2 hours after death, the total number of colonies surges! Overnight crabs What are the health hazard

In fact, there is a big health risk, because after death, the total number of colonies will increase, and if you eat these dead crabs or overnight shrimp, it may cause physical harm.

Dead crabs and overnight crabs are prone to histamine toxin, which can cause the dilatation of blood vessels in the human body, and the patient will have redness or rash, in addition to chest tightness, palpitation, diarrhea and other symptoms, and even shock or death in severe cases.

It may affect the person's physical condition, cause food poisoning, and may cause vomiting.

2 hours after the death of the scum repentance, the total number of colonies surged, overnight crabs and dead crabs exactly health hazards:

1. Parasites and bacteria breed. We know that crabs, fish and shrimp are rich in protein, and they are our favorite type of seafood on the table. Usually when we go to eat food stalls or restaurants, we often have a plate or two of shrimp or crabs.

However, after eating, some consumers take it home and eat it the next day in the spirit of not wasting it, which is actually wrong. Because crabs develop immunity to bacteria and parasites when they are alive, and become a breeding ground for parasites when they die. After a night, the bacteria have multiplied in large numbers.

Therefore, overnight crabs are not edible.

2. Accumulation of toxins. Bacteria produce toxins that are not good for the body's absorption and are not good for the body's health. Even after heating, some bacteria can still enter our stomachs.

In severe cases, it can cause food poisoning. Don't think that there is nothing left out overnight, in fact, the multiplication of bacteria is not something you can imagine. Especially for the elderly and children, pregnant women are more likely to get food poisoning when they accidentally eat such things.

Food safety is a concern for all of us. Don't put your body at risk just to not waste it.

3. The higher the temperature, the histamine content of dead crabs will increase slowly, and the highest score can reach 1400 ml. The amount of bacteria it carries is relatively high, and the toxins it produces are not easy to decompose. Severe patients may experience shock, nausea, vomiting, etc.

The most terrifying thing is that there is no way to kill these high-temperature heating. Crabs like to eat corrosive things like dead shrimp and dead fish in the water. So the crab itself carries a large number of bacteria.

Crabs that have been eaten overnight can cause enteritis. Therefore, for crabs, we should try to eat them while they are alive. Therefore, after cooking or overnight, if it is properly stored, it can be eaten again, but it cannot be cooked overnight.

There are a lot of bacteria in it, and the meat inside may also spoil, which can be harmful to the body if eaten.

Overnight crabs and Zen judgment dead crabs are equivalent to a petri dish and have become a hotbed for pathogenic bacteria and parasites, and after eating, it is easy to cause vomiting, abdominal pain, diarrhea and other symptoms.

If the crab has died with hail, it is best not to eat it, because it contains a lot of bacteria and colonies, and there are a lot of toxins.

The health hazard of overnight crabs and dead crabs is that the total number of colonies increases significantly after two hours of death.

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.

The bacteria in the dead crab decompose proteins at the same time 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 and dyspnea.

It can cause poisoning, it can cause allergies, it can also cause gastrointestinal upset, it may cause diarrhea, and it can also cause diarrhea.

It can affect the health of the body, there may be parasites, and it may also cause impaired kidney function, which may cause serious diseases.

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.

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.
