Example of causative food

Sashimi and sushi such as mackerel, squid, salmon, horse mackerel, saury, sardine, bonito, etc.

Features

It is a thread-like, translucent white parasite of about 2 to 3 cm long, which is widely parasitic on marine seafood. It mainly parasitizes on the internal organs of fish, but can also parasitize muscles. Because it cannot become an adult in the human body, it is usually excreted when entering the body when eating fish, but rarely invades human stomach and intestines, causing severe abdominal pain.

Symptoms

A few hours to ten hours after eating, severe abdominal pain can occur and may be accompanied by symptoms such as nausea, vomiting, and hives. It can also cause peritonitis in the intestinal tract.

Preventive measures

・It is killed by cooking or freezing for more than 24 hours at minus 20 ° C.
・When freshness decreases, it is easy to move to muscles, so when eating seafood, select fresh ones and remove internal organs as soon as possible. In addition, take a close look at the edible part to remove the parasites.
・Don't eat raw fish offals.
