An examination of Fusarium toxins contamination in wheat, barley, and wheat flours

Abstract

The occurrence of deoxynivalenol (DON), nivalenol (NIV) and zearalenone (ZEN) was surveyed with domestic wheat, barley and wheat flours produced from domestic and imported wheat grains. Among the 31 samples examined, 4 wheat and 5 barley samples were positive for NW and 2 wheat samples were positive for DON. Neither ZEN nor multiple contamination of Fusarium toxins was detected in tested samples. Fusarium graminearum isolated from a wheat sample which was contaminated with NIV produced NIV on polished rice.
