Will crabs be poisoned if they eat too much
Usually not. However, if you eat dead or undercooked crabs, you may be poisoned.
Because crabs like to eat dead fish, dead shrimp and other decayed animal carcasses in the water, certain bacteria will accumulate in crabs. In particular, most river crabs grow in dirty ponds, and there are a large number of bacteria inside and outside the crab. Living crabs can expel bacteria from the body through metabolism in the body, but once a crab dies, bacteria in his body will multiply in large numbers. One kind of bacteria is called Proteus, which can decarboxylate proteins in the human body to produce histamine. When histamine is accumulated to a certain amount, people will be poisoned after eating. Common manifestations include nausea, vomiting, abdominal pain Diarrhea, severe cases can occur dehydration, convulsions, and even shock.
In addition, if you eat crabs that are not cooked thoroughly, you will eat the bacteria or parasite larvae in the crab, which is easy to induce diseases. If Vibrio haemolyticus in crabs invades the human body, it will cause infectious poisoning, intestinal inflammation, edema and congestion. In particular, crabs often carry a large number of metacercaria of Paragonimus. This kind of Cysticercus has strong resistance. Generally, it will not die until it is heated at 55T for 30 minutes or soaked in 20% saline for 48 hours. Therefore, if the crab is not cooked thoroughly at high temperature, paragonimiasis will take the opportunity to enter the human body, and then induce paragonimiasis, abdominal pain, diarrhea and other symptoms. Paragonimus stimulates or destroys lung tissue, which can cause cough and hemoptysis. Once it invades the brain, patients will have symptoms such as headache, nausea, vomiting and fever. A few patients can even have symptoms such as hemiplegia, aphasia, blindness and epilepsy.
How long will eating crab poisoning happen
Although eating crabs may cause poisoning, it does not always happen. If poisoning occurs, it will occur more than ten minutes after eating. When the crab is dying or dead, the protein in the crab will decompose to produce a toxic substance called histamine. With the extension of death time, the crab will accumulate more and more histamine and the toxic gas will be larger and larger. Even if it is cooked, this toxin is not easy to be destroyed. Therefore, do not eat dead crabs.
