The study was undertaken to determine the presence of mycotoxins in wheat flour from Serbia and to estimate the corresponding daily intake through consumption of wheat-based products by the general Serbian population. Fort his purpose, a total of 15 wheat flour samples were collected from markets during January 2011 year. Samples were analyzed for contamination with aflatoxins (AFs : AFB1, AFG1, AFB2, AFG2), ochratoxin A (OTA), trichothecenes (type A (HT-2,T-2 toxin) and type B (deoxynivalenol (DON))), zearalenone (ZON), fumonisins B1 and B2 (FBs: FB1 and FB2) by ultra-high performance liquid chromatography with heated electrospray ionization triple quadrupole mass spectrometry (UHPLC/HESI-MS/MS). The predominant mycotoxin was DON with an average value of 234 micro g/kg in 86.67% of analyzed samples. Furthermore, ZON and T-2 toxin were detected with a contamination frequency of 33.33% and 26.67%, respectively. The calculated daily intake of detected mycotoxins for the wheat flour estimated for average adult consumers on the base of Serbian market basket were compared with the tolerable daily intake (TDI) proposed by Scientific Committee on Food of the European Union.
