Fifteen maize sample from four markets and processing sites in Accra, Ghana were analysed for fumonisins B1, B2, and B3. All sample contained fumonisins. Total fumonisin levels for 14 samples ranged from 70 to 4222 mg/kg. Mycological examination of the samples showed Aspergillus as the dominant genus (76.4%) followed by Penicillium (19.9%) Fusarium formed 2.6% Thirty-two Fusarium strains representing five species were isolated and tested for the production of fumonisins in maize substrates, From 21 of 22 F. verticillioides strains tested, all three types of fumonisins were produced, Additional studies on maize sample from 15 processing sited in Accra revealed a co-occurrence of both fumonisins and aflatoxins in 8/15 samples.
