Antibiotic residues contained in poultry eggs pose threat to human health. However, the classes and concentrations of antibiotics egg southwestern China is unknown due insufficient monitoring research. A total 513 samples were collected from supermarkets farm markets Kunming city 2020 levels 7 analyzed using ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method. The linear correlation coefficients above 0.990 for all tested. limits detection quantification 0.002 0.010 μg/g 0.007 0.033 μg/g, respectively. average recoveries analytes 80.00 128.01%, with relative standard deviations less than 13.97%. 93 (18.13%) tested positive antibiotics, highest concentration being 2.48 μg/g. range ofloxacin, danofloxacin, difloxacin, sulfadimethoxine, sulfamonomethoxine, sulfamethoxypyridazine, sulfamethoxazole was 0.01 0.37 0.06 0.48 0.05 0.29 0.03 0.16 1.00 0.37, 0.07 Sulfamonomethoxine detected hen level at Sulfamethoxazole both duck quail eggs, 1.87 antibiotic residue pheasant which Sulfamethoxypyridazine identified 30 rate 5.85%, sulfadimethoxine 3 lowest 0.58%. We observed that targeted eggs. also found there free-range not low. These findings suggest continual essential China.
