Dangerous parasite showing up in sushi and raw fish

Anisakiasis, also known as herring worm disease, can be caused by eating raw or undercooked fish or squid.

"A previously healthy man was admitted with severe epigastric pain, vomiting and low-grade fever since the previous week", researchers wrote.

Doctors removed it with a Roth net, and the symptoms subsided immediately. After an exam and interview, it was discovered he recently ate sushi.

An endocopsy was performed and it showed a parasite "firmly attached" in the upper gastrointestinal tract. In such cases, it is possible to cough up the worm or remove it by hand.

That increase is notable in western countries where eating sushi and other raw or uncooked fish is becoming more popular. Sometimes, vomiting expels the worm.

"It's quite common ... roundworms in fish species are something that you can come across even in the supermarket", Holley said. "This is actually the worm moving in the mouth or throat", the agency's website reads. The best ways prevent it is to avoid eating raw or undercooked fish or squid.

He said he's found the worms while preparing meals of fish purchased in the supermarket.

Scholars on the topic suggest the illness in general is under-estimated and under-diagnosed. Endoscopy showed a parasite firmly hitched in the upper gastrointestinal tract, removal of which resolved the condition in the patient nearly immediately. Seafood should be cooked to an internal temperature of at least 145 degrees Fahrenheit and fish kept for seven days should be frozen to -4 degrees Fahrenheit. The FDA recommends the following for seafood preparation or storage to kill parasites.
