ABSTRACT
The objective of this study was to evaluate the dispersion dynamics and antimicrobial resistance profiles of Salmonella in the processing of Tambatinga (Colossoma macropomum x Piaractus brachypomus). Thirty fish were monitored during four processing stages (reception, first wash, evisceration, and prepackage area) in a fish slaughterhouse. One hundred and twenty fish surface samples were collected and tested through bacteriological analysis, PCR, serotyping, and antimicrobial resistance profile (disk-diffusion). Of these samples, 7.5% (9/120) were positive for Salmonella, with 0.83% being observed in the pre-packaging phase, indicating a low occurrence at this stage. All the analyzed stages were positive for Salmonella, with the prevalent serovars being Ndolo, Mbandaka, Typhimurium, Rough, and O16. All strains were sensitive to various antimicrobials. Improvements in microbiological control during all processing stages should be implemented to ensure a Salmonella-free product.
