| description | Pork meat is one of the most consumed foods at national level; however, inefficient ndling at any stage of the food chain can lead to contamination and microbial prevalence. Therefore, the objective of the present research work is to determine the microbiological quality of pork, sold in a market in Loja. The research had a cross-sectional observational design in which 24 samples of pork were collected from the spending sites located within a market in Loja. The presence of Escherichia coli, Salmonella spp. and Staphylococcus aureus through cultures and obtained by biochemical tests, additional colony-forming units per milliliter (ufc/ml) for mesophilic aerobes were counted according to the INEN 1338 regulations. The presence of Escherichia coli and Staphylococcus aureus was found in 8.33%, Salmonella spp. in 12.5% and mesophilic aerobes in values greater than 1.0 x 107 cfu/ml. In conclusion, the raw pork meat from the Loja market has bacteria and a count higher than what is allowed according to the food sanitation regulations in force in the country. It is recommended to carry out a traceability study to identify the origin of meat contamination. Key words: Microbiological cultures, Salmonella, Escherichia, Staphylococcus, Mesophilic aerobes. |

Key words: Microbiological cultures, Salmonella, Escherichia, Staphylococcus, Mesophilic aerobes.La carne de cerdo es uno de los alimentos de mayor consumo en la población nacional; sin embargo, el manejo ineficiente en cualquier fase de la cadena alimentaria puede generar contaminación y proliferación microbiana. Por lo tanto, el objetivo de este estudio fue determinar la calidad microbiológica en carne de cerdo expendida en un mercado de Loja. La investigación tuvo un diseño observacional de corte transversal en la que se recolectaron 24 muestras de carne de cerdo de los sitios de expendio ubicados dentro de un mercado de Loja. Se analizó la presencia de Escherichia coli, Salmonella spp. y Staphylococcus aureus a través de cultivos y se confirmó mediante pruebas bioquímicas, adicional se contabilizó las unidades formadoras de colonias por mililitro (ufc/ml) para Aerobios mesófilos de acuerdo a la normativa INEN 1338. Se encontró la presencia de Escherichia coli y Staphylococcus aureus en un 8,33%, Salmonella spp. en 12,5% y Aerobios mesófilos en valores mayores de 1,0 x 107 ufc/ml. En conclusión, la carne cruda de cerdo del mercado de Loja presenta bacterias y un recuento superior a lo permitido de acuerdo a la normativa de sanidad alimentaria vigente en el país. Se recomienda realizar un estudio de trazabilidad para identificar el origen de la contaminación de la carne. Palabras Clave: Cultivos microbiológicos, Salmonella, Escherichia, Staphylococcus, Aerobios mesófilos.LojaChávez Arrese, Stephanie Fernanda2023-05-04T17:55:56Z2023-05-04T17:55:56Z2023-05-04info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesis53 p.application/pdfhttps://dspace.unl.edu.ec/jspui/handle/123456789/26957spahttp://creativecommons.org/licenses/by-nc-sa/3.0/ec/info:eu-repo/semantics/openAccessreponame:Repositorio Universidad Nacional de Lojainstname:Universidad Nacional de Lojainstacron:UNL2025-05-02T13:30:28Zoai:dspace.unl.edu.ec:123456789/26957Institucionalhttps://dspace.unl.edu.ec/Universidad públicahttps://unl.edu.ec/https://dspace.unl.edu.ec/oaiEcuador***opendoar:02025-05-02T13:30:28falseInstitucionalhttps://dspace.unl.edu.ec/Universidad públicahttps://unl.edu.ec/https://dspace.unl.edu.ec/oai*Ecuador***opendoar:02025-05-02T13:30:28Repositorio Universidad Nacional de Loja - Universidad Nacional de Lojafalse |
