Veterinary drug residues in domestic and imported foods of animal origin in the Republic of Korea.


PMID 25537072

Abstract

The Korean National Residue Programme comprises three different approaches for evaluating domestic and imported foods of animal origin: monitoring, surveillance/enforcement and an exploratory test programme. Monitoring and surveillance/enforcement testing programmes are routinely implemented by 17 Provincial Veterinary Services for domestic products and regional offices of the Animal and Plant Quarantine Agency (QIA) for imported products. The exploratory project conducted at QIA headquarters is designed to test substances that are not included in monitoring and enforcement testing programmes. Here, we carried out exploratory testing for determining the presence of 42 veterinary drugs that have no established Korean maximum residue limits and analysed their levels simultaneously, in a total of 3108 samples of domestic and imported animal-origin foods. Of the tested drugs, acetylsalicylic, paracetamol, clopidol, diclazuril, amprolium, toltrazuril and its metabolites (toltrazuril sulphone and toltrazuril sulphoxide) and phenylbutazone and its metabolites (oxyphenylbutazone) were detected.
