ABSTRACT

Objective To know the residues of 13 veterinary drug residues in chicken and eggs foods in some areas in Xinjiang. Methods A total of 170 chicken and egg samples were randomly selected from supermarkets and farmers' markets in seven cities in Xinjiang. Eleven quinolone antibiotics, two tetracycline antibiotics, ribavirin and metronidazole were examined for veterinary drug residues using liquid chromatography tandem mass spectrometry (LC-MS/MS) . Results The overall detection rate of veterinary drug residues in eggs and chicken were 20%（18/90）and11.25%（9/80）. The overall over-standard rate were 18.89%（17/90）and 0（0/80）. Veterinary drug residues in chicken are heavier than eggs. Veterinary drugs were detected and over-standarded in all seven cities in Xinjiang monitored. Conclusion The veterinary drug contamination in chicken and eggs in Xinjiang is relatively serious. It is recommended to strengthen the standardization of production and supervision to ensure food safety.
