Abstract
Groundnut is of undeniable nutritional importance in the Sahel countries, where few crops have as many nutritional or financial advantages. However, it is susceptible to aflatoxin, a highly toxic substance produced by the fungus Aspergillus flavus. Infection is favoured by water stress towards the end of the cycle, and African regions regularly hit by drought, such as Senegal, Niger and Mali, are thus at particular risk. This brings serious health risks, such as liver cancer, as local populations may consume large quantities of contaminated products. Moreover, with the tightening of European health regulations, the export value of groundnut has dropped considerably, which means a financial risk for the countries concerned. To reverse this trend, it is vital to prevent contamination in the field and at every stage of marketing.
