Resumo: | High levels of microbial contamination, commonly found in animal origin foods and food processing environments, are able to hinder the growth of pathogens in these products and interfere in the results of laboratory analyses for detection of these pathogens. With the aim of verifying the possible interference of the autochthonous microbiota encountered in meat and meat products and processing plants over the presence of Listeria spp., 443 samples, collected from 11 meat retail establishments, were submitted to microbiological analysis to determine the levels of mesophilic aerobes, total coliforms and Escherichia coli and the presence of Listeria spp., according to the methodology proposed by the USDA. The results did not show evident interference of the autochthonous microbiota over Listeria spp., once the genus was detected even in the meat, meat products and environmental samples with high levels of contamination by mesophilic aerobes and coliforms. |

Com o objetivo de verificar as possíveis interferências da microbiota autóctone encontrada na carne, produtos cárneos e plantas de processamento sobre a presença de Listeria spp., 443 amostras, coletadas em 11 estabelecimentos processadores, foram submetidas a análises microbiológicas para determinação dos níveis de contaminação por aeróbios mesófilos, coliformes totais e Escherichia coli e para verificação da presença de Listeria spp., de acordo com a metodologia proposta pelo USDA. Os resultados obtidos não mostraram uma interferência evidente da microbiota autóctone sobre Listeria spp., uma vez que esse gênero foi detectado mesmo nas amostras de carne e produtos cárneos e amostras ambientais e de superfície de equipamentos que apresentaram altos níveis de contaminação por aeróbios mesófilos e coliformes.Em processamentoSociedade Brasileira de MicrobiologiaListeria spp. associated to different levels of autochthonous microbiota in meat, meat products and processing plantsListeria spp. associado a diferentes níveis da microbiota autóctone de carne, produtos cárneos e plantas de processamentoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlemeatListeria spp.autochthonous microbiotacarneListeria spp.microbiota autóctoneinfo:eu-repo/semantics/openAccessengreponame:Repositório Institucional da UnBinstname:Universidade de Brasília (UnB)instacron:UNBORIGINALa05v38n4.pdfapplication/pdf592918http://repositorio2.unb.br/jspui/bitstream/10482/27101/1/a05v38n4.pdfc93335e947f383625610770d0bd6d1fbMD51open access10482/271012023-10-11 14:11:33.05open accessoai:repositorio2.unb.br:10482/27101Biblioteca Digital de Teses e DissertaçõesPUBhttps://repositorio.unb.br/oai/requestopendoar:2023-10-11T17:11:33Repositório Institucional da UnB - Universidade de Brasília (UnB)false |
