Corn collected in the Mazandaran and Isfahan Provinces of Iran was analyzed for fumonisin B(1) (FB(1)), fumonisin B(2) (FB(2)), and fumonisin B(3) (FB(3)). The samples from Mazandaran Province, situated on the Caspian littoral of Iran, were random samples from farmers' corn lots collected in September 1998, whereas those from Isfahan Province, situated further south in the center of Iran, were bought as corn cobs in the local retail market during October 1998. All 11 samples from Mazandaran showed high levels of fumonisin contamination with FB(1) levels between 1.270 and 3.980 microg/g, FB(2) levels between 0.190 and 1.175 microg/g, and FB(3) levels between 0.155 and 0.960 microg/g. Samples from Isfahan showed lower levels of contamination with eight of eight samples having detectable FB(1) (0.010-0.590 microg/g), two of eight samples having detectable FB(2) (0.050-0.075 microg/g), and two of eight samples having detectable FB(3) (0.050-0.075 microg/g). This is the first report of fumonisin contamination of corn from Iran, in which samples from the area of high esophageal cancer on the Caspian littoral have been shown to contain high levels of fumonisins.
对在伊朗马赞德兰省和伊斯法罕省采集的玉米进行了伏马毒素B1（FB1）、伏马毒素B2（FB2）和伏马毒素B3（FB3）的分析。来自伊朗里海沿岸的马赞德兰省的样本是1998年9月从农民的玉米批次中随机抽取的，而来自伊朗中部更南部的伊斯法罕省的样本是1998年10月在当地零售市场作为玉米棒购买的。马赞德兰省的所有11个样本都显示出高水平的伏马毒素污染，FB1水平在1.270至3.980微克/克之间，FB2水平在0.190至1.175微克/克之间，FB3水平在0.155至0.960微克/克之间。伊斯法罕省的样本污染水平较低，8个样本中有8个可检测到FB1（0.010 - 0.590微克/克），8个样本中有2个可检测到FB2（0.050 - 0.075微克/克），8个样本中有2个可检测到FB3（0.050 - 0.075微克/克）。这是关于伊朗玉米伏马毒素污染的首次报告，其中里海沿岸食管癌高发地区的样本已被证明含有高水平的伏马毒素。
