中文摘要：在尼日利亚，玉米、高粱和小米是重要的经济作物，每天在不同的文化背景下以不同的加工形式被消费。这些作物易受真菌感染，从而受霉菌毒素污染。本研究从尼日利亚四个不同的农业生态区随机选中的市场中收集了玉米（136）、高粱（110）、小米（87）和ogi (30)总共363个样品，用多种霉素毒素液相色谱串联质谱(LC-MS/MS)法分析镰刀菌毒素污染的情况，随后选取了部分样品分析隐蔽的伏马菌素的发生情况。结果表明，谷物和谷物制品，特别是婴儿食品ogi，可能是镰刀菌毒素的暴露源。
外文摘要：In Nigeria, maize, sorghum, and millet are very important cash crops. They are consumed on a daily basis in different processed forms in diverse cultural backgrounds. These crops are prone to fungi infestation, and subsequently may be contaminated with mycotoxins. A total of 363 samples comprising of maize (136), sorghum (110), millet (87), and ogi (30) were collected from randomly selected markets in four agro-ecological zones in Nigeria. Samples were assessed for Fusarium mycotoxins contamination using a multi-mycotoxin liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Subsequently, some selected samples were analysed for the occurrence of hidden fumonisins. Overall, 64% of the samples were contaminated with at least one toxin, at the rate of 77%, 44%, 59%, and 97% for maize, sorghum, millet, and ogi, respectively. Fumonisins were the most dominant, especially in maize and ogi, occurring at the rate of 65% and 93% with mean values of 935 and 1128 μg/kg, respectively. The prevalence of diacetoxyscirpenol was observed in maize (13%), sorghum (18%), and millet (29%), irrespective of the agro-ecological zone. Other mycotoxins detected were deoxynivalenol, zearalenone, and their metabolites, nivalenol, fusarenon-X, HT-2 toxin, and hidden fumonisins. About 43% of the samples were contaminated with more than one toxin. This study suggests that consumption of cereals and cereal-based products, ogi particularly by infants may be a source of exposure to Fusarium mycotoxins.
