Our aim were to establish the metal (Cu, Ni, Zn, Co, Cd, and Pb) levels of red fox liver and the kidney samples (n = 10) deriving from central part of Hungary and compare the results with other countries’ data. According to our results the concentrations of residues of the targeted elements (mg/kg dry weight) in liver and kidney samples were, respectively in liver: Cu: 21.418, Zn: 156.928, Ni: 2.079, Co: 1.611, Pb: 1.678 and Cd: 0.499; and kidney samples: Cu: 9.236; Zn: 87.159; Ni: 2.514; Co: 2.455; Pb: 2.63 and Cd: 0.818. Pb levels of Hungarian red fox liver samples significantly exceed the values of Italian specimens’ samples, whilst the same element’s concentrations of Hungarian red fox kidney samples were higher than the results published in Germany.
