The project will compare business models for sustainably managing food safety risk through adoption of an aflatoxin bio-control agent, Aflasafe, and rapid testing for aflatoxin contamination. The business models will be assessed through a randomized controlled trial, in which farmers are linked to high value output markets demanding aflatoxin-safe maize. The study site is a known aflatoxin hotspot in Kenya, which is also a significant and reliable maize production area. Primary outcomes to be assessed are adoption of Aflasafe and test kits by farmers, prices received by farmers for their maize, and the safety of maize consumed by participating farmers and sold to millers.
