Abstract:
ObjectiveTo evaluate the proficiency and consistency of domestic and foreign testing institutions in the field of veterinary drug residue detection in food， and to promote international cooperation and mutual recognition of testing results among these institutions. MethodsA robust statistical analysis was conducted on the testing results of 20 laboratories in eight countries and regions across North America， Europe， and Asia. The laboratories’ testing capabilities were evaluated using Z-score comparison. ResultsAmong the 20 participating laboratories， 18 achieved satisfactory results， resulting in a satisfaction rate of 90%， while 2 laboratories （10%） failed to meet the requirements. The satisfaction rate of domestic laboratories （100%） was higher than that of foreign laboratories （81.8%）. ConclusionDomestic laboratories perform better than overseas laboratories in determining veterinary drug residues in food. To enhance testing capabilities， these overseas laboratories with unsatisfactory evaluation results should strengthen their daily quality control and ensure traceability of original records.
