The incidence of <jats:italic>B. suis<\/jats:italic> brucellosis in dogs in Queensland (QLD) and New South Wales (NSW) has increased, likely due to hunting and consumption of feral pig meat. This study aimed to update estimates of <jats:italic>B. suis<\/jats:italic> seroprevalence and spatial distribution in feral pigs and assess the risk of transmission to dogs. Serology results from 686 feral pigs in QLD and NSW were analysed, with seroprevalence correlated to pig population density. Serology results from 3074 dogs in QLD and NSW were mapped to local government areas (LGAs) and compared with pig density. Raw feral pig meat sold for pet consumption was tested for <jats:italic>B. suis<\/jats:italic>. Thirty\u2010seven feral pigs were seropositive, with a survey adjusted true seroprevalence of 17% (95% confidence interval [CI] 12% to 22%) in QLD and 11% (95% CI 8% to 14%) in NSW. No positive spatial autocorrelation between positive and negative pigs was identified. Six hundred dogs from 26 QLD LGAs and 37 NSW LGAs were seropositive, showing a positive association with pig density. <jats:italic>Brucella suis<\/jats:italic> DNA was detected in commercially sold feral pig meat. This study found an increased prevalence and geographical expansion of infected pig populations potentially increasing the risk for <jats:italic>B. suis<\/jats:italic> transmission. The wide distribution and high level of detection in at\u2010risk dogs highlight the links to pig hunting. Investigating human and dog cases could help identify infected pig populations, enabling hunters to reduce contact with infected pigs in those areas.<\/jats:p>","DOI":"10.1111\/avj.13441","type":"journal-article","created":{"date-parts":[[2025,4,21]],"date-time":"2025-04-21T01:38:25Z","timestamp":1745199505000},"page":"379-387","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["<i>Brucella suis<\/i> in feral pigs in Australia: what is the risk?"],"prefix":"10.1111","volume":"103","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9201-3631","authenticated-orcid":false,"given":"CC","family":"Kneipp","sequence":"first","affiliation":[{"name":"Melbourne Veterinary School, Faculty of Science The University of Melbourne  Parkville Victoria 3010 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D","family":"Marshall","sequence":"additional","affiliation":[{"name":"Southern Queensland Landscapes  Toowoomba Queensland 4350 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ME","family":"Westman","sequence":"additional","affiliation":[{"name":"The New South Wales Animal and Plant Health Laboratories at the Elizabeth Macarthur Agricultural Institute, NSW Department Primary Industries  Menangle New South Wales 2568 Australia"},{"name":"Sydney School of Veterinary Science The University of Sydney  Sydney New South Wales 2006 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R","family":"Malik","sequence":"additional","affiliation":[{"name":"Centre for Veterinary Education University of Sydney  Sydney New South Wales 2006 Australia"},{"name":"School of Animal and Veterinary Sciences Charles Sturt University  Wagga Wagga New South Wales 2678 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"MA","family":"Stevenson","sequence":"additional","affiliation":[{"name":"Melbourne Veterinary School, Faculty of Science The University of Melbourne  Parkville Victoria 3010 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SM","family":"Mor","sequence":"additional","affiliation":[{"name":"Institute of Infection, Veterinary and Ecological Sciences The University of Liverpool  Liverpool L35RF UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"AK","family":"Wiethoelter","sequence":"additional","affiliation":[{"name":"Melbourne Veterinary School, Faculty of Science The University of Melbourne  Parkville Victoria 3010 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,4,20]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/9780470958209.ch22"},{"key":"e_1_2_9_3_1","first-page":"1","article-title":"Swine brucellosis: current perspectives","volume":"8","author":"Olsen S","year":"2017","journal-title":"Vet Med Res Rep"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3389\/fvets.2021.630960"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jiph.2025.102691"},{"key":"e_1_2_9_6_1","unstructured":"Queensland Government DAF.Brucellosis. 2018.
