a
Incidence number is represented by the number of positive samples/total sample in a category.
b
EU permissible level for total aflatoxins is 4 μg/kg and WHO advisory level is 10 μg/kg for foods intended for direct human consumption.
c
The first integer is the number and the integer in parentheses is the percentage of samples containing a specified level of aflatoxins.
