This study was undertaken to evaluate the contamination rate of Salmonella serotypes
and to determine their resistance profiling to six antibiotics from imported chicken
carcass surfaces at the food control unit in the Duhok city / Ministry of Health, Kurdistan
region of Iraq. in which the total 110 swabs were collected from April to June 2014. 21
samples out of 110 (19%) chickens were found to be contaminated with Salmonella and
belonging to 4 different serotypes. S. ohio 13 (61.9%) was the most frequent serotype
followed by S.newport 2 (9.5%), S.typhimurium 2 (9.5%), S.livingstone 1 (4.7%) and 3
(14.2%) isolates were non-typeable. 23.8% of the isolates were resistant to
ciprofloxacin, 100% to cephalothin, 85.7% to trimethoprim-sulfamethoxazole, 28.5% to
gentamycin, 76.1% ticarcillin-calvulanic acid while none of the isolates were resistant to
imipenem (100% were susceptible). All Salmonella serotypes were resistant to at least
one antibiotic and 16 (76.1%) have been resistant to three or more antibiotics. The results
of this study indicate that there are high contamination rate of Salmonella in chicken
carcasses with a high drug resistance profiling and require good strategies for controlling
the pathogen during slaughtering. In addition, the selection of antibiotics should be with
a more prudent
