ABSTRACT
Objective To investigate the level of metronidazole and prohibited drug residues in poultry meat and eggs in Hubei Province. Methods A total of 168 chicken and egg samples were collected from 13 prefecture level cities and autonomous prefectures of Hubei Province, Qianjiang City and Xiantao City. The residues of metronidazole, ribavirin, amantadine and rimantadine were determined by ultra performance liquid chromatography-mass spectrometry. Results Amantadine, ribavirin and rimantadine were not detected. The detection rate of metronidazole was 4.17% (7/168). There was significant difference in the detection rate of metronidazole in different years, but there was no trend of increase or decrease with the year; the difference of detection rate of banned drugs in different years was statistically significant, and had a trend of decreasing with the year. Conclusion The illegal use of metronidazole still exists in some areas of Hubei Province, which needs to be paid attention to by relevant departments.
