Whether frequent eating of sashimi requires deworming depends on the quality of the sashimi. If the sashimi is quarantine-qualified, then the possibility of infection with parasites is small; otherwise, it is necessary to go to the hospital to check if you are suffering from parasitic infections, and then target deworming treatment. Sashimi should be frozen in liquid nitrogen for 20 hours at -35℃ or 7 days at -20℃ to kill the parasites in sashimi. If the process is qualified, there is little possibility of parasite infection after eating sashimi; otherwise, it is necessary to go to the hospital to improve the relevant examination to confirm whether it is infected with parasites. Eating sashimi may lead to infection with intestinal tapeworms such as broad-jointed tapeworm and Japanese sea tapeworm, as well as heterotrichous nematodes, Chinese testicular trematode and toxoplasma gondii, which may need to be treated with drugs such as praziquantel and albendazole. If you feel unwell after eating sashimi, please consult a doctor as soon as possible to avoid delay.
