Values with different superscripts along the same column are significantly different at P < 0.05. 1Probable Daily Intake (PDI) calculated by multiplying the aflatoxin concentration in groundnuts by consumption rates of groundnuts in Nigeria (52 g/person/day). 2Margin of exposure (MOE) calculated by dividing the benchmark dose lower limit (BMDL) for aflatoxins by AFB1 exposure. 3Population risk for primary liver cancer = exposure × average potency (0.04944). 4Mean of aflatoxin concentration.
