Where is anisakis simplex typically found?

Anisakis simplex is a parasitic nematode commonly found in seafood, particularly in marine fish and cephalopods like squid. This parasite is part of the life cycle of various marine mammals, which serve as the definitive hosts. When marine fish consume contaminated water or prey, they can become infected with A. simplex larvae. Humans can contract an infection by consuming raw or undercooked seafood containing these larvae, resulting in anisakiasis, a serious gastrointestinal condition.

In contrast, the other options revolve around food sources that do not typically harbor this parasite. Poultry, wild game, and raw vegetables are not habitats for A. simplex, and thus, do not represent the primary risk associated with this particular parasite. Understanding the environment and hosts of anisakis is critical for food safety to avoid potential health risks from consuming infected seafood.
