Food processing contaminants: Dietary exposure to 3-MCPD and glycidol and associated burden of disease for Italian consumers.

In this study we assessed Italian consumers' dietary exposure to 3-MCPD and glycidol followed by risk characterization, potential cancer risk and the associated burden of disease. Consumption data was retrieved from the most recent Italian Food Consumption Survey (2017-2020), while contamination data was obtained from the European Food Safety Authority. The level of risk due to exposure to 3-MCPD was negligible, below the tolerable daily intake (TDI), except for high consumption of infant formulas. For infants, the intake level was higher than the TDI (139-141% of TDI), indicating a potential health risk. Exposure to glycidol indicated a health concern for infants, toddlers, other children, and adolescents consuming infant formulas, plain cakes, chocolate spreads, processed cereals, biscuits, rusks, and cookies (margin of exposure (MOE) < 25,000). The risk of cancer due to exposure to glycidol was estimated and the overall health impact was quantified in Disability-Adjusted Life Years (DALYs). The risk of cancer due to chronic dietary exposure to glycidol was estimated at 0.08-0.52 cancer cases/year/100,000 individuals depending on the life stage and dietary habits in Italy. The burden of disease quantified in DALYs varied from 0.7 to 5.37 DALYs/year/100,000 individuals. It is crucial to continuously gather consumption and occurrence data for glycidol over time to track patterns, assess potential health risks, identify exposure sources, and develop effective countermeasures, as long-term exposure to chemical contaminants can lead to an increased risk for human health. This data is critical for protecting public health and reducing the likelihood of cancer and other health issues related to glycidol exposure.
