[Parasites] The growing popularity of sushi and other raw or undercooked fish and seafood dishes in Western countries has led to an increase in illness caused by anisakid nematodes (worms), according to a study published last year in BMJ Case Reports. Anisakiasis results from eating fish or seafood contaminated with that parasite. When the worms invade the stomach wall or intestines, the result is gastrointestinal pain, nausea and vomiting, according to the CDC. Some people develop complications, including digestive bleeding, bowel obstruction and peritonitis (an inflammation of the inner wall of the abdomen). Other people may experience an allergic reaction, including swelling, skin rash or even anaphylaxis, which can cause difficulty breathing and loss of consciousness. Anisakiasis cannot be transmitted from one person to another and is most common in Japan, where sushi is king. Japan sees, roughly, 3,000 cases annually, according to the authors of the case study. However, in recent years, other parts of the globe have begun to see a rise in anisakiasis illness, according to the CDC, though the agency estimates that only a case or two are reported in the US each year.
