The genus\n Salmonella<\/jats:italic>\n includes two species (\n Salmonella bongori<\/jats:italic>\n and\n S. enterica<\/jats:italic>\n ) and six subspecies (\n enterica<\/jats:italic>\n I,\n salamae<\/jats:italic>\n II,\n arizonae<\/jats:italic>\n IIIa,\n diarizonae<\/jats:italic>\n IIIb,\n houtenae<\/jats:italic>\n IV, and\n indica<\/jats:italic>\n VI), each of which contains multiple serotypes associated with animal and human infections. The aim of the study was to evaluate the presence of\n Salmonella<\/jats:italic>\n spp. in carcasses of food-producing animals and foods in southern Italy and the serovar distribution among different sources. From 2011 to 2021, a total of 12,246 foods and 982 samples from animal carcasses were collected and analyzed. The overall percentage of positive samples was 5.84% (\n N<\/jats:italic>\n \u2009=\u2009773) and a significant increase in prevalence was observed by comparing the years 2011\u20132015 (257, 3.27%) and 2016\u20132021 (516, 9.61%;\n p<\/jats:italic>\n &lt; 0.05). The highest percentage of positive food samples was observed in \u201cMeat and Meat Products\u201d (\n N<\/jats:italic>\n \u2009=\u2009327\/2,438, 13.41%) followed by \u201cFish and fishery products\u201d (\n N<\/jats:italic>\n \u2009=\u2009115\/1,915, 6.01%). In carcasses, the highest percentage of positive samples was reported from broilers (\n N<\/jats:italic>\n \u2009=\u200942\/81, 51.85%) followed by buffalo (\n N\u2009=<\/jats:italic>\n 50\/101, 49.50%) and pork (\n N\u2009=<\/jats:italic>\n 140\/380, 36.84%). After typing, the isolates were assigned to the species\n S. enterica<\/jats:italic>\n and to the subspecies:\n enterica<\/jats:italic>\n (\n N\u2009=<\/jats:italic>\n 760, 98.32%),\n diarizonae<\/jats:italic>\n (\n N\u2009=<\/jats:italic>\n 8, 1.03%),\n salamae<\/jats:italic>\n (\n N\u2009=<\/jats:italic>\n 3, 0.39%) and\n houtenae<\/jats:italic>\n (\n N\u2009=<\/jats:italic>\n 2, 0.26%).\n S.<\/jats:italic>\n Infantis was the most frequently detected (\n N\u2009=<\/jats:italic>\n 177, 24.76%), followed by\n S.<\/jats:italic>\n Derby (\n N\u2009=<\/jats:italic>\n 77, 10.77%), monophasic\n S<\/jats:italic>\n . Typhimurium (\n N\u2009=<\/jats:italic>\n 63, 8.81%),\n S<\/jats:italic>\n . Typhimurium (\n N\u2009=<\/jats:italic>\n 54, 7.55%), and\n S.<\/jats:italic>\n Rissen (\n N\u2009=<\/jats:italic>\n 47, 6.57%). By comparing the sampling period 2011\u20132015 with that of 2016\u20132021, an increase in the prevalence of\n S.<\/jats:italic>\n Infantis and monophasic\n S<\/jats:italic>\n . Typhimurium and a decrease of\n S<\/jats:italic>\n . Typhimurium were recorded (\n p<\/jats:italic>\n &lt; 0.05). Thus, present data suggest that, despite the implementation of national and European control strategies to protect against\n Salmonella<\/jats:italic>\n , the prevalence of this pathogen in southern Italy is still increasing and a change of national control programs to protect against\n Salmonella<\/jats:italic>\n are necessary.\n <\/jats:p>","DOI":"10.3389\/fmicb.2022.1005035","type":"journal-article","created":{"date-parts":[[2022,10,6]],"date-time":"2022-10-06T09:13:02Z","timestamp":1665047582000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":31,"title":["Occurrence and distribution of Salmonella serovars in carcasses and foods in southern Italy: Eleven-year monitoring (2011\u20132021)"],"prefix":"10.3389","volume":"13","author":[{"given":"Maria Francesca","family":"Peruzy","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yolande Th\u00e9r\u00e8se Rose","family":"Proroga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Federico","family":"Capuano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Mancusi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angela Michela Immacolata","family":"Montone","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Cristiano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Balestrieri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicoletta","family":"Murru","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,10,6]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"44","DOI":"10.1016\/j.ijfoodmicro.2012.11.013","article-title":"Sero-and genotyping of Salmonella in slaughter pigs, from farm to cutting plant, with a focus on the slaughter process","volume":"161","author":"Arguello","year":"2013","journal-title":"Int.
