We assessed the presence of tetracyclines, quinolones, lincomycin, and streptomycin in ultra-high temperature (UHT) milk samples (n = 148) and pasteurized milk samples (n = 50) from China using an enzyme linked immunosorbent assay-based visualization microarray chip technique. The detection rates of tetracyclines, quinolones, lincomycin, and streptomycin were 4.7%, 3.3%, 2.7%, and 15.5%, respectively, in UHT milk and 16.0%, 4.0%, 2.0%, and 14.0%, respectively, in pasteurized milk. The maximum levels of tetracyclines, quinolones, lincomycin, and streptomycin in the sample were 9.06 μg kg−1, 4.06 μg kg−1, 7.66 μg kg−1, and 8.92 μg kg−1, respectively, which are lower than the maximum residue levels established in China, the Codex Alimentarius Commission, and the European Union, indicating the milk production/marketing system might be adequately controlling the antibiotic residue risk. However, considering the limited sample numbers, and relative high detection rates in spring and summer which might pose a health risk on population, control measures still need to be strictly enforced to keep these residues at safe levels. •148 UHT and 50 pasteurized milk samples were collected.•Milk samples were analysed for 4 Veterinary drugs by ELISA.•The highest detection rate of streptomycin was found in spring as 19%.•None of the veterinary drugs residues exceeded the MRLs set by China, CAC, and EU.
