This study was conducted to characterize the distribution of Salmonellaisolates in a poultry processing facility and to identify their antibiotic resistance profiles. Salmonella entericawas detected in 146 samples (66.7%), and 125 isolates were identified as SalmonellaHeidelberg (n= 123), SalmonellaAbony (n= 1), and SalmonellaO:4,5 (n= 1). SalmonellaHeidelberg isolates were subjected to XbaI macrorestriction analysis and pulsed-field gel electrophoresis. The 66 pulsotypes obtained were grouped into four major clusters, indicating cross-contamination and persistence of this serotype in the processing facility. Selected S. entericaisolates were characterized by their antibiotic resistance, and most (n= 122, 97.6%) were multidrug resistant. Resistance to third-generation cephalosporins ceftazidime (84 isolates, 67.2%) and cefotaxime and ceftriaxone (91 isolates, 72.8%) was particularly prevalent. Production of extended-spectrum β-lactamases (ESBL) was identified in 24 isolates (19.2%), and ESBL-producing isolates were resistant to at least eight antibiotics. This study revealed the high prevalence of SalmonellaHeidelberg in the poultry chain, providing insight into the ecology of this pathogen in this facility. The high prevalence of multidrug-resistant S. entericais a concern due to the potential consequences for public health.
