Determination of deoxynivalenol in cereal-based foods and estimation of dietary exposure.

Deoxynivalenol (DON) is a trichothecene mycotoxin. DON contamination in agricultural food staples such as wheat, barley, and maize due to Fusarium colonization is an increasing problem. In order to provide risk managers with better guidance for regulatory measures, the concentration of DON in cereal-based foods (n = 689), collected from six cities between June 2005 and August 2008, was determined.
