Samples of corn belonging to 19 cultivars with distinct types of germoplasms, endsperm and length of vegetative cycle, were analysed for FB1 and B2. The cultivars were grown in experimental fields in three locations within the State of Sao Paulo, Brazil, during the 1997/1998 crop. All 23 samples were contaminated with fumonisin,with concentrations of FB1 ranging from 1.63 to 25.69 mg/kg with an average of 5.61 mg/kg and of FB2 from 0.38 to 8.60 mg/kg with an average of 1.86 mg/kg. In terms of fumonisins, these high levels put the corn cultivated in Sao Paulo among the most contaminated in the world reported to date.
