中文摘要：本研究中开展了一次有限样本规模的初步调查，旨在确定来自尼日利亚面粉厂和当地市场的小麦面粉中霉菌和真菌毒素的污染情况。本研究以14个小麦样品为对象，利用标准真菌学方法分析了其霉菌情况，并利用液相色谱串联质谱法分析了其有毒真菌代谢物。研究发现，样品中共检测到54种微生物代谢物，有四种是欧盟规定处理的霉菌毒素，其中，样品中主要的脱氧雪腐镰刀茵烯醇（发生率100%），其含量超过欧盟最高限量（750ug/kg）的36%。本报告强调需要进一步开展样本规模大、覆盖该国若干农业生态系统的强有力的调查。
外文摘要：A preliminary survey involving limited sample size was conducted to determine the spectrum of moulds and mycotoxins in wheat grains from flour mills and local markets in Nigeria. Fourteen wheat samples were analyzed for moulds using standard mycological methods and for toxic fungal metabolites using a liquid chromatography-tandem mass spectrometric method. Fusarium (range of incidence 12.5–61.7%) dominated in the wheat grains though species of Aspergillus (range of incidence 2.24–3.86%) were also recovered from the samples. The identified fungal species were Aspergillus flavus (7.7%), Aspergillus niger clade (2.6%), Fusarium avenaceum (10.9%), Fusarium culmorum (22.4%) and Fusarium graminearum (56.4%). A total of 54 microbial metabolites were detected in the samples at concentration ranging between 0.01 μg/kg for macrosporin and 2560 μg/kg for deoxynivalenol. Among the four mycotoxins addressed by regulations in the European Union (EU) found in the samples, deoxynivalenol (incidence 100%) dominated in the samples and its levels exceeded the maximum acceptable EU limit (750 μg/kg) in 36% of the samples. This report underscores the need for more robust surveys with larger sample sizes and across several agro-ecologies in the country.
