Determination of some heavy metals resides in different types of poultry production

Abstract

The diet is the main rout of exposer of heavy metals; therefore the evaluation of these metals in human’s dietary intake is important. The study examined the concentration of some residues of heavy metals (copper, Arsenic and Lead ) in different poultry products such as chicken frozen thigh and breast muscle originating from Brazil and Turkey, Etimad and Shemal local company chicken frozen thigh and breast muscle, local quail frozen thigh and breast muscle as well as local quail eggs. The results of the study indicated that the highest concentrations of Copper (Co) and Arsenic ( As) were found in Brazilian frozen thigh and breast muscles compared with other products. However, the concentrations of these metals were within permissible and safe for human consumption. Lead (Pb) concentrations chicken frozen thigh and breast muscle originating from Brazil was found to be high (p≤0.05) and above permissible level than chicken and quail frozen meat as well as eggs.
