sashimi is a taste on the tip of the tongue, a lot of people like to eat. But do you know? If the treatment is not clean, parasites can easily enter the body. No mustard, vinegar or liquor can kill the parasite. In the face of the nematode, these condiments and alcohol are totally useless. Yesterday, the Ji'nan City Center for Disease Control and prevention warned that raw fish eating marine fish will be infected with parasites.
nematode, a parasite of the nematode, is white and slightly dark at one end, and belongs to the ascariasis apex family. In more than 20 countries, such as Japan, Holland, Britain, France, Germany and the Pacific region, there are reports of the cases of this disease. Only more than 30 thousand cases of nematode disease have been found in Japan. The main reason is that the residents in these countries like to eat salted sea fish, or like the raw sea fish slices, fish liver, fish, or squid wine.
"in the market fish of our country, the infection rate of the larvae of nematode in the fish, such as yellow fish, Huanggu fish, faucet and fish, is very high. In addition, in recent years, the widely accepted salmon in China can also be infected by the nematode." Li Na, the technician of the bacterial disease Inspection Institute of Ji'nan CDC, told reporters that in recent years, sashimi is often seen on the table, and many people eat sashimi for fashion, and the risk of parasites, especially apex nematodes, is very dangerous.
according to her, according to her introduction, the human infection of this insect, the light is only gastrointestinal discomfort, the heavy abdominal sudden severe pain with nausea, vomiting, diarrhea and other symptoms after eating, fibrous gastroscopy can be seen in the gastric mucosa edema, bleeding, erosion, ulcers, the late patients can see the gastrointestinal wall tumor samples, serious sense of the stomach The dyed can cause gastric perforation. In addition to the gastrointestinal tract, worms can also form tumors in the abdominal cavity, urinary system and subcutaneous tissue. People who like to eat sashimi say that parasites can be killed by dip in mustard, vinegar, soy sauce, salt or liquor. There is no scientific basis for this. " Li Na said that gastric acid does not work too much for the nematode, but the parasite is very poor in resistance to high temperature and low temperature, and it can be completely eliminated in a pot for 15 to 20 minutes. The larvae of C. elegans are more resistant to low temperature, and the larvae of the nematode will be killed if they are frozen for more than 24 hours at 20 degrees below zero. Therefore, high temperature and low temperature are the most effective ways to eliminate the nematode.
when cleaning the sea fish, Li Na reminds us that we must focus on cleaning the fish belly. It is usually sticky in the belly of the fish and must be cleaned before cooking. There is no specific treatment for gastrointestinal nematode disease. It can be examined by fiberoptic gastroscopy and taken out of the worm.
