What type of food-borne parasite is Anisaki Simplex primarily found in?

Anisakis simplex is a type of parasitic nematode commonly associated with marine environments, making marine fish the primary host for this parasite. These parasites can be found in various species of marine fish, such as herring, cod, and flounder, which serve as intermediate hosts in their lifecycle. When humans consume raw or undercooked marine fish infected with Anisakis, there’s a risk of contracting anisakiasis, a condition that can cause gastrointestinal issues.

This is why marine fish is the correct choice, as the parasite thrives specifically in sea habitats and is not typically associated with freshwater fish, pork products, or poultry. Each of those food categories presents different types of hazards and potential parasites, but Anisakis simplex specifically links to fish found in the ocean. This connection emphasizes the importance of cooking marine fish properly and being cautious when consuming raw seafood.
