Past surveys indicated that the occurrence of aflatoxins, zearalenone (ZEA) and OA was not a problem in corn and corn products in the state of Sao Paulo, Brazil. However, in recent studies, a change in pattern was observed. A total of 110 samples of freshly harvested corn, corresponding to 48 commercial cultivars planted at three different locations in the state, were assayed. Aflatoxin B1 contamination was found in 60 / 110 samples at levels ranging from 6 to 1600 mg/kg. OA was found in two samples (206 and 128 mg/k) and ZEA in one sample (4640 mg/kg). Possible causes of the increase in aflatoxin levels are discussed.
