SummaryObjective: to assess the prevalence and the mean intensity of anisakids in seafood caught in Mediterranean sea, focusing on fish species at risk of being raw-consumed. Results: twelve studies were identified. Among them four studies considered fish species which are often consumed raw or lightly preserved or not thoroughly cooked anchovy, pilchard and Atlantic mackerel. Data synthesis: all pooled analyses were based on random-effect model.Anisakids prevalence in fish muscle was 0.64% (P < 0.0001), in viscera was 1.34% (P < 0.0001); overall was 0.95% (P < 0.0001). Mean intensity in muscle was 2.31 (P = 0.0083), in viscera was 1.55 (P = 0.0174), overall was 1.81 (P < 0.0005). Heterogeneity indexes (I 2 ) were significantly high with the exception of viscera mean intensity. Conclusions: anchovy, pilchard, Atlantic mackerel have a low prevalence and mean intensity of Anisakidae larvae both in viscera and in muscle. Mean Intensity is low as well.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
