    Feeding infants with maize can expose them to fumonisin mycotoxins. We assessed fumonisin exposure from complementary foods in rural Tanzania and determined strategies to reduce the exposure. We conducted a cross-sectional study in four villages of Tarakea division, Northern Tanzania. We used a repeat 24-hour dietary recall to collect data of maize consumption as complementary food for 254 infants aged 6-8 months. Fumonisin concentrations in the maize were also estimated. Fumonisin exposure was assessed using @risk analysis software. With the software, several maximum fumonisin contamination and maize consumption patterns were combined in order to determine effective strategies for minimizing fumonisin exposure. Of the infants, 89% consumed maize at amounts up to 158 g/person/day (mean; 43 g/person/day +/- 28). The maize was contaminated with fumonisins at levels up to 3201 microg kg(-1) . Risk of fumonisin intake above the provisional maximum tolerable daily limit of 2 microg kg(-1) body weight was 15% (95% confidence interval; 10-19). The risk was minimized when the maximum contamination was set at 150 microg kg(-1) . The risk was also minimized when the maximum consumption was set at 20 g/child/day while keeping the maximum contamination at the European Union (EU) maximum tolerated limit (MTL) of 1000 microg kg(-1) . Considering the economical and technological limitations of adopting good agricultural practices in rural Tanzania, it is practically difficult to reduce contamination in maize to 150 microg kg(-1) . We suggest adoption of the EU MTL of 1000 microg kg(-1) for fumonisins in maize and reduction, by replacement with another cereal, of the maize component in complementary foods to a maximum intake of 20 g/child/day.
