This study investigated the mycotoxins (aflatoxin B1, B2, G1, G2, fumonisin B1, B2, ochratoxin A and zearalenone) contained in edible and medicinal plants in Seoul Yangnyeong market during 2020?2021. We analyzed contamination of mycotoxins using LC-MS/MS and evaluated risk assessment. The method was validated by assessing matrix effects, linearity, limit of detection (LOD), limit of quantification(LOQ) and recovery. Matrix-matched standard calibration was used for calibration curves showed good linearity (r2>0.999). The LOD, LOQ and recovery were 0.01-0.23 mg/kg, 0.04-0.71 mg/kg and 75.5-117.9% respectively. Mycotoxins were detected in 22 of 171 samples; aflatoxin B1 (6.66 mg/kg), fumonisin (7.54-64.68 mg/kg), ochratoxin A (4.21-10.56 mg/kg) and zearalenone (7.31-60.76 mg/kg). In the risk assessment, the MOE (Margine of Exposure) of aflatoxin B1 and ochratoxin A were in the range of 1.48×103-2.36×105. No items exceeded 100% in %TDI (Tolerable Daily Intake) of fumonisin (B1+B2) and zearalenone.
