Aflatoxin Biocontrol Product Lowers Maize, Groundnut Contamination in Senegal


by A4NH | May 4, 2020

In Senegal, groundnut and maize are commonly contaminated with highly toxic, cancer-causing chemicals called aflatoxins, produced by fungi when they infect crops.

Recently, a team of plant pathologists from the International Institute of Tropical Agriculture (IITA), supported by A4NH, have developed an aflatoxin biocontrol product called Aflasafe® SN01, specifically designed for use in Senegal. Tests conducted in important crop production areas of Senegal for five years in more than 500 fields found the product to be highly efficient in reducing aflatoxin contamination in groundnut and maize.

The research, published in the February issue of Plant Disease, is a component of IITA's Africa-wide Alfasafe initiative, which develops and implements aflatoxin management strategies centered on the biocontrol technology. As of now, 14 Aflasafe products have been developed and registered for use in 10 African nations, with development in progress in an additional 10 countries.

Alejandro Ortega-Beltran received the 2020 William Boright Hewitt and Maybelle Ellen Ball Hewitt Award for his work on aflatoxin mitigation.


Aflatoxin exposure threatens food security throughout the developing world. Training and low-cost technology could help fight it, but further exploration of these on a larger scale is needed.
