The objective of this study was to investigate the contamination of selected veterinary antibiotics in two swine farming systems in Phitsanulok province, Thailand. The samples including feeds, water supply, flush water, effluent, sediment, feces, and sludge were collected from typical and commercial swine farms. Soil samples were collected from agricultural field near the farms. The liquid samples were extracted with SPE, while the solid samples were extracted with ultrasonicassisted coupled with SPE. The target antibiotics were analyzed by RRLC-MS/MS. The results showed that 7 antibiotics were found in feeds, aqueous and suspended solids of water supply at maximum concentrations of 11,695.81 ± 16.38 μg/kg (lincomycin), 11,575.57 ± 0.81 ng/L (ciprofloxacin) and 461,942.13 ± 12.40 μg/kg (lincomycin), respectively. Six antibiotics were found in aqueous and suspended solids of flush water and fresh feces at maximum concentrations of 598.34 ± 17.27 ng/L (sulfamethazine), 62,918.29 ± 8.96 μg/kg (lincomycin) and 40,229.15 ± 19.71 μg/kg (lincomycin), respectively. Erythromycin was found in aqueous, suspended solids and sediment of effluent at maximum concentrations of 9,614.56 ± 1.46 ng/L, 154,500.08 ± 12.05 μg/kg and 71,123.61 ± 23.28 μg/kg, respectively. Six antibiotics were found in dried feces, dried sludge and agricultural field soil at maximum concentrations of 26,614.38 ± 21.47 μg/kg (lincomycin), 14,353.39 ± 1.55 μg/kg (ciprofloxacin) and 28,909.29 ± 2.73 μg/kg (trimethoprim). Veterinary antibiotics using in two swine farming systems resulted in the contamination of veterinary antibiotics in waste, treated waste and utilization applying to agricultural field. Consequently, to reducing contamination of antibiotics from swine farms in the environment should be paid attention.
