Swine are considered a reservoir for many Salmonella serotypes affecting humans; however, not all serotypes of concern in food animal products cause clinical signs of infection in swine. The objective of this study was to evaluate the presence and distribution of Salmonella spp. in finishing pigs at commercial farms across Kansas (USA). Five farms were selected and sampled when pigs weighed between 125 and 136 kg. Samples were collected and transported to the laboratory for processing following USDA-FSIS guidelines. Susceptibility and resistance profiles were also studied. Fifty-three percent (100\/186) of samples were culture positive for Enterobacteriaceae, and 14% (14\/100) were confirmed Salmonella positive by PCR with three of five farms having no PCR-positive samples. Salmonella serotype Braenderup was the most common serovar identified in environmental samples, while Salm. Infantis, Agona, and Montevideo were identified in fecal samples. Multidrug resistance patterns were only found in Farm 3, in fecal samples and in one floor sample. The observations reported in this study highlight areas of concern, such as locations prone to fecal contamination, to be considered when cleaning and sanitizing between groups of pigs to decrease presence of Salmonella spp. in farm environments.<\/jats:p>","DOI":"10.1093\/lambio\/ovad065","type":"journal-article","created":{"date-parts":[[2023,6,9]],"date-time":"2023-06-09T13:46:35Z","timestamp":1686318395000},"source":"Crossref","is-referenced-by-count":2,"title":["Investigation of the environmental presence of<i>Salmonella<\/i>spp. in finishing pigs at commercial swine farms in Kansas\u00a0(USA)"],"prefix":"10.1093","volume":"76","author":[{"given":"Olivia L","family":"Harrison","sequence":"first","affiliation":[{"name":"Department of Animal Sciences and Industry, College of Agriculture, Kansas State University , Manhattan, KS 66506 , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"KaWang","family":"Li","sequence":"additional","affiliation":[{"name":"Food Science Institute, College of Agriculture, Kansas State University , Manhattan, KS 66506 , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordan T","family":"Gebhardt","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Medicine\/Pathobiology, College of Veterinary Medicine, Kansas State University , Manhattan, KS 66506 , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chad B","family":"Paulk","sequence":"additional","affiliation":[{"name":"Department of Grain Science and Industry, College of Agriculture, Kansas State University , Manhattan, KS 66506 , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7268-4278","authenticated-orcid":false,"given":"Jason C","family":"Woodworth","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences and Industry, College of Agriculture, Kansas State University , Manhattan, KS 66506 , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan","family":"Rensing","sequence":"additional","affiliation":[{"name":"Department of Gender, Women, and Sexuality Studies, College of Arts and Sciences, Kansas State University , Manhattan, KS 66506 , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0671-8879","authenticated-orcid":false,"given":"Cassandra K","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences and Industry, College of Agriculture, Kansas State University , Manhattan, KS 66506 , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3329-3172","authenticated-orcid":false,"given":"Valentina","family":"Trinetta","sequence":"additional","affiliation":[{"name":"Food Science Institute, College of Agriculture, Kansas State University , Manhattan, KS 66506 , United States"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,6,5]]},"reference":[{"key":"2023062613150211100_bib1","doi-asserted-by":"crossref","first-page":"317","DOI":"10.1111\/1541-4337.12137","article-title":"Biosecurity measures to control Salmonella and other infectious agents in pig farms: a review","volume":"14","author":"Andres","year":"2015","journal-title":"Compr Rev Food Sci Food Saf"},{"key":"2023062613150211100_bib2","first-page":"19","article-title":"Evaluation of cleaning and disinfection procedures against Salmonella enterica at swine farms, transport and lairage facilities","volume-title":"Proceedings of the 9th International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork-Safe Pork","author":"Arg\u00fcello","year":"2011"},{"key":"2023062613150211100_bib3","doi-asserted-by":"crossref","first-page":"110","DOI":"10.1016\/j.mimet.2018.03.019","article-title":"A multiplex real-time PCR assay, based on invA and pagC genes, for the detection and quantification of Salmonella enterica from cattle lymph nodes","volume":"148","author":"Bai","year":"2018","journal-title":"J Microbiol Methods"},{"key":"2023062613150211100_bib4","doi-asserted-by":"crossref","first-page":"1861","DOI":"10.4315\/0362-028X-65.12.1861","article-title":"Distribution of Salmonella in swine production ecosystems","volume":"65","author":"Barber","year":"2002","journal-title":"J Food Prot"},{"key":"2023062613150211100_bib5","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1146\/annurev-animal-013120-043304","article-title":"Salmonella in Swine: prevalence, multidrug resistance, and vaccination strategies","volume":"10","author":"Bearson","year":"2022","journal-title":"Annu Rev Anim Biosci"},{"key":"2023062613150211100_bib6","doi-asserted-by":"crossref","first-page":"103","DOI":"10.1016\/j.prevetmed.2004.01.010","article-title":"Risk factors for Salmonella enterica subsp.
