Exploring the Scope of Cost-Effective Aflatoxin Risk Reduction Strategies in Maize and Groundnut Value Chains to Improve Market Access and Health of the Poor in Africa Clare Narrod, IFPRI International Food Policy Research Institute Uniformed Services University of the Health Sciences International Center for the Improvement of Maize ACDI/VOCA/Kenya Maize Development Programand Wheat Kenya Agricultural Research Institute International Crops Research Institute for the Semi- Institut d’Economie Rurale Arid Tropics The Eastern Africa Grain Council University of Pittsburgh
Economic losses estimated to be large - dearth of systematic studies that empirically estimate economic losses (health, income) for all stakeholders along the value chain economic impact of interventions socio-economic factors affecting adoption Number of biological studies on control options; hasn’t been large scale adoption.

Mali: Kita, Kayes, and Koulikoro Districts ▪ 70 % of groundnuts produced in Western Mali ▪ Comprise all groundnut-producing agro- ecological zones Kenya: Nyanza Province (South West) ▪ Transect from Kisii to Homabay (high - low elevations) Upper East ▪ Transect from Embu to Mbeere (high - low lands) Lower East ▪ Transect that includes Machakos and Makueni Districts
Prevalence data collected from different AEZ from 2009-2011(Kenya) and 2009-2010 (Mali) at pre-harvest and in storage (15 to 30days interval), and in the markets (every month).

Laying the groundwork for coordinated policy action for aflatoxin control so as to improve market access and health of the poor in Africa.
Maize! They call you mahindi in Kiswahili, bembe in Kikamba How nice to mention. Oh Aflatoxin! Where did you come from? When the rain falls we harvest maize in plenty. When it doesn’t it dries out. Oh Aflatoxin! Where did you come from? Maize, we love to roast and like to boil. Even ugali, our staple food. Aflatoxin! Where did you come from? We enjoy maize very much. However, the devil, not the weevil, has stolen you Aflatoxin! Where did you come from? Aflatoxin they call you. You have stolen so many innocent lives Aflatoxin! Where did you come from?
