The aim of this study was to determine the cadmium concentration in four muscles and 10 edible offal items of 15 free-range reared Swallow-belly Mangulica pigs from Vojvodina, by flame atomic absorption spectrometry after mineralisation by dry ashing. All individual concentrations in muscles and heart, tongue, spinal cord, back fat and leaf fat were below the limit of detection (LOD = 0.050 mg/kg). In lungs, spleen and brain, cadmium concentrations ranked from below LOD, 0.055 and 0.058 to 0.057, 0.065 and 0.074 mg/kg, respectively. The concentration of cadmium in liver and kidney ranged from 0.089 to 0.116 mg/kg and from 0.204 to 0.440 mg/kg, respectively. Cadmium concentrations in liver and kidney of free-range reared Swallow-belly Mangulica pigs slaughtered at about 20 months of age were lower than in liver and kidney of commercial pigs from Vojvodina, slaughtered at about 6 months of age.
