EDI: estimated daily intake; CR: consumption rate; MoE: margin of exposure; AFT: total aflatoxins (sum of AFB1, AFB2, AFG1, and AFG2). Other abbreviations are as defined in Table 1. * Mean concentrations of determinations by food item collected from the four districts. Note: the average wights (±SD) of the surveyed females and males were 55.24 ± 5.90 and 68.12 ± 4.44 kg, respectively.
