Meat comprises the main part of the diet in many countries around the world. The present study aimed to assess potentially toxic elements (PTEs) lead (Pb), arsenic (As), cadmium (Cd), copper (Cu), nickel (Ni), zinc (Zn), and iron (Fe) in various meats (camel, chicken, cow, pork, birds, seafood (fish and crab), and sheep). The present study was performed on the concentration of PTEs in various meats by different databases including Scopus, PubMed, and Web of Science along with a meta-analysis. Additionally, the non-carcinogenic risk was assessed by calculating the total hazard quotient (TTHQ). According to findings, the highest concentration of Cd was related to sea (0.460 mg/kg). The highest concentrations of Cd and As were reported in camel meat (1.965 and 1.503 mg/kg, respectively). Regarding trace elements, the highest concentrations of Zn, Fe, Cu, and Ni were observed in seafood (fish and crab), cow meat, and bird’s meat (71.159 mg/kg, 36.608 mg/kg, 8.680 mg/kg, and 1.592 mg/kg, respectively). Moreover, considering the type of continents based on the concentration of PTEs in various meats, the highest concentrations of As (0.792 mg/kg), Cd (0.315 mg/kg), Pb (1.049 mg/kg), Fe (44.088 mg/kg), and Ni (1.113 mg/kg) were related to Eastern Mediterranean region (EMRO), African Region (AFRO), EMRO, the Pan American Health Organization (PAHO), and EMRO, respectively. However, the highest concentrations of Cu (4.846 mg/kg) and Zn (60.742 mg/kg) were related to European Region (EURO) and AFRO, respectively. On the other hand, the result of the risk assessment indicated that the risk pattern was different among countries.
