Abstract

The goal of this survey was to evaluate the presence and concentration as well as the co-occurrence of legislated and non-legislated mycotoxins in wheat flour samples from Brazil. A total of 200 wheat flour samples were analysed by a validated multi-mycotoxins method. DON was the mycotoxin with the highest occurrence, being present in 100% of the analysed samples and showing contamination in both years and regions (53–2905 μg kg−1). ZEN was detected in 51% (<LOQ–50 μg kg−1) of the samples, while T-2 (not legislated in Brazil) was detected in 13.5% (<LOQ–1506 μg kg−1) of all samples. Regarding co-occurrence, all samples were contaminated with two to three mycotoxins.
