The mycoflora and mycotoxins contamination of commercial maize and rice grains collected from local markets of the major five zones of the province of Cairo, Egypt, represented by 20 different districts were studied. A total number of about 23 species belonging to 12 different genera of fungi were isolated and identified. About 70% of the samples were infected with Aspergillus flavus and Aspergillus niger, with percentages of 33%, 40% recovered from maize and 46%, 27% recovered from rice, respectively. The percentages of infection of maize ranged from 16% to 142%. The percentages of infection of rice seeds ranged from 6% to 93%. Total aflatoxins and fumonisins detected in maize averaged 9.75 and 33 µg/kg, respectively. Total aflatoxins and fumonisins detected in rice averaged 5.15 and 1014 µg/kg, respectively.
对从埃及开罗省五个主要地区的当地市场上采集的商业玉米和大米谷物的真菌区系和霉菌毒素污染进行了研究。共分离鉴定出约 23 种属于 12 个不同属的真菌。约 70%的样品受到黄曲霉和黑曲霉的感染，分别从玉米和大米中回收了 33%和 40%的比例，从玉米和大米中回收了 46%和 27%的比例。玉米的感染率从 16%到 142%不等。水稻种子的感染率从 6%到 93%不等。玉米中检测到的总黄曲霉毒素和伏马菌素分别平均为 9.75 和 33μg/kg。大米中检测到的总黄曲霉毒素和伏马菌素分别平均为 5.15 和 1014μg/kg。
