摘　　要：Aflatoxins and fumonisins contaminate cereals during pre-and post-harvest periods.In this study,household or market maize,sorghum,millet,cow or goat milk,and animal feed samples collected from two counties(Makueni and Nandi)of Kenya and were analyzed for aflatoxins and fumonisins using competitive enzyme-linked immunosorbent assay and confirmation with high performance liquid chromatography.There was a significant difference(P<0.005)in the levels of aflatoxins between the home grown and market-sourced maize,sorghum,and millet samples.In Makueni,24.8%of home maize and 44.6%of the market maize samples exceeded the 10 ppb limit for aflatoxins.In all,93%and 90%of the maize samples were contaminated with fumonisins and 34%and 6%exceeded the 2 ppm limit in Makueni and Nandi,respectively;30%and 37%of homegrown sorghum and millet samples exceeded the 10 ppb limit for aflatoxin in Makueni and Nandi,respectively;and 89%and 81%of homegrown millet samples in Makueni and Nandi,respectively,were positive for fumonisins and 22%and 7%in Makueni and Nandi,respectively,exceeded the 2 ppm fumonisins limit.In total,52%and 87%of the milk samples in Nandi and Makueni,respectively,were contaminated with aflatoxin M1 and 8%of the samples from Makueni exceeded the 50 ppt limit.There is an urgent need to build capacity among the households on cheap,practical,and effective technologies that would reduce the proportions of food samples contaminated with aflatoxins and fumonisins.
