the stomach and intestines, and crabs also contain more histidine; After the crab dies, the bacteria multiply in large numbers, and the histidine is quickly decomposed into histamine and histamine-like substances, and human eating dead crabs will cause disease or poisoning, so dead crabs should not be eaten.

I'm from Qingdao and grew up eating sea crabs. Dead crabs rot quickly, the problem of just dying that day is not big, put it in the refrigerator, cook it tonight and eat it, don't stay overnight, the dead crabs that have been eaten overnight are easy to be poisoned.

Histamine is toxic, and even when cooked, this toxin is not easily destroyed.

The longer the time of death, the more histamine accumulates in the crab body.

So it's best not to eat dead crabs.

It can be eaten, but it is best not to freeze the crab in the refrigerator, as the crab will become thinner as soon as it is frozen.

It's best not to eat it.

When the crab dies, the hidoxylic acid in the body breaks down to produce histamine. Histamine is a toxic substance, with the prolongation of death, the crab body accumulates more and more histamine, the poisonous gas is getting bigger and bigger, and those who eat dead crabs may have vomiting, abdominal pain, diarrhea, etc. So it's best not to eat it, I hope it can help you.

Those who are already dead cannot eat them. Poisonous. Next time, remember to eat it immediately after buying it, and if you don't have time to eat it right away, you can also put it in the refrigerator for two more days.

Crabs that just died that day are edible. But it is not as delicious as a live crab to eat.

River crabs can't, sea crabs can.
