45 random samples of imported frozen meat were collected from Al-Gharbiah markets, Egypt. The collected samples were represented by Brazilian, Columbian and Indian meat (15 of each). The collected samples were examined for cadmium, lead and mercury concentrations on the basis of wet weight (mg/kg) by Atomic Absorption Spectrophotometer (AAS). The obtained results revealed that the mean concentrations of cadmium in the examined samples of imported frozen Brazilian, Columbian and Indian meats were 0.06 + 0.01 mg/kg; 0.14 + 0.01 mg/kg and 0.19 + 0.01 mg/kg, respectively, while the mean concentrations of lead in the examined samples of imported frozen Brazilian, Columbian and Indian meats were 0.35 + 0.02, mg/kg; 0.41 + 0.02 mg/kg and 0.52 + 0.03 mg/kg, respectively , concerning to mercury it could not be detected in the examined samples of imported frozen Brazilian meat, while the mean concentrations of mercury in the examined samples of imported frozen Columbian and Indian meats were 0.20 + 0.01 mg/kg and 0.37 + 0.02 mg/kg, respectively. Comparing the results to the maximum permissible limits stated by the Egyptian Organization of Standardization "EOS" (2005), found thatthe examined imported frozen Indian meat contained the highest residual concentration of heavy metals (cadmium, lead and mercury) followed by Columbian and Brazilian. |
