Prevalence and Antimicrobial Susceptibility of Salmonella in Rendered Animal Products Used in Poultry Feed in Turkey.

The increased prevalence of Salmonella contamination in poultry has gained considerable scientific attention during last decades. In this study, a total of 500 samples of rendered animal products (meat meal, meat-bone meal, blood meal, chicken meal and feather meal) were obtained from several feed factories and rendering plants in Turkey and these samples were analyzed for Salmonella spp., Salmonella Enteritidis and Salmonella Typhimurium status. According to the results, 13,11 and 8 samples obtained from feed factories were determined positive for Salmonella spp., Salmonella Enteritidis and Salmonella Typhimurium respectively. However, all samples obtained form rendering plants were negative. Antibiotic susceptibility profiles of isolates confirmed as positive were determined by using 17 different antibiotics. It was determined that Salmonella spp. and Salmonella Enteritidis serovars were resistant to amikacin, cephazolin and erythromycin, sensitive to amoxicillin, chloramphenicol, flumoquin, phosphomycin, kanamycin, oxytetracycline, spiramycin, streptomycin, tetracycline, tobramycine and vancomycin and moderate sensitive to gentamicin, linkomycin and rifampicin.
