Abstract: Heavy metals are persistent in the environment and are subject to bioaccumulation in food chains. However, exposure does not result only from the presence of a harmful agent in the environment. The present study was undertaken to investigate the concentrations of heavy metals (Zn, Cr, Pb, and Cu) in some organs and tissue such as blood, bones muscle and liver of local chicken sold in Mubi. Heavy metals were determined by standard methods of atomic absorption spectroscopy (AAS). One way analysis of variance (ANOVA) was used to analyze the data followed by Duncan multiple range test (DMRT) for means separation. The concentration of the above heavy metals in the studies samples were found to be significant, they are generally above the tolerance limit set by WHO, CODEX and FAO. Therefore consumption of free range local breed of chickens in Mubi has the danger of ingestion of heavy metals.
