✦ Synopsis
toxin, diacetoxyscirpenol, and fusarenon-X were determined by gas chromatography, combined with mass selective detection (GC-MS), zearalenone, aand b-zearalenol by GC-MS or HPLC. Deoxynivalenol was the major toxin, with incidences of 68-95% and mean contents at 152-1,692 mg/kg. In contrast, incidences of zearalenone, 3-acetyldeoxynivalenol, nivalenol, HT-2 toxin, and T-2 toxin were at 11-80, 17-60, 25-64, 0-8, and 0-41%, respectively, with mean contents between 3 and 209 mg/kg. a-zearalenol and/or b-zearalenol were detected in five samples at contents #71 mg/kg; diacetoxyscirpenol was not detected in any sample. 15-acetyldeoxynivalenol and fusarenon-X were assayed in samples from 1987 and 1991-1993. 15acetyldeoxynivalenol was detected in 3-15% of samples at mean contents of 5-84 mg/kg; fusarenon-X was not detected. Over the years, incidences and levels of toxins remained constant, decreased or increased. The correlation between the occurrence of toxins and precipitation is discussed. Nat. Toxins 5:24-30, 1997.
