摘要:Wheat and other grain samples were separately analysed to identify the presence of fungi and their mycotoxins. The mycological profile of the retail in different markets at Riyadh (Kingdom of Saudi Arabia) was studied. Sixteen samples were collected from storage shops importer from Saudi Arabia. The most common genera were Alternaria (isolated from 68.96% of the tested samples), Aspergillus (24.14%) and in a lesser extent Fusarium (6.9%). Mycotoxin production by isolated fungi was subsequently evaluated using the High-Performance Liquid Chromatography Technique (HPLC). The present results indicate that mycotoxins with aflatoxin are widespread fungal contaminants of wheat. Therefore, their presence as well as the occurrence of mycotoxins should be further investigated to assess health risks linked with the consumption of this commodity.
