摘要：

The aim of this study was to investigate ochratoxin A (OTA) and citrinin (CIT) co-occurrence in different unprocessed cereals (n=189) originating from Croatia during a three-year investigation period (2014-2016) using validated enzyme immunoassay (ELISA) methods. CIT and OTA were determined in 49% and 7% of samples, respectively. Significantly higher (p<0.05) overall mean concentrations were determined for CIT (66.8 +/- 76.0 mu g/kg) in comparison to OTA (5.2 +/- 1.1 mu g/kg). Based on the analysis of all investigated cereals, CIT was found about 15 times more frequently than OTA and in similarly (15-fold) higher concentrations, irrespective of the cultivation year. The results revealed a moderately positive correlation between OTA and CIT concentrations in maize (r(s)=0.44) and wheat (r(s)=0.59), whereas in barley and oat this correlation (p>0.01) was not significant.
