What is a common source of infection for Anisakis simplex?

Anisakis simplex is a parasitic worm commonly associated with marine environments, particularly with the consumption of seafood. This organism is primarily found in marine fish and cephalopods, and its life cycle involves these animals as hosts.

Seafoods, especially cod and salmon, are well-documented sources of Anisakis infection for humans. When these fish are consumed raw or undercooked, the larvae can be ingested and lead to anisakiasis, which is characterized by gastrointestinal symptoms. Proper cooking and freezing methods are essential to eliminate the risk of infection from these parasites.

While contaminated water, freshwater fish, and raw vegetables can be sources of various foodborne illnesses, they are not relevant to Anisakis simplex. This parasite is specifically linked to marine food sources, making seafood the most significant concern in terms of infection risk.
