Sesame seed is one of the main nutrient substances which is used in the food industries of Khorasan Razavi, Iran. Because it is likely that stored sesame seeds are contaminated with mycotoxins, the levels of aflatoxins (AF) in five lots of imported sesame seeds before their distribution to the market were studied during one year. A total of 269 sub-samples were obtained from a total of 9,321 tons of sesame seeds from five importing companies. Aflatoxins at >1 μg/kg were found in 50 % of all samples, but at low levels in most cases, which is illustrated by mean AFB1 and total AF levels of 1.25 ± 3.70 and 1.43 ± 4.38 μg/kg, respectively. A few (1.9 %) samples exceeded the National Iranian Standard maximum accepted level for AFB1 (5 μg/kg) or total AF (15 μg/kg); the maximum total AF level found in one sample was 48 μg/kg. The results indicate that the risk of a violative AF contamination in imported sesame seeds is not negligible but is currently relatively low.
芝麻籽是伊朗霍拉桑拉扎维省食品工业的主要营养物质之一。由于储存的芝麻籽很可能受到霉菌毒素的污染，因此在将其分发到市场之前，对 5 批进口芝麻籽的黄曲霉毒素（AF）水平进行了为期一年的研究。从 5 家进口公司的 9321 吨芝麻籽中总共获得了 269 个次级样本。所有样本中，有 50%的样本中发现了 >1μg/kg 的黄曲霉毒素，但大多数情况下含量较低，这表明 AFB1 和总 AF 的平均值分别为 1.25±3.70μg/kg 和 1.43±4.38μg/kg。少数（1.9%）样本超过了伊朗国家标准规定的 AFB1（5μg/kg）或总 AF（15μg/kg）的最大允许水平；在一个样本中发现的最高总 AF 水平为 48μg/kg。结果表明，进口芝麻籽中黄曲霉毒素污染超标风险不可忽视，但目前风险相对较低。
