Abstract

Studies were conducted to determine the incidences and levels of mycotoxin contamination in household stored maize and groundnuts in Kilosa District, Tanzania. Four villages were chosen for sampling. Seventy-two samples were collected from four villages in 2010, and then tested using a high-performance liquid chromatography method. Levels of Fumonisin B1 ranged from 63.26 to 213.15 μg/kg in all collected maize samples, while levels of aflatoxin B1 ranged from 72.97 to 195.17 μg/kg in all collected groundnut samples. Significant differences in levels of fumonisins were observed over time (p < 0.0001) but not among villages (p < 0.3209). Aflatoxin levels differed significantly among villages (p < 0.0491) and over time (p < 0.0001). The association between altitude and the level of aflatoxin contaminations was also significant. This study indicates that stored maize and groundnuts were more prone to mycotoxin contamination.
