In view of the frequent occurrence of some mycotoxins in cereals, a study was initiated to obtain information for assessing the exposure of Hungarian adult population. The consumption figures of 1360 individuals based on 3-day record questionnaire indicated that the white bread amounted to the major proportion of intake of cereal based products. Various cereal products were analysed for 16 mycotoxins by a HPLC/MS/MS multi toxin method with LOD of 16 μg/kg and LOQ of 50 μg/kg. The deoxynivalenol (DON) was most frequently detected, but no acetyl-deoxynivalenol was present in detectable concentration. The exposure of consumers was calculated with standard Monte Carlo probabilistic modelling and point estimates, taking into account the bread consumption and DON contamination in independently taken wheat flour and wheat grain samples. Over 55% of cases the DON intake was below 15% of the PMTDI of 1 μg/kg bw/day. However, in about 5-15% of cases the intake from bread consumption alone exceeded the PMTDI. The wheat grain data led to the higher percentage. The intakes estimated from both data sets were at or below the ARfD of 8 μg/kg bw/day in 99.94%-99.97% of cases.
