Abstract
BACKGROUND: The present study was aimed to determine the residual amounts of chloramphenicol and enrofloxacin in broiler chickens muscle and liver sam-ples gathered from local markets of Tabriz City, northwestern Iran. METHODS: Ninety broiler chickens carcasses were collected from different local markets of Tabriz, during July/August 2013. Random samples of thigh and breast muscle and liver were gathered and kept at -80(°)C until analyzes. The samples were then assayed using enzyme-linked immunosorbent assay (ELISA) according to the protocol of each antibiotic kit. Data were statistically analyzed using the computer program SAS 9.1. RESULTS: Eighty two samples (91/1 %) contained residues of enrofloxacin, alt-hough mean (±SD)of enrofloxacin concentration was lower than the European Union maximum residue limits(MRLs) value (P<0.001). Moreover, 28 (31/1 %) had detectable concentrations of chloramphenicol while it was not defined any MRLs value for chloramphenicol because its using has been forbidden in food animals. CONCLUSION: The frequency of contamination with enrofloxacin was considerable for the analyzed samples. Furthermore, the existence of chloramphenicol in almost one third of samples seems to be a public health threat due to its illegal use in food animals including poultry.
