Occurrence of deoxynivalenol in maize and wheat in Serbia.

A total of 226 samples of maize and 59 of wheat from the 2004-2007 harvests were investigated for the presence and concentration of deoxynivalenol (DON). Samples of the 2004 harvest were analyzed after their storing for one year in barns, while those of the 2005-2007 harvest were taken directly off fields immediately after the harvest. The samples were analyzed by liquid chromatography on an ODS Hypersil column with DAD detector and ELISA methods.
