Fumonisin B1, zearalenone, deoxynivalenol and T-2 toxin content of harvested and stored maize samples from Hungary collected during Dec. 1993-Feb. 1994, were determined by HPLC. Of the mouldy maize samples collected after a period of storage, 70.8% contained fumonisin B1 (0.05-19.8 mg/kg, mean concn 2.6 mg/kg), 87.5% contained zearalenone (0.01-11.8 mg/kg, mean concn 1.26 mg/kg), 70% contained vomitoxin (0.07-21.2, mean concn 4.33 mg/kg) and 41.7% contained T-2 toxin (0.06-0.39, mean concn 0.2 mg/kg). These mycotoxins often occurred together in the samples. In the non-mouldy samples, both the positivity rate and the mycotoxin concn were markedly lower. In the harvesting period, the mycotoxin content of maize ears affected by moulds ("affected sample") and of the "average sample" was determined separately for each maize-field involved in the study. Of the affected samples, 70% contained fumonisin B1 (0.095-52.4 mg/kg; mean 6.64 mg/kg), 17% contained zearalenone (0.006-0.079 mg/kg; mean 0.03 mg/kg), 13% contained vomitoxin (0.05-0.118 mg/kg; mean 0.09 mg/kg) and 39% contained T-2 toxin (0.05-0.551 mg/kg; mean 0.165 mg/kg). Fumonisin B1 and T-2 toxin often occurred together in the affected maize samples. Of the "average samples", 30% were contaminated with fumonisin B1 (0.06-5.1 mg/kg; mean 1.52 mg/kg) and 9% with T-2 toxin (mean 0.05 mg/kg).
