Resumo: The work aimed to evaluate the microbiological quality of fresh eggs from different commercial establishments in the Metropolitan Region of São Luís, Maranhão State, Brazil. A total of 800 eggs obtained from public markets, retail supermarkets, wholesale supermarkets and grocery stores were analyzed. The samples of the internal content of the eggs were analyzed for the count of mesophilic aerobic heterotrophic bacteria (CBHAM), Staphylococcus spp., total yeasts and molds count, total and thermotolerant coliforms most probable number, and research for Salmonella spp., by conventional methods. Egg shell samples were evaluated particularly for Salmonella spp. The results for the aerobic mesophilic bacteria counts ranged from 102 to 104 CFU/mL, for Staphylococcus spp. count was 101 to 102 CFU/mL and yeast and mold count was 101 to 102 CFU/mL. The results showed that 12.5% ​​(5/40) of the samples was contaminated with total coliforms and 5% (2/40) with thermotolerant coliforms. Salmonella spp. was isolated in eggs samples, 12.5% ​​(5/40) of the internal egg and 17.5% (7/40) of the external eggs. It was concluded that fresh eggs marketed in the Metropolitan Region of São Luís presented a risk of spreading enteropathogens, regardless of the type of commercial establishment, and the commercial locations had favorable environmental conditions for microbial growth.

Se analizaron 800 huevos obtenidos de mercados públicos, supermercados minoristas, supermercados mayoristas y supermercados. Las muestras del contenido interno de los huevos se analizaron para el recuento de bacterias heterótrofas mesófilas aerobias (CBHAM), Staphylococcus spp., Mohos y levaduras, Número más probable (NMP / mL) de coliformes totales y termotolerantes, y Salmonella spp. por métodos convencionales. Las muestras de cáscara de huevo fueron evaluadas particularmente para Salmonella spp. Los resultados para el recuento de bacterias mesófilas aerobias oscilaron entre 102 y 104 UFC / ml, para Staphylococcus spp. era de 101 a 102 UFC / ml y el moho y la levadura era de 101 a 102 UFC / ml. Los resultados mostraron que el 12.5% ​​(5/40) de las muestras presentaron contaminación por coliformes totales y el 5% (2/40) con la presencia de coliformes termotolerantes. La bacteria Salmonella spp. se aisló en 12.5% ​​(5/40) del contenido interno y 17.5% (7/40) en el contenido externo de los huevos. Se concluyó que los huevos frescos vendidos en la Región Metropolitana de São Luís presentaban un riesgo de propagación de enteropatógenos, independientemente del tipo de establecimiento comercial, y las ubicaciones comerciales tenían condiciones ambientales favorables para el crecimiento microbiano.O trabalho objetivou avaliar a qualidade microbiológica de ovos in natura de diferentes estabelecimentos comerciais da Região Metropolitana de São Luís, MA. Foram analisados 800 ovos obtidos de mercados públicos, supermercados varejistas, supermercados atacadistas e mercearias. As amostras do conteúdo interno dos ovos foram analisadas quanto a contagem de bactérias heterotróficas aeróbias mesófilas (CBHAM), Staphylococcus spp., bolores e leveduras, Número Mais Provável (NMP/mL) de coliformes totais e termotolerantes, e pesquisa de Salmonella spp., por métodos convencionais. Amostras da casca dos ovos foram avaliados particularmente para pesquisa de Salmonella spp. Os resultados para a contagem de bactérias aeróbias mesófilas foi de 102 a 104 UFC/mL, de Staphylococcus spp. foi de 101 a 102 UFC/mL e de bolores e leveduras foi 101 a 102 UFC/mL. Os resultados mostraram que 12,5% (5/40) das amostras apresentaram contaminação para coliformes totais e 5% (2/40) com presença de coliformes termotolerantes. A bactéria Salmonella spp. foi isolada em 12,5% (5/40) do conteúdo interno e 17,5% (7/40) no conteúdo externo de ovos. Concluiu-se que os ovos in natura comercializados na Região Metropolitana de São Luís apresentaram risco de veiculação de enteropatógenos, independentemente do tipo de estabelecimento comercial, e os locais de comercialização apresentaram condições ambientais favoráveis ao crescimento microbiano.Research, Society and Development2020-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/617510.33448/rsd-v9i8.6175Research, Society and Development; Vol. 9 No. 8; e864986175Research, Society and Development; Vol. 9 Núm. 8; e864986175Research, Society and Development; v. 9 n. 8; e8649861752525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/6175/5955Copyright (c) 2020 Jaqueline da Silva Rumão, Daniela Aguiar Penha Brito, Christian Oliveira Reinehr, Alice Oliveira Conceição, Raynara Mendonça Frazãohttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRumão, Jaqueline da SilvaBrito, Daniela Aguiar PenhaReinehr, Christian OliveiraConceição, Alice OliveiraFrazão, Raynara Mendonça2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/6175Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:24.846666Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
