• Highly toxic metabolite produced by the ubiquitous Aspergillus flavus fungus
• The fungus resides in soil and crop debris, infects crops and produces the toxin in the field and in stores
Mobilization of private sector, selection of manufacturer and/or distributer partners, awareness raising
Test the market with investor, conduct large-scale demonstration and awareness raising
Work with investors to manufacture, distribute and build awareness, improve the product

• Managed by the National Irrigation Board (NIB)
• Highly productive area but aflatoxin-prone
• Maize frequently rejected as >50% strains in soil are highly toxic
Maize grown under center pivot in Galana-Kulaku, which is a part of 1 million acre Jubilee Food Security project of the Kenyan Govt.
• The entire crop of 3,500 acres treated with aflasafe
• 99% grain lots had <4 ppb aflatoxins
• Sufficient maize harvested to feed 492,000 people for 1 month in drought-stricken counties

AgResults Pilot
The Nigeria AflasafeTM Pilot focuses on incentivizing the adoption of AflasafeTM, by smallholder maize farmers.
AgResults is a USD $118 million multilateral initiative using pull mechanisms to
incentivize and reward high-impact agricultural innovations that promote global
food security, health, and nutrition and benefit smallholder farmers.
