Abstract:
This study aims to estimate dietary exposure to deoxynivalenol and fumonisins (FBs) of infants and toddlers in Turkey. A total of 75 processed cereal-based foods intended for infants and toddlers collected between July and October 2018, were analysed by high performance liquid chromatography (HPLC). DON was determined in 21.3% of samples with mean middle bound (MB) level of 28.4 μg/kg. Of the 16 quantifiable samples, only one showed values above 200 μg/kg. Fumonisin B₁ (FB₁) was detected at quantifiable levels only in three samples, while FB₂ was not found in any sample. Estimated mean MB chronic dietary exposures to DON in infants and toddlers were 0.161 and 0.118 μg/kg b.w. per day, while 95th percentile (P95) MB exposures to DON were estimated at 0.564 and 0.414 μg/kg b.w. per day, respectively. Mean MB dietary exposures to FBs for infants and toddlers, respectively, were 0.093 and 0.068 μg/kg b.w. per day; P95 exposure estimates were 0.079 and 0.058 μg/kg b.w. per day. Both for DON and FBs, mean and P95 exposures of infants and toddlers did not exceeded the threshold level of 1 μg/kg b.w. per day and are therefore not of health concern.
