aThe average concentration of tetracycline in the total milk samples (252.4 μg/kg) was taken in to consideration in all cases
bBody weights for different age groups were derived from FAO/WHO guideline and relevant nutritional studies
cThe lowest amount of milk intake among Iranian adults and children were adapted from [24] as 33.6 ml/day and [25] as negligible, respectively
dThe average amount of milk intake among Iranian adults and children were adapted from [23] as 165 ml/day and [25] as 52 ml/day, respectively
eThe highest amount of milk intake among Iranian adults and children were obtained from [24] as 393 ml/day and [25] as 113 ml/day, respectively
fPer capita milk consumption data is considered as 246 g/d (the upper side of the rage announced by IDIS)
gEstimated daily intake (EDI):[Milk consumption X 252.41(mean concentration of TETs in milk)/1000]/body weight
