  1. Margin of Exposure-MOE
  2. Mean aflatoxins- Hohoe = 21.15 µg/kg, Ho = 35.72 µg/kg, BD = 61.81 µg/kg, KT = 42.44 µg/kg
  3. Average Potency of aflatoxins = 0.0396
  4. Daily intake of maize for infants was halved (0.5 × 0.107 kg/day)
  5. Daily intake of 0.107 kg/day was used for children and adults
  6. (1 μg = 1000 ng)
  7. Total EDIs (Volta Region) = 0.797 + 1.156 + 1.98 + 1.353 = 5.286
