This study aimed to estimate the prevalence of Listeria monocytogenes (LM) in export-approved beef from Mato Grosso and to characterize the isolates in terms of molecular properties and antimicrobial resistance. From a total of 50 samples analyzed, Listeria sp. was isolated in 18 (36% prevalence). Listeria monocytogenes was confirmed in 6 (12% prevalence). Among the serotype groups assessed by multiplex PCR, serotype 4 (4b, 4d or 4e) was the most prevalent. Although antibiotic resistance was not an issue, two strains isolated from different plants showed high resistance to sodium hypochlorite. Overall, this scenario causes concern because it puts at risk not only the Brazilian customer, but also the population of countries that import beef from Mato Grosso.<\/jats:p>","DOI":"10.3390\/microorganisms8010018","type":"journal-article","created":{"date-parts":[[2019,12,20]],"date-time":"2019-12-20T09:50:33Z","timestamp":1576835433000},"page":"18","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Listeria monocytogenes in Export-approved Beef from Mato Grosso, Brazil: Prevalence, Molecular Characterization and Resistance to Antibiotics and Disinfectants"],"prefix":"10.3390","volume":"8","author":[{"given":"Larrayane A.C.","family":"Teixeira","sequence":"first","affiliation":[{"name":"College of Nutrition, Federal University of Mato Grosso, 78060-900 Cuiab\u00e1, MT, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernanda T.","family":"Carvalho","sequence":"additional","affiliation":[{"name":"College of Nutrition, Federal University of Mato Grosso, 78060-900 Cuiab\u00e1, MT, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deyse C.","family":"Vallim","sequence":"additional","affiliation":[{"name":"Laboratory of Bacterial Zoonoses, Oswaldo Cruz Institute, Oswaldo Cruz Foundation, 21040-360 Rio de Janeiro, RJ, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5297-573X","authenticated-orcid":false,"given":"Rodrigo C.L.","family":"Pereira","sequence":"additional","affiliation":[{"name":"Laboratory of Bacterial Zoonoses, Oswaldo Cruz Institute, Oswaldo Cruz Foundation, 21040-360 Rio de Janeiro, RJ, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adelino","family":"Cunha Neto","sequence":"additional","affiliation":[{"name":"College of Nutrition, Federal University of Mato Grosso, 78060-900 Cuiab\u00e1, MT, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2075-0565","authenticated-orcid":false,"given":"Bruno S.","family":"Vieira","sequence":"additional","affiliation":[{"name":"College of Animal Science, Federal Institute of Education, Science and Technology of Mato Grosso, 78580-000 Alta Floresta, MT, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo C.T.","family":"Carvalho","sequence":"additional","affiliation":[{"name":"College of Nutrition, Federal University of Mato Grosso, 78060-900 Cuiab\u00e1, MT, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2608-4324","authenticated-orcid":false,"given":"Eduardo E.S.","family":"Figueiredo","sequence":"additional","affiliation":[{"name":"College of Nutrition, Federal University of Mato Grosso, 78060-900 Cuiab\u00e1, MT, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.foodcont.2016.12.016","article-title":"A review of Listeria monocytogenes: An update on outbreaks, virulence, dose-response, ecology, and risk assessments","volume":"75","author":"Buchanan","year":"2017","journal-title":"Food Control"},{"key":"ref_2","first-page":"1","article-title":"What is new in listeriosis?","volume":"2014","year":"2014","journal-title":"Biomed Res.
