The objective of this study is to determine the occurrence and level of aflatoxins (AFs) contamination in freshly harvested maize for human consumption in rural Kenya. Maize kernels and freshly milled maize flour (n = 338) were collected from households in Siaya and Makueni counties. While both counties are representatives of different environmental and climate conditions, Makueni County is the...

Aflatoxin M1 (AFM1) contamination in 150 samples of milk, sold in market of Hisar city of Haryana, India, was investigated by using High Pressure Liquid Chromatography (HPLC). Out of these, 40 samples contained AFM1 at a concentration below the limit of detection (LOD) of 0.052 μg/kg. Among the AFM1 contaminated samples, 46 raw milk samples contained a concentration above the LOD but less than...
