Title: Heavy Metals in Selected Tissues of Adult Chicken Layers (Gallus spp)
Abstract: A study was conducted to determine heavy metals (As, Cd, Cr, Fe and Pb) in tissues (breast meat, gizzard, liver and kidney) of two layers ( Hacco and Isa Brown) species of adult chicken layer (Gallus spp). Sampling was carried out in two chicken layer farms in Maiduguri over a three months period (November 2012 – January 2013). Heavy metals were determined by the standard methods of inductively coupled plasma -optical emission spectrometry (ICP-OES). The results of the study reveal tha t As concentration is in the order: breast meat > kidney > gizzard > liver, Cd: kidney > gizzard > liver >breast meat, Cr: gizzard > breast meat > liver > kidney, Fe concentration in layer poultry tissues studied is: breast meat > gizzard > kidney > liver. Lead was not detected (ND) in all the samples analysed. The result of this study shows that the adult layer chickens are within safe limits for consumption. The information provided herein will be essential to frame guidelines and standards for heavy metals in feedstuff and meat products in Nigeria.
