According to the findings, the mean AfB1 concentrations in soyabeans were 1.48g/kg, 0.14g/kg, 0.95g/kg, and 0.29g/kg in the states of Niger, Kogi, Plateau, and Nasarawa, respectively. In Niger, Kogi Plateau, and Nasarawa states, the mean levels of total aflatoxin in soyabeans were 6.63g/kg, 7.28g/kg, 12.28g/kg, and 5.65g/kg, respectively. The mean AfB1 cowpea concentrations were 0.52g/kg, 0.9g/kg, 0.88g/kg, and 0.77g/kg in the states of Niger, Kogi, Plateau, and Nasarawa, respectively. In the states of Niger, Kogi, Plateau, and Nasarawa, the mean total aflatoxin levels in cowpea were 5.62g/kg, 3.67g/kg, 5.76 g/kg, and 4.77 g/kg, respectively. The mean concentrations of AfB1 in bambara nuts were 0.61g/kg, 1.15g/kg, 1.09g/kg, and 1.41g/kg in the states of Niger, Kogi, Plateau, and Nasarawa, respectively. Mean Total Aflatoxin in bambara nuts was found to be 2.8g/kg, 6.06g/kg, 3.89g/kg, and 4.91g/kg in the respective states of Niger, Kogi, Plateau, and Nasarawa. While Total Aflatoxin exceeded the EU's permissible limit of 2.0g/kg in all grains across all States, the mean concentration of AfB1 did not.
