Actualmente el Perú cuenta con el 1% de la población de ovinos en el mundo que equivalen a 9 341 721 (INEI, 2012). La carne de ovino por lo general es usada para autoconsumo, siendo uno de sus principales problemas, la poca aceptación cuando proviene de animales viejos, debido al fuerte y desagradable olor, producto de la acumulación del ácido 4-etiloctanoico en la carne (Sutherland y Ames, 1996). La utilidad de la aplicación de tecnologías novedosas con la finalidad de enmascarar este fuerte olor y diversificar la comercialización de la carne, se incrementa cuando se utilizan insumos que se producen en la misma región como la quinua (Chenopodium quinoa), que tiene gran valor nutritivo y la harina de cebada (Hordeum vulgare). Por lo anteriormente indicado, el objetivo principal de este trabajo fue desarrollar un cabanossi de carne de ovino con inclusión de quinua y harina de ce...

The aim of this study was to determine the presence ofListeria monocytogenes in pig carcasses in Lima, Peru. Samples were collected from the the surface of 88 carcasses in a slaughterhouse. Samples were enriched with BLEB medium and PALCAM broth. The pathogen was identified using the in situ hybridization molecular technique. The 13.9 ± 6.1% of carcasses were positive to L. monocytogenes, possibly due to deficiencies in the application and control of good manufacturing practices and standard sanitary operations in the slaughterhouse.
