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
