The effect of ochratoxin A in feed for pigs, and the incidence of its residue in liver and kidney were investigated. The samples were taken from farms and corresponding slaughterhouse in different areas of Serbia. The criteria for OTA residue examination in the mentioned tissues were macroscopic alterations in kidneys, that is a marked kidney ischemia. 14 feed samples, 12 kidney samples and 12 liver samples in total were examined. The average OTA concentration in feed was 25,24 g/kg (0,0-85 g/kg). The presence of the OTA residue was found in all of examined tissues samples. The average OTA concentration in kidneys was 2,37 g/kg (1,0-8,2 g/kg), in liver was 2,66 g/kg (1,2-5,5 g/kg). The experiment showed that the average OTA concentration in feed of farm A in contrast to farm B was significantly low (p < 0,05), in liver was significantly lower (p < 0,01), while in kidneys was not significantly low (p < 0,05). The correlation between these three findings was postulated and discussed.
