Detection reveals a 2 hour colony surge 22 hours after the death of hairy crabs! Do dead crabs have

The colony of hairy crabs surged by 22% within two hours of death, and it was not that the dead crabs could not be eaten, but that the dead crabs could not be eaten after a certain period of time.

Now is the best time to eat hairy crabs, but we buy hairy crabs in the market, and after returning home, we often find that the quality of some crabs is not very good, and even some crabs have a stinky smell, and there will be a more unpleasant smell after steaming, it is best not to eat this kind of big crab, once eaten, it will be easy to cause certain harm to the body.

Two hours after the death of hairy crabs, colonies surged by 22%.

The season of eating hairy crabs has come again, a man in Henan Province suffered from meningitis after eating crabs overnight, so ** TV commissioned the corresponding laboratory to test, proving that the total number of colonies of hairy crabs after two hours after death increased by 22% compared with before. According to relevant data, dead crabs that have been used for more than a certain period of time are not recommended for everyone to continue to use.

Freshly dead crabs are edible.

If the crab you buy is not very long after you have just died, only about half an hour, then such a crab can be eaten normally, and the number of some colonies in its body is not very large, and eating a small amount of crab will not have a more serious impact on the body. It is not recommended for everyone to eat too much, after all, crabs themselves are cold food, and eating too much will cause discomfort in the body.

Crabs that have died more than two hours later are best not eaten.

As I said earlier, the number of colonies in the body of hairy crabs will increase rapidly two hours after death, and the number of colonies in the body can increase to 55% after 24 hours, which shows that it is best not to eat crabs that have died for more than a certain time, which can easily lead to some adverse symptoms in the body. However, the number of colonies in the body of the crab does not increase until 24 hours after death.

No. Because freshly dead crabs are the same as freshly killed crabs, there will not be too many colonies in the body, so it is not necessary not to eat them.

After the crab dies, it will cause the reproduction of many pathogenic microorganisms and parasites, and if you eat dead crabs, it will cause a high incidence of intestinal infectious diseases, and cause diarrhea and endanger health; So it's better not to eat the crab when it's dead.

I think so, because crabs spoil quickly after death.

annually.

In September and October, with the fragrance of osmanthus, hairy crabs have gradually been listed, but the shelf life of hairy crabs is not long, every time the hairy crabs bought back, especially the crabs purchased online, will always encounter dead crabs, I don't know if the hairy crabs can be eaten when they die?

Hairy crab crab.

1 Can you eat hairy crabs when they die?

Fresh hairy crabs can be eaten immediately after death.

If the live crab bought back has just died, it can be cooked and eaten immediately, because at this time, the bacteria and other microorganisms in the crab have not had time to multiply and produce harmful substances, so there will be no risk of health harm to continue to eat, but if the hairy crab dies for too long, such as more than 2 hours at room temperature, it must not be eaten, and the crab meat will produce histamine and other substances that are toxic to the human body, which cannot be decomposed at high temperatures, and may cause physical discomfort if you continue to eat.

2 Can you eat frozen crabs in the refrigerator.

Live crabs can be eaten if they are frozen to death, if they have not deteriorated.

If the dead crab is frozen in the refrigerator, the first thing to confirm is whether it is a fresh live crab before freezing to death, if it is a dead crab and then frozen, it cannot be eaten, but if the live crab is frozen to death, the temperature of the frozen layer is low, which can inhibit the reproduction of bacteria, and can keep the crab fresh for about 1-3 months.

3 What happens to a dead crab that eats it?

It can be gastrointestinal upset or life-threatening.

Once the crab dies, the bacteria inside it will multiply rapidly, and produce histamine and other harmful substances in the crab's body, if people eat dead crabs by mistake, these harmful ingredients may cause people to have food poisoning symptoms, such as: vomiting, diarrhea, headache, body temperature rise, and even bloody stool, difficulty swallowing, language disorders, dyspnea and death, etc., so once the dead crab is eaten by mistake, there are any uncomfortable symptoms, you should seek medical attention as soon as possible, so as not to miss the best opportunity.

4 How to tell how long a crab has been dead.

1. Pinch the shell: The crab shell becomes soft, indicating that it has been dead for a long time.

2. Look at the weight: If the weight of the crab is reduced, it is very empty, which means that it has been dead for a long time, especially frozen crabs.

3. Look at the legs: The crab legs are pulled down, and they are very loose, which also means that they have been dead for a long time.

4. Smell the taste: If you smell the fishy smell of the crab, it means that the crab has spoiled and can no longer be eaten.

No, dead crabs will produce a lot of histamine in their bodies, and eating dead crabs will cause histamine poisoning. Histamine is an allergic poison that can be said to be allergic food poisoning. After eating the 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.

Dead crabs can not be eaten, another important cause of poisoning of dead crabs is bacterial infection, wild river crabs living environment is not as good as artificial and marine crab living environment, once dead bacteria inside and outside the body will multiply in large quantities, decompose crab meat, and produce toxins. There is a higher risk of bacterial infections and is also more likely to develop bacterial infections after consumption.

Extended Information: Eating is a harmful effect of crabs.

Crabs mainly eat dead fish and dead shrimp that are rotten in the water, crabs breathe with gills, there are often sludge, weeds and other substances in the gill slashes, and there are many bacteria in the body, when the crab is alive, the bacteria can be excreted with the metabolism in the body, once the bacteria in the body are dead, they will multiply in large numbers and decompose the crab meat, some bacteria will produce toxins, and the dead crab people are prone to poisoning after eating.

As the crab dies for a longer time, 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. Eating such dead crabs can cause food poisoning, and the common manifestations are nausea, vomiting, abdominal pain, and diarrhea; In severe cases, dehydration, electrolyte imbalances, convulsions, and even shock, coma, sepsis, etc. may occur.

You can't eat it for as long as you want.

Because the hairy crab itself lives in a dirty river pond, there are a large number of germs in the body, and the live crab can also excrete the bacteria from the body through metabolism, but the dead crab not only cannot discharge the bacteria, but also allows the bacteria to multiply in large numbers, and the high protein quickly deteriorates, causing food poisoning. Moreover, hairy crabs are easy to rot after death, and the crab contains a substance called histidine, and when dying or dead, the histidine in the crab's body will be broken down 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.

It can be eaten within an hour, but it is best not to eat after an hour.

Hairy crab is a delicious food, which is loved by everyone in life, and many people always like to buy more and save it when they buy it, or eat the leftover overnight crab because the food is sufficient. Some people believe that dead crabs cannot be eaten because dead crabs produce a toxic substance that is not good for human health. There are rumors on the Internet that the total number of colonies of hairy crabs has surged two hours after death, so how to judge whether there is a risk of eating hairy crabs after death?

1. It is understood that the hairy crab just dies to two hours of death is 20% of the total number of colonies, and the longer the dead time, the higher the growth of the total number of colonies, and the hairy crab that dies for one day will have an obvious rancid smell. Not only that, after the death of hairy crabs, the nutrients inside will also become nutrients for bacteria, resulting in the growth of a large number of bacteria, even if they are cooked at high temperatures, they cannot destroy the microorganisms in them.

Second, after the hairy crab dies, the bacteria in the body will decompose the protein at the same time and turn into cadaver and histamine, resulting in a kind of toxicity, which will lead to poisoning after eating, and histamine will cause allergies, and after eating, there will be numbness in the limbs, allergies, general weakness, asthma, dyspnea and other allergic phenomena, it is recommended that after the hairy crab dies, try not to eat it again.

Third, to judge whether there is a risk of eating after the death of hairy crabs, mainly through two points to judge, first, to see whether the total number of colonies is increased, whether there are pathogenic bacteria, and secondly, to see whether the crab will produce harmful biogenic amines in the body after death. In fact, it is difficult to judge whether dead crabs are at risk of eating by the naked eye, so as long as the crabs are dead, they should not be used again.

In addition, it is best to eat crabs at high temperature, and some harmful bacteria in crabs can be eliminated through high-temperature cooking, which is also the healthiest way to eat.

You can directly observe the time of death of the crab, and you can also smell the smell directly, if it stinks, then you must not eat it.

After the crab dies, we will definitely have a certain risk after eating, but the probability of this risk may be relatively small, so there is nothing wrong with people eating dead crabs every day.

It is necessary to see if harmful biogenic amines are produced in the body after the crab dies.

If the hairy crab dies for more than two hours, it can not be used again, because at this time, there will be a lot of bacteria in the body, although it will not cause body poisoning, but it is likely to have adverse reactions, so you must eat fresh hairy crabs. If you want to taste the delicious hairy crab, you can choose to use the steaming method to eat it hot after cooking, so that you can not only absorb the nutrients in the hairy crab, but also feel the deliciousness of the meat. There are also some tricks to eating hairy crabs, you can choose to use scissors to cut open the crab shell, and be sure to remove the internal organs and gills of the crab.

Through testing, it was found that the colony growth of the crab in the body increased by 22% within two hours after death, and it will increase by 55% in about 24 hours. There are also some differences between hairy crabs and pike crabs, in the case of pike crabs, there will be a surge of colonies after 24 hours of death. <>

Before eating crabs, be sure to wash them carefully, and it is best to soak them in lightly salted water for a while, which can also better remove dirt. It must be cooked and eaten, the protein content in hairy crabs is very rich, and when the weather temperature is relatively high, after cooking, bacteria will also multiply in the body of hairy crabs, so it will be more appropriate to eat them immediately after cooking. There are three parts of the crab that cannot be used, so be sure to pay special attention.

There will be white soft things on both sides of the crab's abdomen, which belongs to the crab gills, when the crab lives in the water, it also needs to filter impurities through the crab gills, the crab intestines are next to the crab roe, the color is relatively black, and it must be cleaned up before eating crabs. There will be a triangular shape in the crab roe, which belongs to the crab stomach, and it should also be removed in advance so that you can eat clean and delicious crabs.

Eight crabs can be used to eat crabs, and it is very convenient to use tools to eat them, and your hands will not get dirty.

First take off its crab cover, then use a small spoon to dig out the crab roe in the middle and eat it, skim off its legs, and cut it with scissors to take it out.

When eating crabs, be sure to steam the crabs, eat crabs with some perilla, don't eat too many crabs at one time, don't eat the head of the crab.

Have you eaten crabs during the Mid-Autumn Festival this year? During the Mid-Autumn Festival, you can't eat golden crabs. There are also many flavors of crab:

There are countless methods such as steaming, stir-frying, spicy crab, salt-baked crab, etc., but if you accidentally eat some dead crabs, it is easy to bring a lot of risks to your body, so let's talk about it. <>

CCTV released a new study: the flora in the body of hairy crabs will suddenly increase by 22% within two hours after death, these hairy crabs will continue to multiply bacteria after death, and then increase by 55% in one day, and even have some rancid taste, which can no longer be eaten. The crabs that appear on everyone's Mid-Autumn Festival table are generally river crabs, river crabs are actually a freshwater product, the meat is soft, this kind of crabs basically live in small rivers or ponds with silt, their living environment leads to the high bacterial content in the crab's body, waiting for the crab to die, these bacteria and microorganisms in the body will rise rapidly, so if you accidentally eat this dead crab, it may lead to food poisoning, or the appearance of waxy bacillus in the body, Even freshly dead crabs should never be eaten.

There are also some friends who like to eat pike crabs. Barracuda crab will also appear a lot of bacteria after death, the growth environment of pike crab is relatively special, often live in the sea, the salt content in the sea water is very high, and it also has some effect on the disinfection of crabs, and the bacteria content in vitro may be less, but because the sea crab lives in the sea for a long time, it is easy to die when it is suddenly salvaged ashore, so it needs to be frozen in time, and it can not be stored for too long. Symptoms such as nausea, vomiting or gastroenteritis may occur. <>

Everyone must also pay attention when eating crabs: try not to eat raw crabs, even if they have been soaked in wine, they cannot be killed, because alcohol does not kill the parasites contained in the crab's body. When eating crabs, you must also pay attention to the removal of organs such as crab gills and crab hearts.

Eating crabs is a pleasant thing, but don't eat them dangerously.
