What is a common source of Anisakiasis?

Anisakiasis is an infection caused by eating raw or undercooked seafood that is infected with the larvae of parasitic worms in the Anisakis genus. This condition is most commonly associated with consuming certain types of raw fish and shellfish, which may carry the larvae. The lifecycle of the Anisakis parasite typically involves marine mammals, and when these parasites are transmitted to humans through insufficiently cooked seafood, they can penetrate the gastrointestinal tract, leading to symptoms ranging from mild to intense abdominal pain.

Raw seafood, such as sushi or sashimi, is especially known for being a common source of Anisakiasis because traditional preparation techniques often do not involve cooking, which would otherwise kill the parasites. While other food sources like raw beef, pork, or chicken can carry different harmful pathogens, they are not associated with Anisakiasis, hence making raw seafood the correct identification for this foodborne parasitic infection. The emphasis on proper cooking and food handling practices for seafood can prevent the risks associated with these parasites.
