Organochlorine pesticides residues in feed and muscle of farmed Nile tilapia from Brazilian fish farms

► We evaluated levels of total OCPs concentrations in farmed fish raised in Brazil. ► Increasing information will increase quality of fish products made in Brazil. ► We reported concentrations and accumulation features of OCPs from feed to fish. ► Endosulfan presented positive correlation between concentration in feed and fish muscle, but most of OCP did not presented correlation. ► Farmed tilapia from these fish farms did not represent a risk to human consumption.
