A survey of aflatoxin B1 and ochratoxin A was conducted on dried red pepper and red pepper powder. Total number of 193 samples were collected from local markets in Incheon. The presence of aflatoxin B1 and ochratoxin A was determined by high performance liquid chromatography (HPLC) with fluorescence detector using immunoaffinity column clean-up. The recovery rate of aflatoxin B1 and ochratoxin A were more than 80% and the limits of quantification were 0.13 μg/kg for aflatoxin B1 and 0.30 μg/kg for ochratoxin A. Aflatoxin B1 was detected in 33 samples (17.1%) with a range of 0.14~9.67 μg/kg and ochratoxin A was detected in 40 samples (20.7%) with a range of 0.31~3.31 μg/kg. These results show that the occurrence of aflatoxin B1 and ochratoxin A in dried red pepper and red pepper powder tested in this study is low compared with the standard in Korea Food Code (10 μg/kg as aflatoxin B1 and 7 μg/kg as ochratoxin A).
