The goal of this work is to provide adequate information about the mould associated with dry maize samples in Okitipupa metropolis and also generate data which will give an insight into management and prevention of mycotoxicoses outbreaks in the region. Dry maize (Zea mays) was obtained randomly from selected rural households and markets within Okitipupa, Ondo state, Nigeria. Moulds were isolated from all the samples with at least one genera of mycotoxigenic fungi present such as; Aspergillus, Fusarium and Penicillium. The frequently occurring mould species were; Aspergillus flavus, Aspergillus tamarii, Aspergillus niger, Aspergillus fumigatus, Aspergillus terreus, Fusarium oxysporum, Fusarium proliferatum and Penicillium atramentous. The occurrence of A. flavus was the highest in all the samples collected followed by Fusarium proliferatum and Fusarium oxysporum. Penicillium has the lowest frequency of occurrence. The highest occurring mould species were Aspergillus flavus (40%), Aspergillus tamarii (20%), Aspergillus niger (4%), Aspergillus fumigatus (4%), Aspergillus terreus (4%), Fusarium oxysporum (12%), Fusarium proliferatum (16%) and Penicillium (4%).
Key words: Maize, toxigenic mould
