Corn products were acquired from markets and supermarkets in the city of Campinas, SP, Brazil, and were analysed of FB1 and FB2. Among 81 samples, 40 were positive for FB1 (0.03-4.93 mg/kg) and 44 were positive for FB2 (0.02-1.38 mg/kg). The samples, in order of decreasing contamination were corn meal followed by degerminated corn, corn flour, precooked corn flour, corn grits and popcorn. Relatively lower incidences and levels of contamination were found in corn flakes are corn flour baby cereal. The samples of corn on the cob and of the typical foods curau and pamonha, both prepared with corn in the milky stage, did not show any detectable contamination. Canned sweet corn, also harvested in the milky stage, exhibited a very low incidence of and level of contamination. This is the first report on fumonisins in Brazillian corn based food products.
