ABSTRACT
The aim of this study was to evaluate the level of antibiotic resistance of Salmonella strains isolated from scald, evisceration, and chiller water; non-eviscerated, eviscerated, and chilled carcasses; feathers; and feces collected in six chicken abattoirs. The 29 Salmonella strains belonged to S. Kentucky (34.5%); S. Enteritidis (20.8%); S. Anatum e S. Enterica subsp. Enterica 8,20:-:z6 (13.8%); S. Typhimurium (6.9%); S. Enterica subsp. Enterica 4,5, 12:i:-, S. Saintpaul and S. Tennessee (3.4%). All strains were submitted to antibiotic resistance test following Kirby-Bauer methodology, 25 (86.2%) strains were resistant to aztreonam and to ampicilin, 21 (72.4%) to tetracycline and 16 (55.2%) to amoxicilin/clavulanic acid and to sulfazotrim. Only one strain (3.45%) was gentamicin resistant. Two strains (6.9%) were resistant to amicacin. Resistance and susceptibility to all antibiotics tested was not detected.Salmonella strains were total or partially resistant to the antibiotics frequently used in aviculture. These note-worthy data draw attention to a danger of indiscriminate use of antibiotics in aviculture that may contribute for selection of resistant strains and this can cause foodborne infections in humans.
