Crab meat is delicate and delicious. It is a rare and precious aquatic product. It is also a delicacy that many citizens like. Although both crabs and fish also belong to aquatic products, it is not uncommon to eat crabs for poisoning. Why are all aquatic products and they are all cooked at high temperatures. Eating crabs is prone to poisoning? In this regard, the South Korean director of the Sanitation Bureau of the Health Department of Haidian District explained that "this is caused by eating fresh and undercooked, especially dead crabs."
Dead crabs contain a lot of toxins
Although crabs and fish live in water, crabs like to eat dead bodies of dead fish such as dead fish and dead shrimps, so they have accumulated a large amount of bacteria in the crab body. In particular, crabs are mostly grown in turbid rivers and ponds. There are a lot of pathogens inside and outside the crabs. When the crab is dying or dying, histidine in the crab will decompose to produce histamine, which is a toxic substance. With the prolongation of the death time, the accumulation of histamine will be more and more, so the gas will become larger and bigger. Even if the crab is cooked at this time, its toxins are not easily destroyed. . Therefore, if people eat such a crab, it will naturally cause food poisoning.
Unfamiliar crabs susceptible to paragonimiasis
In addition to dead crabs containing toxins, stale and undercooked crabs are killers of food poisoning. Han Zhuren said that this is because crabs grow in rivers and lakes, but also eat small creatures, aquatic plants and rotting animals. The body surface, ankles and gastrointestinal tracts of crabs are covered with bacteria, viruses and other pathogenic microorganisms.

According to expert research, the crabs were eaten after heating slightly. The infection rate of paragonimiasis was 20%. Eating crabs and crabs, the rate of infection with paragonimiasis is as high as 55%. For raw crabs, the infection rate of paragonimiasis was as high as 71%. The parasites of the lung flukes are very resistant, and they are usually killed by soaking in 55°C water for 30 minutes or in 20% saline for 48 hours. Raw crabs may also cause intestinal inflammation, edema, and congestion.
Long-running crabs are easily contaminated by bacteria
In addition, many people cannot eat because of fear that the crabs will die. They will cook the crabs once and then store them again, thinking that there will be no problem. But in fact, long-term cooked crabs are still a big killer of easy poisoning. This is because cooked crabs are also easily contaminated with bacteria, so crabs should be eaten immediately and not stored.
Stored cooked crabs must be returned
When eating crabs should pay attention to what issues? Cold crab meat, should not eat cold food at the same time, when eating crabs and crabs within 1 hour after drinking tea. Because boiled water will dilute stomach acid, tea will cause certain components of the crab to solidify, which is not conducive to digestion and absorption, and may also cause abdominal pain and diarrhea.
