The aim of this study was to investigate the presence Salmonella enterica in by‑products (feathers, spleen, cecum, and crop) from broiler slaughterhouses as well determine antimicrobial resistance profile identified serovars. Forty‑four lots broilers nine located central‑west region Brazil were evaluated. Samples feathers, crop collected a pool total 1,232 samples evalueted. These processed for conventional bacterial isolation subjected biochemical serological tests identify serovars susceptibility test, where different antimycotics investigated. 7.1% (87/1,232) all evaluated samples, mostly feathers (12.3%) spleen (8.1%). most frequent Schwarzengrund (29.9%), Agona (25.4%), Mbandaka (12.7%) Anatum Nine showed at least one antimicrobial, especially Mbandaka, Infantis Typhimurium. Amoxicillin tetracycline not effective inhibiting five four serovars, respectively.
