Walking on the street, you can see countless special food from different countries, especially Japanese yushi, which has numerous gourmands.Many people think that as long as the raw material is saltwater fish and the knife is clean, it is safe to eat. Is that true?Anisakiasis, a parasite from the sea, can survive in seawater, and with uncooked sashimi, enter the gastrointestinal tract of the human body, turn upside down in the stomach, “open the belly”, and this parasitic disease is easily misdiagnosed, once infected, can even lead to breathing difficulties, shock.How high is the infection rate of this parasite?In a large-scale investigation in Fujian Province, a total of 810 fish from 32 species were dissected, and 277 fish from 19 species were infected with anisakis larvae.If you think this is just a coincidence, you are totally wrong. According to the data, the infection rate of anisakiasis in shandong Rizhao Yellow Sea fish is 45.5%, the infection rate of shenzhen market fish is 31.9% and the infection rate of zhoushan port fish is higher, reaching 56.0%.Cases of the disease have been reported in more than 20 countries including Japan, the Netherlands, the United Kingdom, France, Germany and the Pacific Region, among which more than 14,000 human cases have been reported in Japan.In addition to entering the intestines and stomach, which can cause vomiting and severe pain lasting several weeks or even years, a very small number of anisakiasis can penetrate into the mucous membrane of the throat and cause esophageal anisakiasis, which is characterized by itching, nausea or cough and sputum.The larvae can also migrate to the liver, pancreas, omentum, mesentery, ovary, subcutaneous abdominal wall, groin or oral mucosa, causing peritonitis, eosinophilic granuloma and subcutaneous mass, which is often misdiagnosed as malignant tumor.Can traditional soju, soy sauce and vinegar kill anisakis nematodes?Like any parasite, the answer is no.One might ask, “Are only a few species of Marine fish hosts?”According to the survey, mackerel, autumn knife fish, salmon, sardines, octopus and other seafood can be detected with anisakis nematodes.Once diagnosed, are there medications available to treat it?Praziquantel, which can treat liver fluoriasis, does not treat anisakiasis.Other anti-parasitic drugs, such as levamisole, have no effect at all on anisakis.This dreaded parasite can only be treated completely by surgical removal.Therefore, to be on the safe side, please be careful to eat raw seafood, especially salmon from Europe and the United States, the rate of infection with anisakiasis has been increasing.Like other parasites, anisakiasis can survive at 60℃ for less than a minute, which may be a preventive medicine.Finally give a poem, I wish you to take health as the priority, do not try insects with body: wasabi liquor is useless, high temperature to kill insects for a few minutes.There is no magic bullet.
