In this research, the contamination with fusariotoxins and aflatoxins in cereal grains from the 2019 harvest was presented. A total number of 84 representative grain samples of wheat (32), barley (30) and maize (22) collected from different regions of Bulgaria wеre аnalyzed by Enzyme Linked Immunisorbent Assay (ELISA) method. The highest detected concentration of zearalenone was in maize grain samples (168 µg/kg), while in barley and wheat grain samples it was 156.78 µg/kg and 143 µg/kg, respectively. Deoxynivalenol was found in maize and barley grain samples with concentrations of 2860 µg/kg and 2290 µg/kg, respectively, while it was not detected in wheat grain samples. The highest concentration of fumonisins was in wheat samples 971 µg/kg followed by barley (738 µg/kg) and maize samples (520 µg/kg). The highest concentration of aflatoxins was 11.55 μg/kg in the barley grain sample, then 10.40 μg/kg in wheat and 9.90 μg/kg in maize grain samples. The concentrations of detected mycotoxins were bellow of maximum limits referenced by the European regulations.
