Parasitic Worms Are Showing Up in Sushi

A parasite, or worm that lives in contaminated raw or undercooked fish or seafood, when ingested can cause severe stomach pain, nausea, vomiting and fevers.

The Centers for Disease Control and Prevention said the worms can attach to the walls of your esophagus, stomach or intestine.

A pain and vomit inducing parasite could be living in your sushi according to a recent medical journal case study.

The study's lead author says Japan typically sees the most cases of the parasitic herring worm.

But, new estimates suggest there are several thousand cases now in Spain.

Scholars on the topic suggest the illness in general is under-estimated and under-diagnosed. The best ways prevent it is to avoid eating raw or undercooked fish or squid.

If by chance someone does encounter a parasite while eating raw fish, some can experience a tingling sensation after or while eating the undercooked fish or squid.

Anisakiasis can not be transmitted from human to human. "Also, some people experience vomiting as a symptom and this can often expel the worm from the body", the website reads.

"It's easy to treat with an antiparasitic to kill the parasite", says Chattoo. Endoscopy showed a parasite firmly hitched in the upper gastrointestinal tract, removal of which resolved the condition in the patient nearly immediately. "This is actually the worm moving in the mouth or throat".

Consumers can sometimes even remove the worms themselves, the CDC says.

Some people, though, will never give up eating their beloved sushi or other raw fish delights.
