BROTE EPIDÉMICO POR TRICHINELLA BRITOVI EN GRANADA DURANTE LA PRIMAVERA DEL 2000 Begoña López Hernández M. Teresa Gea Velázquez de Castro M. Dolores Galicia García Jose Carlos Sabonet Salud Zoonosis Triquinelosis Brote epidémico Fundamento: La triquinelosis continúa presentándose ennuestro medio de forma epidémica. La magnitud de cada epidemiadepende del alcance del producto contaminado distribuido.En la primavera del año 2000 se investigó en la capital de Granadaun episodio ocasionado por la venta de embutidos sin controlsanitario. El objetivo de este trabajo es la descripción epidemiológicadel brote causado por Trichinella britovi.Métodos: Estudio descriptivo del brote así como de las medidasde control. El alimento vehículo del parásito se investigómediante encuesta epidemiológica.Resultados: Entre las semanas epidemiológicas 18-22 se declararon38 casos. Los síntomas identificados con más frecuenciafueron fiebre, mialgias y edemas palpebrales. El 87% de laspersonas afectadas presentó eosinofilia. El 40% requirieron ingresoshospitalarios. Se encontró T. britovi en la longaniza.Conclusiones: Las epidemias de triquinelosis pueden superarlos sistemas de inspección y control actuales, poniendo enriesgo la seguridad alimentaria. La difusión de la alerta sanitariadisminuye la demora diagnóstica. Proponemos la intensificaciónde la educación sanitaria y continuar con la implantaciónde programas de autocontrol en industrias y establecimientos,debidamente supervisados y evaluados. Se debemantener un sistema de vigilancia epidemiológica sensible y derápida actuación. 2001 artículo científico 1135-5727 https://www.redalyc.org/articulo.oa?id=17075507 es http://www.redalyc.org/revista.oa?id=170 Revista Española de Salud Pública application/pdf Ministerio de Sanidad Revista Española de Salud Pública (España) Num.5 Vol.75
