Experts say that the infection rate of fish metacercariae in the East China Sea is high, and the species with high infection rate are: eel, yellow? ? ? ? , dragon head fish, hairtail, white fish, herring, red snapper, small yellow croaker and? ? Fish etc.
Both high temperature and high cold can kill insects.
Because the larvae of Cnaphalocrocis medinalis have poor resistance to high and low temperatures, infectious larvae can be killed at 60℃ 10 minutes or more, so cooking fish and eating it is the most effective method to control Cnaphalocrocis medinalis.
Experts also remind the public that seafood should be cooked or frozen. If frozen, marine fish should be frozen at -20℃ for 24 hours or at -4℃ for more than 5 days to ensure the killing of parasites. Captured or purchased marine fish should be treated as soon as possible to reduce the chance of larvae migrating into fish.
In addition, the condiment mustard liquid has a strong inhibitory and killing effect on the larvae of fennel insects belonging to Fennel Family of Siniperca. Diseases caused by larvae or adults of anisakis are generally called anisakis. Studies show that the intermediate hosts are mostly marine fish, and the final hosts are marine mammals, which are distributed all over the world. Humans are mainly caused by eating marine fish and marine mollusks containing live anisakis larvae. This disease has been found in many countries, and tens of thousands of human cases have been reported in Japan alone. The only symptom of human infection with heterotrophic nematodes is gastrointestinal discomfort, and the serious symptom is sudden and severe pain in the upper abdomen with nausea, vomiting and diarrhea several hours after eating. Because of the sudden onset, it is similar to surgical acute abdomen, which often leads to clinical misdiagnosis.
