This study was carried out to investigate the prevalence and antimicrobial resistance of Salmonella serotypes in duck farms of Jeollanam-do Province, South Korea. A total of 1112 samples (breeder ducks, 286; broiler ducks, 826) were collected from 196 duck farms (breeder duck farms, 25; broiler duck farms, 171) between January 2018 and November 2019. The total prevalence of Salmonella serotypes was 45.4% (89/196) in the duck farms, with no significant difference between prevalence in breeder and broiler duck farms (48% and 45%, respectively; P>0.05). The most prevalent serotype among the 127 Salmonella isolates was Salmonella Typhimurium (20.5%) followed by Salmonella Albany (17.3%), Salmonella Hadar (15.7%), and Salmonella Enteritidis (11.8%). Maximum resistance was observed against penicillin (78.74%), followed by tetracycline (68.50%), and kanamycin (65.35%). Of the 127 isolates, 117 (92.13%) were resistant to ≥3 antimicrobials and 2 to all 18 antimicrobials. Our results demonstrate the presence of Salmonella strains and their resistance to multiple antimicrobials, thus indicating a public health concern in South Korea. The emergence of Salmonella stains that are resistant to multiple drugs highlight the need for careful use of antimicrobials in duck farms.
