What type of food is particularly at risk for containing anisakis simplex?

Anisakis simplex is a parasite that poses a particular risk in raw or undercooked seafood. This nematode can be found in marine fish and squid, and humans can become infected by consuming raw or inadequately cooked seafood that contains the larvae. These larvae can cause a condition known as anisakiasis, which can lead to gastrointestinal symptoms and other complications.

While processed grains, freshwater fish, and cooked meats are less commonly associated with this parasite, raw seafood, specifically types like sushi or sashimi that feature fish or squid, pose the highest risk. This understanding emphasizes the importance of proper cooking techniques and food safety practices when handling seafood to prevent parasitic infections.
