ABSTRACT

The presence of fungi metabolite of toxin-producing strains of Aspergillus flavus collectively termedí aflatoxins in some garri and cassava flour samples was investigated using paper chromatography and iodine vapour for detection. All the samples screened were found to contain at least one aflatoxin. Garri samples collected from Ochanja market in Onitsha and Ogbete market in Enugu contained a maximum of three aflatoxins namely B1, B2, and G1. While, other samples collected from some other market contain a maximum of two aflatoxin.
