Maize kernel samples were collected in 1996 from smallholder farm storages in a number of districts in the tropical highlands of western Kenya. Two-thirds of the samples were good quality maize, and one-third were poor quality maize with a high incidence of visibly diseased kernels. One hundred and fifty three maize samples were assessed for Fusarium infection. Fusarium moniliforme was isolated most frequently, but other Fusarium species were also isolated. Analysis of 197 maize kernel samples by HPLC found little FB1 in most of the samples. Forty seven percent of the samples contained FB1 at levels above the detection limit (100 µg/kg), but only 5% were above 1,000 µg/kg. Many samples with a high incidence of visibly diseased kernels contained little or no FB1 , despite the presence of F. moniliforme.
