Abstract
The aim of this work was to determine deoxynivalenol (DON) contamination in wheat-based food products in Argentina and to estimate DON exposure. The numbers of samples were determined according to a developed sampling plan. A total of 156 samples of different wheat products were randomly collected from food markets in Luján, Argentina, and analyzed for DON by gas chromatography. DON contamination ranged 7–271 ng g−1 for French bread, 5–149 ng g−1 for Vienna bread, 11–85 ng g−1 for crackers, 8–85 ng g−1 for pizza, and was 79 ng g−1 for noodles. The maximum contribution to DON intake was 7% of the PMTDI for French bread; the minimum was less than 1% for noodles. Assuming all groups had eaten all sampled foods and summing all groups’ intake contribution, the highest estimate DON exposure would only be <14% (for the 18–24-year old men group) of the DON daily dietary intake.
