Resumo: ObjectiveThe purpose of the research was to investigate the presence of Listeria, Salmonella and Klebsiella on samples of enteral diets and utensils, surfaces and equipments involved in food preparation in a hospital food service. MethodsFifty samples collected from utensils, surfaces and equipment used for food preparation in a hospital food service, and four samples collected from enteral diets were tested for bacteria of genera Listeria, Salmonella and Klebsiella. Typical colonies of bacteria of the genus Listeria from enteral diet were isolated in Oxford agar and contamination by L. monocytogenes was confirmed by immunoanalysis. ResultsL. monocytogenes, S. rissen and Klebsiella were isolated from enteral diet. For their relevance as agents of hospital infections, bacteria of the genus Klebsiella were evaluated. K. pneumoniae were found in equipment and utensil, and K. oxytoca were found in environment, equipment and enteral diet samples. L. monocytogenes showed resistance to cefoxitin and all Klebsiella were resistant to amoxacillin and ampicillin. S. rissen showed susceptibility to all 13 antibiotics tested. ConclusionThe study showed that 11% of the analyzed samples were contaminated with, at least, one of the investigated pathogens. Such results reiterate the need for awareness and knowledge of effective hygienic procedures in the hospital food manipulation areas, in order to ensure patients’ safety.

MétodosA contaminação de ambientes, utensílios e equipamentos de preparo de alimentos em serviço de alimentação hospitalar por Listeria monocytogenes, Salmonella sp. e Klebsiella sp. foi avaliada em 50 amostras coletadas pela técnica de swab. Quatro amostras de dietas enterais também foram analisadas. Colônias típicas de bactérias do gênero Listeria foram isoladas de dieta enteral em ágar Oxford e a identificação da espécie L. monocytogenes foi feita por testes bioquímicos e imunológicos. ResultadosA presença de Salmonella foi detectada em dieta enteral e identificada como S. rissen por sorologia. Pela relevância como agente causador de infecções hospitalares, bactérias do gênero Klebsiella foram pesquisadas e isoladas em ágar seletivo MacConkey-inositol-carbenicilina. K. pneumoniae foi encontrada em equipamento e utensílio e K. oxytoca em ambiente, equipamento e dieta enteral. Os isolados de L. monocytogenes apresentaram resistência apenas ao antibiótico cefoxitina e os do gênero Klebsiella foram resistentes a ampicilina e amoxilina. S. rissen foi sensível aos 13 antibióticos avaliados. ConclusãoA contaminação de 11% das amostras analisadas com pelo menos um dos patógenos, alerta para a necessidade de implantação de um rigoroso sistema de controle de qualidade nas áreas de manipulação dos alimentos, a fim de aumentar a segurança alimentar dos pacientes hospitalizados.Núcleo de Editoração – PUC-Campinas2023-08-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9194Brazilian Journal of Nutrition; Vol. 17 No. 3 (2004): Revista de NutriçãoRevista de Nutrição; Vol. 17 Núm. 3 (2004): Revista de NutriçãoRevista de Nutrição; v. 17 n. 3 (2004): Revista de Nutrição1678-9865reponame:Revista de Nutriçãoinstname:Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)instacron:PUC_CAMPporhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9194/6577Copyright (c) 2023 Uelinton Manoel PINTO, Rodrigo Rezende CARDOSO, Maria Cristina Dantas VANETTIhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess PINTO, Uelinton ManoelRezende CARDOSO, Rodrigo Dantas VANETTI, Maria Cristina 2023-08-11T19:40:12Zoai:ojs.periodicos.puc-campinas.edu.br:article/9194Revistahttp://www.scielo.br/rnPRIhttps://periodicos.puc-campinas.edu.br/nutricao/oai||sbi.submissionrn@puc-campinas.edu.br1678-98651415-5273opendoar:2023-08-11T19:40:12Revista de Nutrição - Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)false
