In this study, we described a suitable prioritisation scheme on these exempted drugs and established fundamental rules for residue monitoring enforcement in Korea. The principles of exempted materials were established. Based on these established criteria, 75 materials with high priority were selected and grouped. Among these materials, we have decided that 25 substances required further review for monitoring. Important factors for determining the priority for monitoring, product factor during the recent 4 years, veterinary medicine factors, including applied symptoms and component conditions, animal factors, including applied animals, and toxicological factors including acceptable daily intake (ADI), establishment of residual quantity permitted (MRL) or withdrawal periods, various provisory clauses and so on were set. High priority substances were acethylsalicylic acid, bromhexine, chlorpheniramine, and acetaminophen. In addition, we surveyed and provided analysis on the above mentioned materials in this study. The derived results will be suggested to the Animal and Plant Quarantine Agency (QIA) for development of guidelines of policy direction and the effective targeting for their monitoring program.
