Based on a data of the Global monitoring of environment protection, food contamination and program of the mycotoxins risk assessment (GEMS/food, FAO, WHO), and also on data from national agencies for mycotoxins, we may say that their presence in food chain is very serious problem, especially in developing countries. Special risk for consumer health is possibility of mycotoxin residue presence in form of its metabolytes in foodstuffs of animal origin. Poultry meat consumption in Serbia is very important (17 kg/per capita/year), but in comparison to EU states, it is small. Considering that, the goal of this preliminary investigation is ascertainment of ochratoxin A residues (OTA) in regularly slaughtered broilers originating from different parts of Serbia, under the monitoring programme. Farms were selected from the regions with intensive poultry production, broilers were reared commercially, under the zootechnical recomendations for intensive breeding. Broilers were fed with normative based complete food mixtures of standard feed composition. During slaughtering procedure, following the random pattern, total of 90 samples of liver, gizzard and kidney were taken. OTA residues were determined by using the high efficient method of liquid chromatography with fluorescent detection (HPLC-FD). Presence of OTA residues in broiler tissues ranged from: 16,6% in gizzard, up to 25,6% in liver and kidneys 25,6%. Average concentrations in liver and kidney samples were identical. Relatively low values of standard deviation point the narrow interval in which OTA is present in tissues. The preliminary study results of OTA presence in broiler tissues points that actual concentration is generally very low, bellow recommended values of Scientifi c Committee of European Food Safety Authority (SC, EFSA) where tolerable daily intake (TDI) for OTA is BELLOW 5 ng/kg/body weight.
