If there is metacercaria in liver fluke disease on shrimp, raw food will bring metacercaria into human body. Under the action of gastrointestinal digestive juice, the outer wall of metacercariae is digested, and larvae enter the hepatobiliary duct through the common bile duct and bile duct for parasitism. After about a month, the larvae can begin to ovulate and trigger liver fluke disease. The life span of clonorchiasis can reach 10 ~ 35 years. After some people eat drunken shrimp, they often have acute infection symptoms, such as high fever, chills, pain in the liver area, jaundice, and an obvious increase in eosinophilic granular cells in the blood. In severe cases, there are symptoms such as fullness in the upper abdomen and loss of appetite. Or he may die of liver failure. So shrimp should be cooked, not eaten raw.
