Raw crabs are easy to parasitize paragonimiasis. Besides crabs, paragonimiasis and its eggs also exist in some snails and streams. People may get paragonimiasis when they eat raw or semi-cooked crabs and snails or drink raw streams, and in severe cases, they will get paragonimiasis. The guy in the news got paragonimiasis because he directly bit crabs with his mouth. Paragonimus is a chronic parasitic disease. Once suffering from this disease, it will be accompanied by chest pain, urticaria, subcutaneous nodules or lumps and other symptoms, causing varying degrees of damage to the patient's liver and other parts.
Although paragonimiasis has strong vitality, it is very afraid of high temperature. Under the action of high temperature, Paragonimus will be completely killed, but it must be cooked at high temperature for a period of time to ensure that the food has been cooked, otherwise some Paragonimus will not be killed. In order to ensure the freshness of crabs and other foods, many people choose to soak crabs and other foods with alcohol, such as drunken shrimps and drunken crabs. They think alcohol can kill bacteria and paragonimiasis. In fact, this idea is wrong. Alcohol can not completely kill the eggs or larvae of paragonimiasis, and there is still the possibility of parasitic infection after eating. The best way to kill paragonimiasis by eating seafood is to cook it by heating.
This news tells us that when eating seafood such as crabs and shrimps, we must cook them before eating them, so as to kill paragonimiasis. If you eat undercooked crabs and shrimps, paragonimiasis will enter the human body and bring different degrees of damage to people's health.
