ABSTRACT
Heavy metals can enter into food chain including chicken meat; indeed, several studies have reported their notable concentration in chicken parts. There is enormous consumption trend of broiler chicken in Saudi Arabia, which indicated the requirement of regular screening for possible toxic contaminants. In this investigation, level of seven trace elements in broiler chicken parts collected from Jazan region was measured by ICP-MS. The level of heavy metals were in the range of 0.01-0.04, 0.12-0.59, 1.15-6.32, 12.21-76.41, 0.13-1.63, 0.26-0.60 and 11.28-103.67 mg/kg for Cd, Cr, Cu, Fe, Ni, Pb and Zn, respectively. Results showed that the essential elements such as Fe and Zn detected in higher concentrations as compared to non-essential and toxic elements including Pb and Cd. The results of health-risk assessment showed that intake of heavy metals through consumption of broiler chicken in the tested region is unlikely to pose obvious adverse effects to the consumer population (THQ˂1).
