A mycological study was carried out on 11 samples of imported green coffee beans. Molds isolated from the green coffee beans have been identified. Mold flora of the green coffee beans consisted mainly of Aspergillus flavus, A. fumigatus, A. niger, A. tamarii, Eurotium herbariorum, Penicillium chrysogenum, and P. citrinum. Nine isolates of A. flavus were examined for aflatoxin production on rice and coffee bean media. Only one strain of A. flavus produced 1.1595 mg/kg and 58.69 μg/kg of aflatoxins on rice and coffee bean media, respectively. Existence of this caffeine-resistant aflatoxigenic strain would indicate that green coffee beans are not always the unfavorable substrate for aflatoxin production.
