Which parasite is known to be found in fish and seafood?

Anisakis is a parasite that is commonly associated with fish and seafood. It is a type of nematode (roundworm) that can infest various marine fish, particularly when they consume smaller fish or crustaceans that carry the larvae. When humans consume undercooked or raw fish containing Anisakis larvae, they can experience Anisakiasis, which can cause gastrointestinal issues.

Understanding the role of Anisakis in food safety is crucial for those managing food establishments, particularly those that serve raw or undercooked seafood, such as sushi restaurants. Proper cooking and freezing methods can significantly reduce the risk of Anisakis infection, thereby protecting consumer health.

The other options listed pertain to different sources of foodborne illness. For example, Giardia is primarily found in contaminated water and can affect various foods when washed with that water. Trichinella is a parasite typically associated with undercooked meat, especially pork, rather than seafood. Lastly, Ciguatera refers to a type of fish poisoning caused by eating fish contaminated with toxins from certain algae, rather than being a parasitic infection.
