1. Dead crabs are toxic and unfit to eat.
When the crab dies, it will produce a toxic substance, which is actually produced by the decomposition of the main oxygen acid in the crab, and is called histamine. Histamine is toxic, and crabs will have more and more histamine in their bodies as the time of death increases, and the toxicity will become stronger and stronger. Although crabs should be steamed when they are eaten, histamine, a toxic substance, will not be discharged in time. Therefore, when people eat dead crabs, they are easily poisoned.
Second, dead crabs contain more viruses and are not suitable for eating.
Because dead crabs contain viruses, although crabs are dead, there will be a lot of bacteria in crabs, and even some viruses will be collected, so there are a lot of toxic substances in dead crabs. If people eat dead crabs in their daily lives, they may be infected with bacteria or even viruses. I suggest you stay away as far as possible after you find the crab dead.
3. What are the hazards of eating dead crabs?
Although crabs contain many nutritional values, they are dead and are not recommended to be eaten. After all, people eating dead crabs may lead to acute intestinal inflammation such as diarrhea and vomiting. In addition, if you want to eat crabs in your life, it is recommended to eat some fresh crabs, and you need to pay attention to the diversification of diet and balanced intake of nutrition.
Fourth, the precautions when eating crabs
Crabs contain many nutrients, but people who are weak and cold are not suitable for eating crabs. In addition, pregnant women and parturients are not suitable for eating crabs. In fact, friends should not eat crab's fishy smell and crab's internal organs when eating crabs. After all, there are many heavy metals in it, and eating too much may lead to poisoning.
