ABSTRACT
In Iran, maize is cultivated in wide areas including northern provinces. It is one of the most important crops for poultry and livestock feeding, which is susceptible to aflatoxins [AFs] contamination. So, pre-harvest maize samples from Mazandaran province, north of Iran were analyzed for AFs contamination. Thirty-five pre-harvest maize samples were analyzed using immunoaffinity column and reversed-phase liquid chromatography with post-column derivatization. Data revealed that incidence of AFB1, AFB2 and total aflatoxins [AFT] in maize samples were 66%, 54% and 63% with mean of 9.5 +/- 16.3, 1.7 +/- 2.6 and 10.4 +/- 18.4 ng/g, respectively. The mean level of AFB1 in samples was higher than the Iranian maximum tolerated level [MTL]. But, AFT mean level [10.4 ng/g] was lower than the Iranian and US [20 ng/g] MTLs
