The objective of this study was to evaluate the possible bioaccumulation of certain heavy metals – namely Lead (Pb) and Cadmium (Cd) -in the internal parts of chickens. A total of 80 chicken muscles, kidney, liver and gizzard samples (20 of each) were randomly collected from different chicken farms, in Omdurman locality- Sudan. Water samples were also obtained from the water reservoir in each farm. Then wet digestion of samples was done followed by the use of Atomic Absorption Spectrometer (AAS) to measure the level of Pb and Cd. The two heavy metals were found to be present in all studied parts of the chickens. The concentration of Cd varies significantly within the poultry tissue but fall within the permissible limits for meat consumption set by the FAO and Sudanese Standards and Metrology Organization (SSMO). The mean values of Cd were 0.013 ±0.001μg/g, 0.033±0.002μg/g, 0.028 ± 00.005μg/g and 0.037±0.003μg/g, in muscles, kidneys liver and gizzard respectively. The concentration of Cd in water was 0.0031±0.003μg/l which was within the permissible limits. The level of Pb varied significantly within the poultry tissue but was above the permissible limits. The mean values of Pb in gizzard was the highest followed by kidney then liver and the least concentration was detected in muscles 0.224±0.013μg/g, 0.295±0.007μg/g,0.266±0.014μg/g and 0.350±0.026μg/g respectively, while the concentration in water was 0.150±0.006μg/ and was also higher than the permissible limits. Precocious steps must be taken to monitor and reduce the concentrations of lead in water and feed used by poultry farmers. Also governmental efforts are needed to control the environmental pollution which may be an additional source for contamination.
