Objective To investigate the levels of veterinary drug residues in chicken and eggs in chicken production bases in Liangshan Prefecture, and evaluate the dietary exposure risk. Methods There were 353 samples of chicken and eggs collected from 17 cities in Liangshan in 2022, then the residues of quinolones and quinoline were detected and analyzed by liquid chromatography-mass spectrometry, and the exposure risk was assessed by point estimate method. Results A total of 221 pieces of chicken were sampled in 2022, among 8 types of veterinary drugs were tested with the detection rate of 25.79%, and the unqualified rate was 1.81%. Among 132 eggs, only enrofloxacin residue was detected, the detection rate was 1.52%, the unqualified rate was 1.52%. The point estimate method was used to assess the dietary risk of veterinary drug residues, and its hazard quotient was lower than 1, indicating that the veterinary drug residues have a lower risk to human health. Conclusion Veterinary drug residues can be detected in some samples of chicken and eggs in Liangshan in 2022, and the risk residues to human health is low, but the health risks of caused by some undetectable veterinary drugs cannot be ignored.
