Abstract：Toexploredetectiontechnques forochratoxinB（OTB）andochratoxinC（OTC）infishmeat，aswellasprecisedetection techniques forochratoxin A（OTA），anew methodwasdeveloped forsimultaneous determinationofOTA，OTBandOTC incruciancarp using ultra-highperformanceliquidchromatogaphytandemmaspectrometry（UPLC-MS/MS），andthecontaminationof3toxinsin15 samplescolectedfromHangzhoumarketwasdetermined.Theresultsshowed thattheproposedmethodhdagodlinearrelatioshipin the mass fraction range of 0.1～50μg⋅kg-1 ，and average recovery rates of1， 5 μg⋅kg-1 and 25μg⋅kg-1 were 77.15%-107.59% through pretreatmentandoptimizationof detectionconditions.TheOTA detectionrateof 15commercially available samples was 20% ，and the highest detection value was 0.453μg⋅kg-1 .This method has good recovery rate and reproducibility，and is suitable for residual detection of ochratoxin in fish meat.
