Can you eat crabs when they die in winter, and can you eat crabs that have just died

1. Crabs live in shallow water, feed on microorganisms and animal carcasses in the water, when the crab is alive, the germs in the body will be eliminated from the body through its immune system and digestive organs, but when the crab dies, these germs will multiply in large quantities and even penetrate into the meat. At this time, eating dead crabs will easily cause diarrhea, vomiting, nausea and other uncomfortable symptoms.

2. Crabs have super immunity, and there are a lot of bacteria and viruses in the food that crabs usually eat, but they are suppressed by the super immunity of crabs, after the crab dies, or even when it is on the verge of death, the bacteria and viruses in the crab will begin to multiply in large quantities, and breed some biotoxins, which are easy to get food poisoning after eating. Therefore, when the crab dies, it cannot be eaten, not even for a short time.

In particular, river crabs mostly grow in dirty river ponds, and there are a large number of germs inside and outside the crabs.

Live crabs can excrete bacteria through metabolism in the body, but once the crab dies, the bacteria in his body will multiply, one of which is called Proteus, which can decarboxylize proteins in the human body, thereby producing histamine, and when histamine accumulates to a certain amount, people will be poisoned when they eat it, common manifestations are nausea, vomiting, abdominal pain, diarrhea, and in severe cases, dehydration, convulsions, and even shock. Fresh crabs should also be cooked at high temperatures, which will effectively prevent the spread of bacteria and better kill bacteria.

2. Histamine is a toxic substance. As the time of death prolongs, the crab body accumulates more and more histamine, and the poisonous gas becomes larger and larger.

3. The structure and properties of this toxin substance are stable, and it is not easy to be destroyed even at high temperatures.

4. The consumption of this kind of crab containing histamine in the body is easy to cause inflammation and allergic diseases, and can cause bronchoconstriction and mucus secretion in patients who are already sick.
