    The objective of this study was to quantitatively determine the concentration of cadmium, lead, and copper in bovine liver sold at the Central Market, 03 de Febrero, and the Yerbateros Slaughterhouse during September 2014. The method used for the quantification of these metals was Atomic Absorption Spectrophotometry with a graphite furnace. The cadmium levels found in the twenty-five liver samples showed an average of 9.59 mg Cd/kg liver, with a minimum value of 5.89 mg/kg and a maximum value of 14.11 mg/kg. Lead levels in the samples showed an average of 52.26 mg Pb/kg liver, with a minimum of 28.34 mg/kg and a maximum of 75.85 mg/kg. Finally, copper levels in the samples showed an average of 1.70 mg Cu/kg liver, with a minimum of 0.78 mg/kg and a maximum of 3.09 mg/kg. The results indicate that the bovine liver samples exceed the established cadmium, lead, and copper limits according to the Official Mexican Standard and European Union regulations. Therefore, it is concluded that the liver samples contain Cd, Pb, and Cu above the permitted levels according to international standards, posing a potential health risk for consumers.
