The purpose of this study was to compare the results of analysis of residual pesticides according to changes in the test method and principal items for residual pesticides and to evaluate potential risks to human health from contaminated agricultural products in Gwangju. GC-MS/MS and LC-MS/MS were performed on 12,817 samples collected from 2020 to 2022 and analysis for 311 (from Jan 2020 to Sept 2021) and 340 (from Oct 2021 to Dec 2022) pesticides was performed using multi-residue methods included in the Korean Food Code. The detection rates and violation rates that exceeded the maximum residue limit (MRL) showed a steady increase to 45.8% (1.0%) in 2020, 47.1% (1.4%) in 2021, and 54.2% (2.8%) in 2022. Following the revision of the test method and principal items, the detection rates and violation rates increased from 45.7% (1.2%) to 53.9% (2.6%). The contaminated agricultural products mainly included leafy vegetables and stalk and stem vegetables, and crown daisy was the most contaminated agricultural product over a period of three years. A continual increase in the rates of multi-residue pesticides detected has been observed over the past three years (51.2%, 51.6%, and 64.0%). Diazinon (10), Fluopyram (12), and Dinotefuran (14) were the pesticides detected most frequently by year. The results of risk assessment showed that the hazard index was below 100% for the contaminated agricultural products, which was confirmed as a safe level.
