Aflatoxin contamination levels were monitored in groundnut products derived from participatory on-farm demonstration plots, farm stores and markets in 21 districts in Northern Ghana in 2015 and 2016. Results clearly showed that improved production technology (variety + agronomic practises) significantly reduced aflatoxin contamination and increased kernel yield. Though no clear and consistent trend of varietal differences in aflatoxin contamination could be established from the studies over the two years across locations, NkatieSari showed the least mean contamination (2.74 ppb and 2.39 ppb) while SAMNUT 22 had the highest levels of contamination (7.51 ppb and 3.31 ppb) in 2015 and 2016 respectively. Most groundnut products sampled from households and markets, had aflatoxin levels higher than the EU acceptable limit of 4 ppb and this calls for more intensive sensitization of value chain actors, especially the processors, and rigorous monitoring of groundnut products to minimize the risks of human and livestock poisoning from aflatoxin contamination.
