| Abstract |
Aphanopus carbo. black scabbardfish, specimens from 3 Portuguese regions (the mainland. Madeira and the Azores) during four (mainland and Madeira) or two (Azores) seasons of the year were examined for the presence of Anisakis. All the fish examined (n=287) were infected with Anisakis L(3) larvae (prevalence = 100%). Significant geographical differences in intensity were found: the Azores showed the lowest mean intensity value (53.7) and Madeira the highest one (253.9). The intensity of infection was positively correlated with the host length in specimens of Sesimbra and Madeira. Significant seasonal differences in intensity were found in the studied regions. The very high values ill prevalence and intensity strongly suggest that the consumption of raw or undercooked black scabbard fish is a potential risk for human health. |
