In this study, ten Fusarium toxins were analysed in wheat and maize commodities from Albania. In total, 71 samples of wheat and 45 samples of maize were collected from different producing regions. The analytical procedure consisted of a simple one-step sample extraction followed by the determination of toxins using liquid chromatography coupled with tandem mass spectrometry. Fusarium toxins were found in 23% of the analysed wheat samples and in 78% of maize samples. In maize samples, most often fumonisins B1 (FB1) and B2 (FB2) were found. They were present in 76% of samples. They were detected in all positive samples except in one with concentrations ranging from 59.9 to 16,970 μg/kg. The sum of FB1 and FB2 exceeded the EU maximum permitted level (4000 μg/kg) in 31% of maize samples. In wheat samples, the only detected Fusarium mycotoxin was deoxynivalenol (DON), present in 23% of samples. In one sample with the concentration of 1916 μg/kg, the EU maximum permitted level (1250 μg/kg) was exceeded. This is the first report on the presence of Fusarium toxins in wheat and maize grains cultivated in Albania.

The influence of ozone (O3) gas on reducing the contamination with Fusarium mycotoxins in malting wheat grains was investigated. Ultra-high performance liquid chromatography coupled to triple quadrupole tandem mass spectrometry (UHPLC-QqQ-MS/MS) and Orbitrap high resolution mass spectrometry (UHPLC-Orbitrap-HRMS) were used to determine mycotoxins in wheat grains before and 40 to 130 min after the exposure to 20 mg/l O3. Pearson’s analysis (R2=0.96-0.98) showed a good correlation between the performance efficiency of both mass spectrometry quantification techniques. The concentrations of determined mycotoxins (zearalenone (ZEA): 19.5-459 µg/kg, deoxynivalenol (DON): 3,370-4,620 µg/kg, T-2 toxin: 19.5-35.4 µg/kg, and HT-2 toxin: 258-819 µg/kg) decreased notably, depending on the duration of contact with ozone. A notable elimination of ZEA, HT-2, and T-2 in wheat grain was observed: the content of these compounds was reduced on average by 58.6, 64.6, and 62%, respectively, already after 40 min of ozonation. The effect was less pronounced in the case of DON, for which the average degradation rate reached the maximum of only 25% after 130 min exposure. We conclude that ozonation for up to 130 min was effective for reducing the content of most mycotoxins determined in this study, except for DON, in contaminated grains to concentrations below the acceptable maximum levels in wheat in accordance to the EU regulations.
