Abstract :
Background: The present study was aimed to determine the residual amounts
of chloramphenicol and enrofloxacin in broiler chickens muscle and liver samples
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, although
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.
