An increasing number of reports worldwide stated a variety of currently used pesticides (CUPs) and legacy contaminants occurring in tissues of freshwater fish. Although few information is available on the effects of these pesticides at ecological level particularly at sub-lethal doses and their interactions in a continuous multiple exposure scenario, fish species became a promising bioindicator to understand the environmental fate and dynamic of pesticides in freshwater. This review highlights latest findings concerning bioaccumulation, biotransformation and effects of pesticides on fish health. Metabolomic and proteomic studies should help to understand consequences of pesticide exposure to fish. Finally, human food safety perspectives are also discussed. [Display omitted] •Multiple pesticides occurring in fish at sublethal doses.•Pesticide dynamics involve exposure at food web level.•Effect of multiple co-occurring stressors is currently unknown.•Non-bioaccumulated pesticides also exhibit deleterious effects to fish.•Several POPs occurring in fish are of primary interest for human food safety.
