Objective To investigate the residues characteristics of veterinary drug in Gallus gallus domesticus from Hubei Province and assess the dietary exposure risks. Methods The 34 types of veterinary drug residues were detected in 100 randomly collected samples of Gallus gallus domesticus from farms, agricultural markets, wholesale markets and slaughterhouses in Hubei Province in 2024 by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The dietary exposure risk assessment of detected veterinary drug residues was conducted using the veterinary drug residue risk ranking matrix of the United Kingdom Veterinary Drug Residue Committee and the index of food safety (IFS) method. Results The 12 kinds of veterinary drugs were detected in the samples, with a residue detection rate of 49%. Among these, 2 kinds of drugs were prohibited for use in food animals, and 1 kind of drug was approved for therapeutic use but prohibited from detection in animal-derived foods. The risk assessment revealed that the IFS values of all detected veterinary drugs were significantly less than 1, indicating a low dietary exposure risk from residues. Conclusion This suggests that the quality and safety of Gallus gallus domesticus in Hubei Province are satisfactory, with minimal health risks posed by residual veterinary drugs to humans.
