Between May and August 2020, a multi\u2010jurisdictional outbreak of <jats:italic>Salmonella<\/jats:italic> Typhimurium (STm) infection due to zoonotic transmission was investigated in Australia. In total, 38 outbreak cases of STm with a median age of 5\u2009years were reported. Epidemiological investigation showed contact with live poultry to be a common risk factor with most cases recently purchasing one\u2010week old chicks from produce\/pet stores. Traceback investigation of cases identified 25 product\/pet stores of which 18 were linked to a single poultry breeder farm. On farm environmental sampling identified the same STm genotype as identified in cases. Whole genome sequencing of both environmental and human outbreak isolates found them to be highly related by phylogenetic analysis. This investigation describes the first documented widespread zoonotic salmonellosis outbreak in Australia attributed to backyard poultry exposure and identified potential risk factors and prevention and control measures for future outbreaks. Prevention of future outbreaks will require an integrated One Health approach involving the poultry industry, produce\/pet store owners, animal healthcare providers, public health and veterinary health agencies and the public.<\/jats:p>","DOI":"10.1111\/zph.12973","type":"journal-article","created":{"date-parts":[[2022,7,4]],"date-time":"2022-07-04T06:59:30Z","timestamp":1656917970000},"page":"835-842","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["A multi\u2010jurisdictional outbreak of <i>Salmonella<\/i> Typhimurium infections linked to backyard poultry\u2014Australia, 2020"],"prefix":"10.1111","volume":"69","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3360-9309","authenticated-orcid":false,"given":"Troy A.","family":"Laidlow","sequence":"first","affiliation":[{"name":"Communicable Diseases Branch Queensland Health  Brisbane Queensland Australia"},{"name":"National Centre for Epidemiology and Population Health, Research School of Population Health Australian National University  Canberra Australian Capital Territory Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Russell","family":"Stafford","sequence":"additional","affiliation":[{"name":"OzFoodNet, Communicable Diseases Branch Queensland Health  Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy V.","family":"Jennison","sequence":"additional","affiliation":[{"name":"Public Health Microbiology, Forensic and Scientific Services Queensland Health  Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Bell","sequence":"additional","affiliation":[{"name":"OzFoodNet, Communicable Diseases Branch Queensland Health  Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rikki","family":"Graham","sequence":"additional","affiliation":[{"name":"Public Health Microbiology, Forensic and Scientific Services Queensland Health  Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trudy","family":"Graham","sequence":"additional","affiliation":[{"name":"Public Health Microbiology, Forensic and Scientific Services Queensland Health  Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natasha","family":"Musgrave","sequence":"additional","affiliation":[{"name":"West Moreton Public Health Unit Queensland Health  Ipswich Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Myerson","sequence":"additional","affiliation":[{"name":"West Moreton Public Health Unit Queensland Health  Ipswich Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nina","family":"Kung","sequence":"additional","affiliation":[{"name":"Biosecurity Queensland, Department of Agriculture and Fisheries  Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allison","family":"Crook","sequence":"additional","affiliation":[{"name":"Biosecurity Queensland, Department of Agriculture and Fisheries  Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qinning","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Clinical Pathology and Medical Research, NSW Health Pathology  Westmead New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alun","family":"Richards","sequence":"additional","affiliation":[{"name":"Communicable Diseases Branch Queensland Health  Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2709-193X","authenticated-orcid":false,"given":"Stephen B.","family":"Lambert","sequence":"additional","affiliation":[{"name":"Communicable Diseases Branch Queensland Health  Brisbane Queensland Australia"},{"name":"National Centre for Epidemiology and Population Health, Research School of Population Health Australian National University  Canberra Australian Capital Territory Australia"},{"name":"National Centre for Immunisation Research and Surveillance  Westmead New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,7,3]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.onehlt.2016.08.002"},{"key":"e_1_2_9_3_1","unstructured":"Australian Eggs.
