Residues of veterinary drugs, pesticides, and environmental contaminants in domestic and imported foods of animal origin were monitored by the National Residue Program and inspection service in Korea in the past decade. In all, 134 substances were analyzed in the monitoring plan; 35 substances were examined in the surveillance and enforcement testing program, and 27 substances were investigated in exploratory projects. The overall trend of violation rates gradually decreased over the past decade. Pesticides were not found in any domestic samples of animal origin. The violation rates of chlortetracycline and oxytetracycline decreased, but quinolone and penicillin detections increased in Korea. Several kinds of residue violations of veterinary drugs, endosulfan, or dioxins were found in the imported products each year. In an example event in 2008, the Korea monitoring plan contributed globally to investigate the dioxin contamination from Chilean pork. Continuous monitoring based on internationally harmonized standards and methods provides the essential scientific basis to manage and ensure food safety.
