    If you want to know whether crabs are at risk of eating after death, you need to look at two points. The first is to see if the total number of colonies has increased and whether there are pathogenic bacteria. The second is to see if the crab has produced some harmful substances after it dies.

    However, after testing, it will be found that the total number of colonies of hairy crabs will increase by 22% about two hours after death. And within 24 hours it will increase by 55%, and if the hairy crab has been dead for a day, then there will be a very obvious rancid smell. <>

    Moreover, the total number of colonies will only surge 24 hours after death, so dead crabs cannot be eaten. It is because after the body crab dies, the microorganisms in its body will multiply very quickly, so the number of colonies will exceed the standard. For some crabs with excessive colonies, there is no way to completely eliminate them with home cooking, especially some heat-resistant bacteria.

    But in normal times, if it is difficult to determine the death time of hairy crabs, then you know that dead crabs can no longer be eaten. <>

    For some sea crabs, if they are dead for more than a day and smell some rancid smell, they are also inedible. It can be used for some crabs treated with ice hearts, because the bacteria have not yet multiplied, and they have already been chilled. But for crabs, it is still recommended to buy, cook, and eat freshly, and do not store them.

    Don't thaw it repeatedly, otherwise it will increase the likelihood of infection. And it is best to fry or sauté when making it, so that the temperature will be higher. <>

    Hairy crabs are very delicious for many people, and their value is relatively high, but it will be different if the hairy crab dies. Because hairy crabs are very rich in protein, if they are already dead, then they will spoil. After the hairy crab dies, a large number of bacteria will breed, and the fat and protein in the hairy crab will become nutrients.

    It also breaks down proteins, which turn into histamine and cadaverine. This is all poisonous, so it can cause poisoning after eating.

    1. The crab is dead and cannot be eaten.

    Crabs are scavenging wild animals that accumulate a lot of bacteria and parasites in their bodies. After the crab is dying and dying, the lactic acid in the crab's body will increase, causing the bacteria to accelerate their reproduction and spread, and the bacteria will decompose the amino acids in the crab's body in the process of diffusion, resulting in the production of "histamine", a harmful substance, which is not easy to be destroyed even at high temperatures, which has an impact on human health.

    2. After the crab dies, because it will release harmful substances, which is not good for the human body, so after eating, the human body may have allergic reactions such as nausea, vomiting, abdominal pain and diarrhea.

    If you eat too many dead crabs, it can also lead to food poisoning, that is, symptoms such as asthma, weakness in limbs, fainting, and dizziness.

    3 Live crabs generally blink their eyes, so when you look at them, you can touch the eyes of the crab with your hands, and the eyes of live crabs will be more flexible.

    If you want to judge whether the crab is alive, you can try to straighten the crab's legs, and if it quickly springs back to the curved state, it means that the crab is alive.

    Live crabs move when placed in water. Untie the strap of the crab, put it in clean water, and observe for about ten minutes, if the crab is moving, it means that the crab is alive, and if it is not moving, it is dead.

    41. Tie the crab with a strap to reduce the physical strength of the crab to a certain extent, and the crab will be stored for a longer time.

    2. Put the crab into the freezer layer of the refrigerator, which can preserve the freshness of the crab to a certain extent and avoid dying too quickly.

    1. Dead crabs cannot be eaten.

    Live crabs can excrete bacteria from the body through metabolism in the body, but once the crab dies, the bacteria in his body will multiply in large numbers, among which there is a bacterium called Proteus, which can decarboxylize proteins in the human body, thereby producing histamine, spine and when histamine accumulates cherry pie ears to a certain amount, people eat it will cause poisoning, common manifestations are nausea, vomiting, abdominal pain, diarrhea, severe cases can occur dehydration, convulsions, and even shock.

    2. The crab contains histidine, histidine produces histamine and histamine-like substances under the action of decarboxylase, after the crab dies, the intestinal gland will quickly fall apart, and the histidine and digestive enzymes in it will decompose the crab meat, so the meat quality of the dead crab will deteriorate, and the taste will be greatly reduced.

    The histidine contained in crab meat will be converted into histamine after the crab dies, histamine is an allergenic substance, which will cause blood vessels to dilate after ingestion, **mucosal congestion and edema, urticaria, nasal congestion, runny nose, bronchial asthma and other allergic symptoms, severe respiratory and circulatory failure, and life-threatening.

    Crabs are omnivores, like to eat rotten animal and plant corpses, these animals and plants contain a large number of bacteria and viruses, when the crab is alive, its own metabolism can compete with microorganisms, inhibit the reproduction of bacteria, and after the crab dies, the microorganism will use its nutrients to multiply rapidly, resulting in crab spoilage, produce too many toxins, people are prone to diarrhea, abdominal pain, vomiting, fever and other poisoning symptoms after eating.

    3. After buying the crab, first wash the dirt attached to its body, and then put it in light salt water for 1-2 hours to let it spit out the dirt in the stomach. Change the water twice during this period.

    Since crab meat contains more histidine, histidine can be broken down into histamine, which is a toxic substance. And the longer the crab dies, the more histamine will be in the crab's body.

    Crabs often carry lung flukes and Vibrio parahaemolyticus, which can cause paraflukes or bacterial food poisoning if left unsterilized or killed, and can be life-threatening in severe cases. The saying that "crabs are eaten raw and shrimp are eaten alive" is unscientific.

    Crabs like to eat rotten food, its stomach, intestines, gills and other parts often contain a large number of bacteria and toxic substances, so when eating crabs, do not touch these things in the mouth, let alone chew and bite, should remove these parts before eating.
