Salmonella enterica diversity and antimicrobial resistance profile in broiler slaughterhouse by-products.

The aim of this study was to investigate the presence of Salmonella enterica in by‑products (feathers, spleen, cecum, and crop) from broiler slaughterhouses as well as to determine the antimicrobial resistance profile of the identified serovars. Forty‑four lots of broilers in nine slaughterhouses located in the central‑west region of Brazil were evaluated. Samples of spleen, feathers, cecum, and crop were collected in a pool and a total of 1,232 samples were evalueted.
