Corn samples and different dry-milled fractions collected from an industrial mill in Argentina were analysed. Average contaminations were FB1 1540 micrograms kg-1, FB2 716 micrograms kg-1 and FB3 152 micrograms kg-1 in whole corn; FB1 135 micrograms kg-1, FB2 39.1 micrograms kg-1 and FB3 10.2 micrograms kg-1 in corn grits; FB1 358 micrograms kg-1, FB2 122 micrograms kg-1 and FB3 45.9 micrograms kg-1 in 'C' flour; FB1 148 micrograms kg-1, FB2 52.5 micrograms kg-1 and FB3 28.3 wg micrograms-1 in corn meal; and FB1 4210 micrograms kg-1, FB2 2010 micrograms kg-1 and FB3 447 micrograms kg-1 in germ and bran together. The fumonisin contamination level was approximately three times higher in germ and bran than in whole corn, 13 times higher than in 'C' flour and 29 times higher than in corn meal and corn grits. Taking into account the distribution of fumonisins in commercial dry-milled corn fractions and corn meal consumption in Argentina, a theoretical whole corn level of 6640 micrograms kg-1 maximum of total fumonisins could be processed to obtain products considered safe for human health.
