Ochratoxin A (OTA) ochratoxin B (OTB) and citrinin (CIT) in cereals were determinated simultaneously by liquid chromatography - electrospray ionization tandem mass spectrometry (LC/MS/MS). The quantification limits of OTA OTB and CIT in the samples were 0.07 0.03 and 0.07 μg/kg respectively. In 33 samples examined OTA was detected in 6 samples at levels of 0.2 - 1.8 μg/kg and CIT were detected in 2 samples at levels of 0.7 - 1.1μg/kg. One sample was co-contaminated with OTA and CIT. Contents of OTA detected in cereals were less than the regulation level of EU (5μg/kg).
