However, less attention has been given to its presence outside hospitals. In this cross-sectional, laboratory-based surveillance study, we investigated the occurrence of A. baumannii in ready-to-eat (RTE) foods sold at retail outlets in four cities of the Al-Qassim region, Saudi Arabia, during a single season. A total of 240 RTE food samples were analyzed using culture-based and molecular approaches for species confirmation, and antimicrobial susceptibility profiles were determined. A. baumannii was identified in 19 samples (7.9%), spanning several food categories. Most isolates showed resistance to multiple antimicrobial classes, and 16 met the criteria for multidrug resistance (MDR). Among the confirmed isolates, blaOXA-23-like was detected in 16 (84.2%), blaOXA-24\/40-like in 2 (10.5%), and blaOXA-58-like in 1 (5.3%). Resistance to fluoroquinolones, tetracyclines, and aminoglycosides was common, and OXA-type carbapenemase genes were detected in 16 isolates. These findings indicate that RTE foods can represent non-clinical environments in which MDR A. baumannii may be detected. Including food sources in antimicrobial resistance surveillance may therefore strengthen our understanding of the ecology of this pathogen within a One Health framework.<\/jats:p>","DOI":"10.3390\/pathogens15030261","type":"journal-article","created":{"date-parts":[[2026,3,2]],"date-time":"2026-03-02T14:06:56Z","timestamp":1772460416000},"page":"261","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Antimicrobial Resistance in Acinetobacter baumannii Isolated from Ready-to-Eat Foods in Saudi Arabia"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1699-6263","authenticated-orcid":false,"given":"Eman","family":"Marzouk","sequence":"first","affiliation":[{"name":"Department of Public Health, College of Applied Medical Sciences, Qassim University, P.O.
