## Abstract

Salmonella enterica is a globally significant foodborne pathogen and a leading cause of gastrointestinal infections, with increasing concern over strains harboring antimicrobial resistance (AMR). This Data Note reports draft genome sequences of six S. enterica subsp. enterica isolates from fresh produce and agricultural environments in South Korea. The objective of this work was to provide genomic data on environmental Salmonella isolates, their serovar diversity, AMR gene profiling, and genetic attributes relevant to Salmonella surveillance and comparative genomics.

Draft genomes of six isolates consisted of 3 to 7 contigs with genome sizes ranging from 4.89 to 5.02 Mbp and GC content (%) between 51.89% and 52.24%. The isolates were identified as four serovars, including three S. Typhimurium, S. I 4,[5],12:i:-, S. Kentucky, and S. Montevideo, and five MLST types. Among them, three strains representing serovars including Typhimurium,I 4,[5],12:i:-, and Kentucky harbored acquired AMR genes, conferring resistance to aminoglycosides, aminopenicillins, diaminopyrimidines, sulfonamide, and tetracyclines. Our study highlights the genomic diversity and resistance potential of S. enterica isolates derived from preharvest agricultural environments, providing valuable resources for future comparative analyses and AMR surveillance efforts.
