The natural occurrence of fumonisin B1 (FB1) and its co-occurrence with zearalenone (ZEA), T-2 toxin and deoxynivalenol (DON) were surveyed in 103 winter wheat samples collected after four to six-month storage in family barns from different locations in Serbia. All 103 samples were mycotoxin positive. The mean concentrations of all mycotoxins except ZEA were greater in 2005 than in 2007. FB1 was detected in 82.1% and 92.0% of all samples with ranges of 750–5400 μg kg−1(mean, 2079.45 μg kg−1) and 750–4900 μg kg−1(mean 918.76 μg kg−1) in 2005 and 2007, respectively. Moderate positive correlations were found between FB1 and DON concentrations (r = 0.56 in 2005 and r = 0.54 in 2007) and between FB1 and ZEA concentrations (r = 0.48 in 2005 and r = 0.60 in 2007), while a moderate negative correlation was detected between the production of FB1 and T-2 toxin in 2007 (r = −0.33). This is the first report of FB1 occurrence in naturally-contaminated wheat grain and its simultaneous occurrence with ZEA, DON and T-2 toxin in Serbia. Moreover, this is one of the rare reports presenting the occurrence of FB1 on wheat in the world.
