Abstract

For fishery products caught from fishing grounds in the Baltic Sea, four groups of viable parasites present possible health risks, Anisakis simplex (sensu stricto), Contracaecum osculatum (sensu stricto), Pseudoterranova decipiens (sensu stricto) and Diphyllobothrium spp. Since A. simplex and Pseudoterranova decipiens have been found in fishery products in International Council for the Exploration of the Sea (ICES) subdivisions 22, 23, 24, 25, 26, public health risks due to the presence of these parasites cannot be excluded in any fishery products caught from these areas. Migrating fish from areas where A. simplex, and to a lesser degree P. decipiens, occur may carry these parasites and reach the northern Baltic, therefore, public health risks due to parasites in all migrating fish (including salmon) in Baltic Sea cannot be excluded. C. osculatum occurs in fish throughout all areas of the Baltic Sea. However, at present it is not possible to assess the public health importance of viable C. osculatum larvae in fishery products. Diphyllobothrium spp. occurs in fish species in brackish waters of Baltic Sea. Hence all freshwater fish as well as migrating fish, including sea trout and whitefish, are of public health importance if consumed raw, since they may carry viable parasites. More research is needed to elucidate the importance of C. osculatum from fish as a source of human infection, including pathogenicity of this parasite and the anatomic distribution of the parasite in edible parts of the fish. In order to definitively identify species of anisakids, genetic/molecular methods should be more widely applied to material from all hosts of the Baltic Sea. Surveillance of anisakiasis and other parasitic infections in the human population in Baltic Sea countries should be improved
