The aim of this study was to screen the contamination by ochratoxin A of mycotoxins in various medicinal herbs. We conducted a survey of ochratoxin A in medicinal herb on the retail market in Incheon in 2016. 116 medicinal herb samples were evaluated for the ochratoxin A contamination. They were analyzed for ochratoxin A using immunoaffinity column and high-performance liquid chromatography(HPLC)-fluorescence detection and the positive samples were confirmed using HPLCtandem mass spectrometry. Ochratoxin A was detected in 4 medicinal herb samples; the concentrations of ochratoxin A were containing between 20.11 and 372.90 μg/kg. This study shows that in general, this kind of commodity may be contaminated by mycotoxins. Also this contamination is not limited to only aflatoxin of mycotoxins.
