Margin of Exposure-MOE.
Mean aflatoxins- Upper East = 32.84 µg/kg, Brong = 48.93 µg/kg, Ashanti = 62.37 µg/kg, Eastern = 53.14 µg/kg.
Central = 30.68 µg/kg, Western = 62.12 µg/kg.
Daily intake of maize for infants and toddlers were halved (0.5 × 0.107 kg/day).
Daily intake of 0.107 kg/day was used for children, adolescents and adults.
Benchmark Dose Lower limit = 400 ng aflatoxins/kg bw/day.
