Title : Risk assessment of dietary exposure to deoxynivalenol in different age groups in Norway

Abstract:

The Norwegian Scientific Committee for Food Safety has assessed the risk for adverse effects of deoxynivalenol (DON) in different human age groups. DON is the most prevalent mycotoxin in Norwegian cereals, and DON is present in virtually all samples of cereal grain and cereal flour, bran, oat flakes and other cereal based food products. In years with low and high mean concentration of DON in the flour the exposure to DON was calculated for different age groups, based on occurrence and consumption data. The estimated mean and high (95-percentile) exposure to DON, respectively, were in the range of, or exceeded the TDI by up to 2 times in 1-year-old infants and 2-year-old children. In years with high mean DON concentration the high (95-percentile) exposure exceeded the TDI up to 3.5 times for 1-, 2-, 4- and 9-year old children. Although the TDI is not a threshold for toxicity, the assessment concluded that exceeding the TDI in infants and children is of health concern. The estimated dietary intakes of DON in adolescence and adult populations are equal to or below the TDI and not of health concern. Acute exposure to DON is not of concern in any of the age groups.
