At nine locations in 2004–2008, the incidence of deoxynivalenol (DON) in grains of wheat grown in Slovakia was studied, with a focus on samples that are important for production of cereal products. Altogether 184 wheat samples collected directly from growers were analysed for DON contents using the ELISA method. Year and location had a significant effect on DON concentration. There was a positive correlation between DON content and rainfall at given locations. The limit of 1.25 mg per kg imposed by the European Union (EU) for DON content was exceeded in 10.3% of the studied samples. The results show the tendency of increased toxin contamination of wheat grown in locations with higher rainfall during and after wheat flowering period and it also revealed the locations with frequent incidence of samples exceeding the EU limit in Slovakia.
