This report summarizes the key findings and the initial detailed statistical output from AflaSTOP’s Off-Farm Storage Device Testing. This research, now complete, investigated performance of hermetic (i.e. air-tight) storage devices in a controlled environment (e.g. small, enclosed, village / small town-based store rooms), compared to the control – the traditional, non-hermetic polypropylene (PP) bag used by the majority of small-scale farmers in East Africa. AflaSTOP tested the comparative effects on grain quality, mycotoxin content (e.g. aflatoxin and fumonisin), and insect infestation.
