Wheat, barley and oat grain samples naturally contaminated withFusariumspp. were analysed for the presence of scirpentriol (STO). This toxin was detected in 1, 37 and 8% of 248 wheat, 32 barley and 99 oat grain samples, respectively, and the maximum concentration was 83 µg kg−1. Samples of wheat and oat grain with visible scab symptoms were also analysed, and STO (mean level 255 µg kg−1) was detected only in oat samples infected withF. sporotrichioidesandF. poaeas the dominant species. We analysed 15 barley samples that were subdivided based on seed size into fractions of <2.5 and > 2.5 mm in diameter. The smaller kernels contained an average 94% of the STO in the samples (in kernel fraction > 2.5 mm 28 µg kg−1, <2.5 mm 297 µg kg−1). In oats, STO levels were highest in the chaff, lower in the stalk's apical internode and lowest in the grain.
