Monitoring slaughtering stages and checking contamination points are crucial for the production of safe food. In this context, the aim of this study was to verify contamination by STEC strains, to determine the contamination points and evaluate the resistance profile to 12 antimicrobials used in both veterinary and human medicine. A total of 80 samples were obtained from eight collection points (pen floor, rectum, hide, carcass swabs and esophagus, diaphragm, masseter, and retail beef tissue samples). The isolates were collected by dilution plating on MacConkey agar with sorbitol, cefixime, and tellurite and analyzed by multiplex polymerase chain reaction for virulence genes. Serotyping of non-O157 was performed, and testing for 12 antibiotics by disk diffusion was carried out. A total of 18 STEC strains were isolated, presenting different virulence profiles. Contamination by STEC was observed in the rectum (5\/18), carcass surface (5\/18), hide (3\/18), diaphragm (2\/18), retail beef (2\/18), and masseter muscle (1\/18). Pen floor swabs and esophagus tissues showed no STEC contamination. Moreover, three strains were identified as O26 and three as O113:H21 strains, which have been linked to HUS and HC outbreak cases in Brazil. All STEC isolates were susceptible to all evaluated antimicrobials, except streptomycin. The presence of STEC strains is a direct risk to the consumer, especially when isolated from retail beef, and contamination can occur during different slaughter stages. However, antimicrobial resistance profiles did not identify multidrug-resistant strains, limiting potential antimicrobial resistance transmission to other pathogens.\n                  <\/jats:p>","DOI":"10.1089\/fpd.2018.2431","type":"journal-article","created":{"date-parts":[[2018,7,23]],"date-time":"2018-07-23T13:29:21Z","timestamp":1532352561000},"page":"653-659","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":22,"title":["<i>Escherichia coli<\/i>\n                    O26 and O113:H21 on Carcasses and Beef from a Slaughterhouse Located in Mato Grosso, Brazil"],"prefix":"10.1177","volume":"15","author":[{"given":"Elis Caroline Celestina dos","family":"Santos","sequence":"first","affiliation":[{"name":"Universidade Federal de Mato Grosso","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vinicius Silva","family":"Castro","sequence":"additional","affiliation":[{"name":"Instituto de Qu\u00edmica","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adelino","family":"Cunha-Neto","sequence":"additional","affiliation":[{"name":"Universidade Federal de Mato Grosso","place":["Brazil"]},{"name":"Universidade Federal Fluminense","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis Fernando dos","family":"Santos","sequence":"additional","affiliation":[{"name":"Instituto Adolf Lutz","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deyse Christina","family":"Vallim","sequence":"additional","affiliation":[{"name":"Instituto Oswaldo Cruz","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo de Castro","family":"Lisb\u00f4a","sequence":"additional","affiliation":[{"name":"Instituto Oswaldo Cruz","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ricardo C\u00e9sar Tavares","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Universidade Federal de Mato Grosso","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos Adam Conte","family":"Junior","sequence":"additional","affiliation":[{"name":"Instituto de Qu\u00edmica","place":["Brazil"]},{"name":"Universidade Federal Fluminense","place":["Brazil"]},{"name":"Instituto Oswaldo Cruz","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduardo Eust\u00e1quio de Souza","family":"Figueiredo","sequence":"additional","affiliation":[{"name":"Universidade Federal de Mato Grosso","place":["Brazil"]},{"name":"Universidade Federal de Mato Grosso","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,10,10]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13756-015-0100-5"},{"key":"e_1_3_3_3_1","doi-asserted-by":"publisher","DOI":"10.1086\/314715"},{"key":"e_1_3_3_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s13213-014-0961-5"},{"key":"e_1_3_3_5_1","doi-asserted-by":"publisher","DOI":"10.5433\/1679-0359.2014v35n4p1947"},{"key":"e_1_3_3_6_1","doi-asserted-by":"publisher","DOI":"10.1089\/fpd.2011.1082"},{"key":"e_1_3_3_7_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0189613"},{"key":"e_1_3_3_8_1","doi-asserted-by":"publisher","DOI":"10.1590\/S1517-83822007000300032"},{"key":"e_1_3_3_9_1","unstructured":"BRASIL..
