Vietnamese coffee beans were investigated for the presence of ochratoxigenic Aspergilli. Ninety-three percent of the coffee samples studied were positive for A. niger. No other ochratoxigenic species were present. HPLC analysis determined that 8.7% of the A. niger strains were positive for ochratoxin A (OA) production. There was no significant difference in the level of contamination or incidence of toxigenic strains in samples that had been rejected by manual sorting and those that were destined for human consumption. No OA-producing fungi were uncovered in a fresh coffee bean sample analysed, suggesting that the OA problem most likely occurs post-harvest.
对越南咖啡豆进行了产赭曲霉毒素曲霉菌的检测。在所研究的咖啡样品中，93%对黑曲霉呈阳性。未发现其他产赭曲霉毒素的菌种。高效液相色谱分析确定，8.7%的黑曲霉菌株产赭曲霉毒素A（OA）呈阳性。经人工挑选剔除的样品和供人类食用的样品在污染水平或产毒菌株发生率上没有显著差异。在分析的新鲜咖啡豆样品中未发现产OA的真菌，这表明OA问题很可能发生在收获后。
