Abstract

The presence of mycotoxins in corn-based foods available in Argentina was determined in order to make a preliminary exposure assessment. Thirty-eight samples [corn meal ('polenta') and corn flakes] of different local brands were analysed for zearalenone, deoxynivalenol and aflatoxins by TLC and fumonisins (FB1, FB2 and FB3) by HPLC. None of the 38 samples contained any detectable amount of aflatoxins (<2mug g),="" zearalenone=""><50mug g)="" and="" deoxynivalenol=""><50mug g).="" by="" contrast="" fumonisin="" contamination="" was="" found="" in="" 95%="" of="" the="" samples.="" the="" highest="" fumonisin="" levels="" were="" found="" in="" corn="" meal:="" fb1(range="" positives:="" 60-2860mug/kg;="" mean="" positive="" value:="" 556mug/kg),="" fb2(61-1090mug/kg;="" 232mug/kg)="" and="" fb3="" (18-1015mug/kg="" 150mug/kg).="" low="" levels="" of="" fumonisin="" b1="" were="" detected="" in="" 16/17="" corn="" flakes="" samples="" (2-38mug/kg).="" total="" fumonisin="" levels="" in="" corn="" mealwere="" more="" than="" 1000mug/kg="" in="" 24%="" (5/21)="" of="" the="" samples.="" although="" it="" is="" not="" the="" staple="" food="" in="" argentina,="" maize="" consumption="" is="" very="" important,="" especially="" among="" children.="" a="" daily="" fumonisin="" intake="" of="" 11.="" 3mug/kg="" of="" body="" weight="" was="" estimated="" for="" child="" consumers="" (1-5="" years="" old)="" based="" on="" an="" average="" consumption="" of="" 200g="" of="" corn="" meal/day.="" calculated="" atan="" averageratefor="" allchildren="" (consumers="" or="" not)="" the="" intake="" estimate="" was="" 0.9mug/kg="" of="" body="" weight.="">
