Abstract :

Poultry meat is considered as a source of animal protein with high biological amino acids, many vitamins, and minerals. Food contamination with heavy metals is a major threat to humans and animals. Long-term exposure could have detrimental effects. The aim of this study was to determine the concentration of lead in breast and liver tissues in poultry farms of Qom and Semnan provinces. A total of 50 samples of poultry production fields was randomly selected. After acid digestion, atomic absorption with the furnace was exploited to measure the lead concentrations. Based on statistical analysis, no significant difference was observed between the samples obtained from the two cities. Moreover, a significant (p < 0.05) difference was determined between the concentration of lead in the liver (0.40 ± 0.08 mg/kg) and breast tissue (0.28 ± 0.07 mg/kg) with the maximum allowance approved by the International Standard (0.1 mg/kg). The high levels of lead in the internal organs of the chickens could have originated from anthropogenic activities in the environment, contaminated feeds, and water fed to the chickens. Lead contamination in chicken is a potential public health hazard. Therefore, it is crucial to monitor the concentration of lead in poultry meat and offal.
