Japan – Parasitic anisakis worms were the number one cause of food poisoning in 2018 for the first time, with the number of patients from the disease known as anisakiasis doubling from the previous year.
Reports of food poisoning owing to anisakis nematodes in internal organs of fish have rapidly increased in recent years, especially from eating raw skipjack tuna, according to data compiled by the health ministry and released March 13.
In 2018, 468 cases among 478 patients were reported, double the 2017 figure of 230 cases among 242 patients.
As a result, cases of anisakis poisoning exceeded food poisoning by the campylobacter bacteria in chickens, with 319 cases among 1,995 patients.
Until now, infection was caused mainly by eating raw mackerel, squid or saury. However, in 2018, infection from raw skipjack tuna increased to 100 cases among 103 patients, 10-fold the previous year’s figure.
