Eating immature octopus can cause parasites to enter the body. Parasites mature in the body and lay eggs. Hatched larvae can enter the abdominal cavity through the intestinal wall and transfer to other parts of the human body, or from the liver to the lungs, or from the common carotid artery to the brain. Different parasites have different characteristics.

For example, Angiostrongylus cantonensis infection, parasites in the digestive tract can enter the blood circulation through the intestinal wall and reach various organs of the whole body through the liver, lungs and heart. But most larvae follow the carotid artery to the brain, where they molt and develop into the fourth stage larvae. After that, the adult develops from venous blood to pulmonary artery.

The worms in the metacercaria of Clonorchis sinensis can escape from its duodenum, go up against the biliary system and reach the intrahepatic bile duct through the common bile duct. Worms can also enter the intrahepatic bile duct through blood vessels or intestinal walls and abdominal cavity.

When you eat different undercooked foods, different kinds of parasites may appear. For example, eating raw fish can cause Angiostrongylus cantonensis, Clonorchis sinensis and anisole infection. Eating immature meat can cause infection of liver fluke, ginger leaf worm and tapeworm.

Extended data:

Eating immature meat is easy to be infected by ginger worms. Gastrointestinal symptoms and nutritional disorders may occur, such as abdominal pain, diarrhea and malnutrition. Children with severe infection may have symptoms such as emaciation, anemia, edema and developmental disorders. Avoid parasites, and it is best not to eat raw food. In addition, different chopping boards should be used to handle different foods during cooking to prevent cross-infection.

It should be reminded that parasites are different from bacterial infections. Eating unclean food can cause bacterial infection and acute symptoms such as vomiting and diarrhea. But after parasites eat it, they often have no symptoms at first. Parasites will lay eggs, hatch and grow in the human body, and the whole process is usually long. For example, adults of Clonorchis sinensis can live in human body for 20-30 years.

Because many parasitic infections are asymptomatic at first, or the symptoms are very mild and difficult to detect. When symptoms appear, the situation is generally more serious. Therefore, the best way to prevent parasites is to avoid "disease from the mouth".
