Molecular Epidemiology of Anisakis spp. in Wedge Sole, Dicologlossa cuneata (Moreau, 1881), from Fishmarkets in Granada (Southern Spain), Caught in Two Adjacent NE and CE Atlantic Areas.

The presence of third stage larvae (L3) of Anisakis spp. in wedge sole, Dicologlossa cuneata (Moreau, 1881), purchased in fishmarkets in the city of Granada (Andalusia, southern Spain) was assessed. The wedge sole were caught in two FAO zones: area 27.IXa NE Atlantic (SW Spain coast) and area 34.1.11 CE Atlantic (NW Morocco coast). Only Anisakis larvae, type I, were detected in the largest fish (>20 cm) from the CE Atlantic. These were molecularly identified as A. simplex s.s. The prevalence (P) of Anisakis in this area was 12.5% and the mean intensity (MI) was 1. The presence of Hysterothylacium spp. larvae was also detected in the fish from both areas, with the prevalence being approximately double in the CE Atlantic area (12.5 vs. 5.7). A comparison between the Anisakisinfected and non-infected fish from this area showed that the former were significantly longer than the latter (p < 0.01). These results show that Anisakis parasitization of wedge sole sold in the markets of the city of Granada is of low prevalence and intensity (P = 4.5, MI = 1), especially in those from area 27.IXa (P = 0), indicating that the risk of human infection is low, particularly as this fish is traditionally prepared by deep-frying in oil in Andalusia (southern Spain).
