Outline
To analyze the residual status of 7 kinds of antibiotic veterinary drugs in commercially available animal-derived prepared dishes collected from 7 districts of Beijing in 2024, and assess the dietary exposure risks induced by veterinary drug residues via consumption of animal-derived prepared dishes.
A total of 160 samples of commercially available animal-derived prepared dishes were collected from 7 districts in Beijing, and the residual concentrations of 7 kinds of antibiotic veterinary drugs were determined. The mean values, maximum values, P50, P75 and P97.5 were calculated. Combined with the recommended intakes of livestock, poultry and aquatic products for different age groups specified in the Dietary guidelines for Chinese residents (2022) and the consumption data of livestock, poultry and aquatic products among Beijing residents, the point estimation method was adopted to conduct dietary exposure risk assessment.
Lomefloxacin and norfloxacin were not detected. Enrofloxacin, ciprofloxacin, ofloxacin, pefloxacin and doxycycline were detected at varying levels, with detection rates of 18.8%, 5.6%, 3.2%, 0.6% and 31.2%, respectively. The dietary exposure levels of enrofloxacin+ciprofloxacin, doxycycline and ofloxacin via animal-derived prepared dishes for populations of different age groups ranged from 0.0007 to 0.3312 μg/(kg·BW). The risk quotients calculated based on mean and maximum residues were between 0.0001 and 0.0534, and the hazard indices ranged from 0.0017 to 0.0051.
The health risks from intake of the 7 kinds of antibiotic veterinary drugs through animal-derived prepared dishes are low for populations of different age groups in Beijing.
