This study was done to investigate the pesticide residues of ginseng cultivated in Jeollabuk-do from 2009 to 2016. The total number of samples were 1,942 cases in the production stage and 189 compounds for pesticides. These were analyzed by multi-residue Analytical method using GC-ECD/NPD and LC-UVD/FLD. There were 680 cases detected the pesticide residues. Among the 1,942 samples, residual pesticides were detected in 680 samples. The ratio of detection was 25~46% and the average was 36%. 31 pesticides were detected in ginseng, and Tolclofos-methyl was the most frequently detected in 525, followed by Azoxystrobin 80, Thifluzamide 43, Boscalid 22, Difenoconazole 17 and Cypermethrin 13. In addition, 10 components that do not have safety guideline for ginseng, including Chlorpyrifos, Diazinon, and Procymidone, were detected. The rate of two or more compounds detectded was 17%. The total number of samples detected over MRLs was 40 cases which was 2.1% on average. And Tolclofos-methyl was detected 15 times and the concentrations were in the range of 0.36 to 3.55 mg/kg. Followed by Boscalid 5 times, 0.44-2.05 mg/kg, Cypermethrin 5 times, 0.19 to 6.14 mg/kg, and Azoxystrobin 5 times, and 0.20 to 0.43 mg/kg. The risk index for Tolclofos-methy was 1.7 × 10?4% and the detected over MRLs was 1.8 × 10?1%. Although the result of the risk assessment is low, safety management should be continuously carried out considering the steady increase in the pesticide ratio of detection.
