Example of causative food

Sashimi and sushi such as mackerel, squid, salmon, horse mackerel, saury, sardines and bonito

Characteristics

It is a thread-shaped, translucent white parasite with a length of about 2-3 cm that is widely parasitic to marine seafood. It mainly parasitizes the internal surface of fish, but it can also parasitize the muscles. Because it cannot become an adult in the human body, it is usually excreted when it enters the body when eating fish, but in rare cases it invades the human stomach and intestinal walls, causing severe abdominal pain.

Symptoms

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

Preventive measures

・It is killed by cooking or freezing at minus 20 ° C for more than 24 hours.
・When freshness drops, it is easy to move to muscles, so when eating raw seafood, choose fresh ones and remove internal organs as soon as possible. In addition, look carefully at the edible parts to remove the parasites.
・Let's not eat raw fish's internal organs.
