Four different fresh fish species (Oroechromis niloticus, Synodontis annectens, Bagrus bajad and Mormyrus rume) from River Jega, Kebbi State were analysed to determine the levels of poisoning caused by toxic metals such as Cd, Cr, Pb, Ni, Mn, Fe and Cu from the organs of those fresh fishes using Atomic Absorption Spectroscopy. The mean concentration of Cr 0.354 ppm, 0.343 ppm and Mn 0.263 ppm, 0.230 ppm in both flesh and gills of the fresh fish respectively were higher than the WHO permissible limit of 0.01 ppm Cr and 0.05ppm Mn, while the others were within the tolerable limits. However, the mean concentration of Cr and Mn were high against that of Cd 0.006 ppm, 0.007 ppm and Pb 0.019 ppm, 0.029 ppm in flesh and gills of the fresh fish respectively. It is here recommendation that people should be enlightened on the health implication of these toxic metals. An effective waste management plan should also be developed and implemented in the area to reduce/eliminate the impact of these toxic metals on the environment.
