Seafood Parasitology, Biotoxins & Marine Into
- Zoonotic Anisakid Nematodes in Seafood:
- The two parasitic nematodes of greatest public health and safety concern in commercial seafood consumption are:
- Anisakis simplex (Herring worm): Inhabits pelagic fishes; ingestion of viable third-stage ($L_3$) larvae in raw/undercooked seafood causes acute gastric or intestinal anisakiasis.
- Pseudoterranova decipiens (Seal worm / Cod worm): Inhabits benthic and demersal marine fishes (cod, flatfish), penetrating human gastric mucosa upon ingestion.
