title: Fumonisins in corn (Zea mays L.) from Southern Brazil.
abstract: A total of 232 samples of corn commercialised in Santa Catarina state, Southern Brazil (temperate zone climate), were evaluated from 2007 to 2012 for fumonisins (FBs: FB1 and FB2). Before performing this study, a FBs method with liquid chromatography and fluorescence detection (ex. 335; em. 440 nm) was validated first. FBs were detected in 46.6% (108 samples), with values ranging from 66 to 7832 µg kg(-1) for FB1 and 110 to 1201 µg kg(-1) for FB2. The number of contaminated corn samples for FB1 and FB2 varied and often presented contamination of FB1 only. Per year of analysis, the numbers were: n = 22/8(FB1/FB2), 44/5(FB1/FB2), 25/12(FB1/FB2), 4(FB1), 6(FB1) and 7(FB1) in 2007, 2008, 2009, 2010, 2011 and 2012, respectively. The contamination percentage was 42.3/15.4, 59.5/6.8, 43.8/21.1, 36.4, 35.3 and 33.3%, respectively, during these years. Consumers can be exposed to these mycotoxins and their health can be at risk through the consumption of contaminated corn.
