The deoxynivalenol content, presence of kernels infected by Fusarium spp. pathogens and the frequency of visually scabby kernels in wheat intended for human consumption were monitored in 2003-2005. About 1000 samples provided by growers from various regions of the Czech Republic were analysed each year. Immunochemical assay ELISA-based kits for the analysis of deoxynivalenol content were employed. In 2003, 2004 and 2005, deoxynivalenol was detected at the maximum levels of 5090 μg.kg−1, 18300 μg.kg−1 and 4437 μg.kg−1, respectively. Significant correlations were found between the deoxynivalenol content and percentage of kernels infected by Fusarium spp. pathogens, and percentage of visually scabby kernels. In all years under study, the relationship between the deoxynivalenol content and percentage of visually scabby kernels was closer than that between the deoxynivalenol content and percentage of kernels infected by Fusarium spp.
