Tesis doctoral de Elena Carrasco Jimenez <\/strong><\/h2>\n

En la presente tesis doctoral se analiza el riesgo alimentario de listeriosis a trav\u00e9s del consumo de ensaladas de iv gamma. Listeria monocytogenes en un microorganismo pat\u00f3geno prevalente en una amplia gama de alimentos, entre ellos, los vegetales, tanto crudos como tratados en forma de ensalada de iv gamma o listas para consumo. en primer lugar, desde un enfoque tradicional de la seguridad alimentaria, se investig\u00f3 la aplicaci\u00f3n de criterios microbiol\u00f3gicos seg\u00fan el reglamento (ce) n\u00c2\u00ba 2073\/2005 en ensaladas de endivias de iv gama, empleando modelos predictivos. con ello, se demostr\u00f3 que un modelo primario ajustado a datos de crecimiento del pat\u00f3geno en el alimento permite la no superaci\u00f3n de 100 ufc\/g del pat\u00f3geno a lo largo de la vida comercial en un 21% de las condiciones consideradas, por lo que, pese a que le producto presente cierta preValencia de contaminaci\u00f3n, se puede comercializar siempre y cuando son supere este l\u00edmite de 100 ufc\/g. desde un enfoque novedoso de la seguridad alimentaria, el de an\u00e1lisis de riesgos seg\u00fan el reglamento (ce) n\u00c2\u00ba 178\/2002, se abord\u00f3 el estudio de l.Monocytogenes en una ensalada de lechuga de iv gama t\u00edpica; adem\u00e1s, se recab\u00f3 informaci\u00f3n acerca del consumo de ensaladas de iv gama y de la temperatura den los frigor\u00edficos dom\u00e9sticos, para finalizar con una evaluaci\u00f3n y gesti\u00f3n del riesgo de listeriosis a trav\u00e9s del consumo de estas ensaladas, dentro del contexto del an\u00e1lisis de riesgo. el estudio del crecimiento de l.Monocytogenes a 5 y 13\u00c2\u00bac en ensalada de lechuga de iv gama, y con una composici\u00f3n inicial de gases de 4,65%-6,2% co2, 2,1-4,3% o2 y balance de n2, present\u00f3 una tasa de crecimiento menor y una mayor densidad de poblaci\u00f3n que las halladas por otros autores en ensaladas sin inyecci\u00f3n inicial de gases. la mayor densidad m\u00e1xima pudo deberse al efecto \u00abjameson\u00bb. la fase de adaptaci\u00f3n fue mayor que la encontrada por otro autores a 5\u00c2\u00bac, posiblemente debido al efecto inhibidor de la<\/p>\n
