Enforcement of food safety regulations is necessary but insufficient to solve this problem. Aflatoxin contamination must be addressed at its root, during production and on-farm storage.
Research by International Food Policy Research Institute and others points to some solutions including education, incentivising farmers and removing the middleman. Educating farmers about how to prevent aflatoxin leads to better practices, which can also improve the quality of grain.
Kenya must also make aflatoxin prevention technologies affordable. Most farmers dry their maize on old woven sisal bags, through which mold spores can permeate. Upgrading to impermeable tarps or drying sheets is a highly cost-effective approach to aflatoxin control, but still costs farmers more than used bags. The new KEBS standard for tarps used in agriculture, which is expected to increase the availability of lower-cost tarps, is an important step forward.
