Capelin Mallotus villosus, a representative of the Osmeridae, is a common species found in the NorthAtlantic, Pacific and Arctic Ocean. Being one of the main components of the diet of various fish species, it plays animportant role in the circulation of different parasite species, including the nematodes of the Anisakidae. Capelin is alsoextensively caught and used for human food, and has become increasingly available to consumers in Poland. Thirty sixcapelin specimens, smoked fish bought at a store in Gdynia, were examined for the presence of Anisakidae. Tenspecimens of nematode (Anisakis simplex, Contracaecumsp.) were found in eight fish. The overall prevalence for thefish was 22.2%, with a mean intensity of 1.3 (range 1–3). Despite its widespread acquisition and use, capelin has beenthe subject of few parasitological analyses. Our findings indicate that it is a typical host of Anisakidae nematodes, aspecies of great zoonotic importance. While dead nematode specimens found in smoked fish do not pose a direct threatto humans as parasites per se, they can cause food allergies. It seems, therefore, that fish intended for consumptionshould be the subject of constant parasitological monitoring, linked to food quality control.
