In 2009–2010, 72 wine samples of Moravian and foreign origin were analysed for ochratoxin A contamination. A fast analytical method based on immunoaffinity column clean-up and followed by the ultra performance liquid chromatography coupled to fluorescence detection was used. LOD and LOQ values were 0.3 and 1.0ng/L. Ochratoxin A was detected in 11% of Moravian wines and the detected OTA level ranged from 1.2 to 71.2ng/L. In foreign wines, OTA level ranged from 1.6 to 227.0ng/L. The values of OTA in all studied samples were significantly below the maximum allowable limit, 2.0μg/kg, set by the European Union.
