Anisakid Nematodes and Potential Risk of Human Anisakiasis through the Consumption of Hake, spp., Sold Fresh in Spanish Supermarkets.

Nematode parasite species belonging to the complex are the most important cause of human anisakiasis through the consumption of (mainly) undercooked, previously not frozen, or conveniently treated fish. In Spain, the consumption of hake has been recognized as an important source of this parasitosis. With the aim of shedding light on the risk factors that can influence the potential risk of human anisakiasis in Spain through the consumption of fresh hake sold by nationwide supermarket chains, a total of 536 small hake specimens belonging to the species caught off the Northeast American coasts and caught in the Northeast Atlantic and Mediterranean waters was analysed.
