Resumo: The aim of this study was to evaluate the hygienic-sanitary quality of lamb meat sold in the city of Uruguaiana, Rio Grande do Sul (RS) by counting the indicator microorganisms and detecting pathogens such as Salmonella spp. and Listeria monocytogenes. Thirty-nine lamb meat samples were collected from 10 commercial establishments in Uruguaiana. The samples were subjected to counts of aerobic mesophilic microorganisms and enterobacteria, and to the detection of Salmonella spp. and L. monocytogenes, all following standard methods. The average counts of mesophilic microorganisms and enterobacteria were 6.08 log CFU/g (minimum 4.07 and max 6.87) and 4.73 log CFU/g (minimum 0 and max 5.88), respectively. For pathogens, L. monocytogenes was isolated from five samples (12.82%), with three samples in the same location. Only two samples (5.13%) were positive for Salmonella spp. The results demonstrated unsatisfactory hygienic-sanitary conditions because high counts of pathogens such as Salmonella spp. and L. monocytogenes. The counts of enterobacteria showed poor hygiene conditions during the various stages of production. The results also indicated fecal contamination, as Salmonella spp. and L. monocytogenes are present in the intestinal tract of both humans and animals. The high count of mesophilic microorganisms obtained could be owing to contaminated raw material or unsatisfactory processing, including unsanitary conditions and the inappropriate use of binomial time/temperature during storage.

Trinta e nove amostras de carne de cordeiro foram coletadas em 10 estabelecimentos comerciais em Uruguaiana. As amostras foram submetidas a contagens de microrganismos aeróbios mesofilos e enterobactérias e à detecção de Salmonella spp. e L. monocytogenes, todas seguindo metodologias padrão. As contagens médias de microrganismos mesófilos e enterobactérias foram 6,08 log UFC/g (mínimo 4,07 e máximo 6,87) e 4,73 log UFC/g (mínimo 0 e máximo 5,88), respectivamente. Para os patógenos, L. monocytogenes foi isolado de cinco amostras (12,82%), com três amostras no mesmo local. Apenas duas (5,13%) foram positivas para Salmonella spp. Os resultados demonstraram condições higiênicosanitárias insatisfatórias, baseado nas altas contagens de patógenos como Salmonella spp. e L. monocytogenes. As contagens de enterobactérias indicaram más condições de higiene durante as várias etapas de produção. Os resultados também indicaram contaminação fecal, uma vez que Salmonella spp. e L. monocytogenes estão presentes no trato intestinal de humanos e animais. A alta contagem de microrganismos mesófilos obtidos pode ser devida a matéria-prima contaminada ou processamento insatisfatório, incluindo condições insalubres e uso inadequado do binômio tempo/temperatura durante o armazenamentoSociedade de Medicina Veterinária do Estado do Rio de Janeiro.2021-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdftext/xmlhttps://rbmv.org/BJVM/article/view/114410.29374/2527-2179.bjvm114420Brazilian Journal of Veterinary Medicine; Vol. 43 No. 1 (2021); e114420Revista Brasileira de Medicina Veterinária; v. 43 n. 1 (2021); e1144202527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://rbmv.org/BJVM/article/view/1144/1064https://rbmv.org/BJVM/article/view/1144/1232Copyright (c) 2021 Vanessa Mendonça Soares, Aryele Nunes da Cruz Encide Sampaio, Emanoelli Aparecida Rodrigues dos Santos, Leonardo Ereno Tadielo, Juliano Gonçalves Pereirahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMendonça Soares, Vanessa Nunes da Cruz Encide Sampaio, Aryele Rodrigues dos Santos, Emanoelli Aparecida Ereno Tadielo, Leonardo Gonçalves Pereira, Juliano 2022-06-27T14:13:46Zoai:ojs.rbmv.org:article/1144Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2022-06-27T14:13:46Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false
