Question 5: What is the harm of eating dead crabs Sea crabs are dead, and they can be eaten after quick freezing. River crabs can't be eaten when they die, because they have hidooxytic acid in their bodies that will be decomposed into histamine, which will make people vomit and diarrhea, mainly because this substance is decomposed and excreted through the human liver and kidneys.

OK. Crabs are dying, but they are not yet dead are edible, although dead crabs will produce harmful components to the human body, but the crab bacteria that are just about to die have not had time to breed in large quantities, and some cadaverine, histamine and other ingredients have not had time to be produced.

Therefore, crabs that have just died or are dying are edible. But if the death time is too long, for example, in the current high temperature of more than 30 degrees, the crab dies for more than four hours, and soaks in unclean water, this situation is not edible.

1. It will be poisoned, and the lactic acid in the body will increase due to the fact that the crab is often trying to break free after it is obtained, which will lead to the rapid reproduction of bacteria in the body after the crab dies and spreads to the crab meat. Bacteria will break down amino acids in crabs, and then produce a harmful substance "histamine", causing allergic food poisoning; In addition, the substances that may be produced are "histamine-like", which can cause vomiting, abdominal pain, and diarrhea, so be careful when selecting.

2. Crabs like to eat dead fish, dead shrimp and other rotten animal carcasses in the water, and certain bacteria will accumulate in the crab's body. 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.

1. It is recommended to throw it away.

When crabs die, they begin to produce a substance called histamine, which is an allergic poison that can cause allergic food poisoning when consumed.

Moreover, after the crab dies, it will quickly breed a large number of bacteria and microorganisms, decomposing the nutrients in it into low-grade products, causing the crab to lose its original edible value.

Moreover, these bacteria and microorganisms will also metabolize substances that are harmful to human health, so it is recommended to throw away crabs directly and not eat them, except for those that have just died.

2 Varies from person to person.

Crabs will contain a lot of harmful substances after death, so the human body is prone to some toxic reactions after eating, such as dizziness and nausea, vomiting and diarrhea, unbearable abdominal pain, and physical weakness.

However, since everyone's physical condition is different, and the amount of dead crab consumed will also affect the result, what reaction will occur is also completely different from person to person.

3. Depending on the situation.

Crabs can be stored for about 1-3 days without dying, and long can be stored for about 7-10 days without dying, because the survival time of crabs is related to their own vitality and preservation methods.

Since dead crabs are easy to eat and are not conducive to human health, crabs with low vitality need to be eaten first and crabs with high vitality should be eaten later during the preservation period, so as to avoid death and waste.

41. Touch the eyes of the crab with your hand, if there is a blink, it means that it is still alive, if there is no blink, it generally means that it is dead.

2. Put the crab directly into the water, if the crab's mouth has bubbles, it means that it is still alive, but if there are no bubbles, it is likely to be dead.

3. Straighten the crab's claws, if they bend back naturally soon, it means that they are alive, but if there is no reaction, it means that they are dead. If it is naturally curved, it means that it is alive.
