What should I pay attention to when eating raw fish?

  Case Share: Ms. Huang, who looks like a 70-year-old woman and is thin and small weighing only 70 pounds, is actually only 52 years old and lying on the hospital bed, saying repeatedly: I will never eat raw fish again! The original family is well-off Ms. Huang do not know when to start, although the amount of food is not small, but the weight is a strong reduction, people also look older. Until a short time ago, she came to the Third Hospital of Southern Medical University because of cough and pneumonia, and after a CT examination, she found a mass below the common bile duct, and initially suspected that it was a tumor in the abdomen. The apprehensive Ms. Huang was lying on the operation table.  When the doctor opened Ms. Huang’s abdominal cavity, he found that the surface of the liver was diffusely distributed with nodules the size of beans, and when he cut open Ms. Huang’s dilated common bile duct, he found a piece of worms like small tea leaves swimming inside, and after pathological examination of the worms and the small nodules in the liver, he was diagnosed with hepatic schistosomiasis.  These liver flukes, which are long-term parasites in the bile ducts of the liver, usually stick to the walls of the bile ducts with suckers and feed on the nutrients in the bile, and can survive for 20-30 years. The eggs and dead bodies of liver fluke can form the core of stones in the bile ducts, which can easily block the bile ducts and cause cholangitis.  The cysts of liver fluke are highly resistant, and soy sauce, vinegar, mustard and wine cannot kill the cysts in the fish, therefore, eating fish, shrimp and crab must be cooked at high temperature. Experts say that if you have ever eaten “raw fish” and are worried about being infected with liver fluke, you can go to the hospital to check if there are liver fluke eggs in the stool, or do an immunological intradermal test, draw blood to check for antibodies to liver fluke, and take praziquantel orally to achieve the effect of deworming.
