Occurrence of fungi from the genus Fusarium depends on the effects of various climatic factors, and the production of fumonisin depends on weather conditions and the location of plantation. Climate data show changes in temperature and precipitation and may provide insight into their impact on fungal development and fumonisin production (FB1 and FB2). LC-MS/MS method for FB1 and FB2 determination was developed. Linearity of the method was in the range 10-400 ng/mL for FB1 and 3-120 ng/mL for FB2 with correlation coefficients R2 > 0.99. Limits of quantification were 25 mg/kg for FB1 and 7.5 mg/kg for FB2. Recovery was in the range from 87 to 96.7%, with method precision lower than 16%. The method was applied for analysis 36 samples, and in 19 were detected fumonisines FB1 and FB2 in concentrations over the limit of quantification. In three samples concentrations of FB1 and FB2 were over MRL set by EC/1881/2006 (sum FB1 and FB2 2000 mg/ kg), but lower than MRL set by our National regulation (4000 mg/kg).
