Clearing the road to higher quality groundnut production is being demonstrated in farmer participation plots that use improved varieties in combination with management practices to reduce crop contamination. It has been shown in certain regions of Mali that aflatoxin contamination in traders’ stocks can reach 120 parts per billion (ppb) and in groundnut markets up to 250 ppb, considerably higher than international standards for human consumption set at 4 ppb in the European Union and 20 ppb in the United States.
