Abstract
Samples of maize from discolored spots in the surface layer of stored grain in a southeast Missouri bin were examined for variation in microbial profile and for the presence of aflatoxin. Comparisons were made with samples of non-discolored maize from the same bin. Deteriorated test kernels showed a high incidence of Penicillium, Absidia, Mucor, Rhizopus and Fusarium spp., as well as bacteria and yeasts. Aspergillus species were also frequently observed; A. flavus was the most common species in this group. In one sample of discolored maize 80 per cent of the kernels contained A. flavus and the sample had 0·40 ppm aflatoxin B 1. Other fractions exhibited extensive discoloration but no aflatoxin.
