          Abstract

          Fundamento: La triquinelosis continúa presentándose en nuestro medio de forma epidémica. La magnitud de cada epidemia depende del alcance del producto contaminado distribuido. En la primavera del año 2000 se investigó en la capital de Granada un episodio ocasionado por la venta de embutidos sin control sanitario. El objetivo de este trabajo es la descripción epidemiológica del brote causado por Trichinella britovi. Métodos: Estudio descriptivo del brote así como de las medidas de control. El alimento vehículo del parásito se investigó mediante encuesta epidemiológica. Resultados: Entre las semanas epidemiológicas 18-22 se declararon 38 casos. Los síntomas identificados con más frecuencia fueron fiebre, mialgias y edemas palpebrales. El 87% de las personas afectadas presentó eosinofilia. El 40% requirieron ingresos hospitalarios. Se encontró T. britovi en la longaniza. Conclusiones: Las epidemias de triquinelosis pueden superar los sistemas de inspección y control actuales, poniendo en riesgo la seguridad alimentaria. La difusión de la alerta sanitaria disminuye la demora diagnóstica. Proponemos la intensificación de la educación sanitaria y continuar con la implantación de programas de autocontrol en industrias y establecimientos, debidamente supervisados y evaluados. Se debe mantener un sistema de vigilancia epidemiológica sensible y de rápida actuación.

          Background: The magnitude of the epidemic depends upon the scope of the contaminated product distributed. In the spring of 2000, an episode caused by the sale of sausage products which had not undergone health inspection. The purpose of this study is to provide an epidemiological description of the outbreak caused by Trichinella britovi. Methods: Descriptive study of the control measures and those affected. The food products contaminated with this parasite was investigated by means of an epidemiological survey. Results: Thirty-eight (38) cases were reported throughout weeks 18-22 of the epidemic. The symptoms most often reported were fever, myalgia and palpebral edema. Eighty-seven percent (87%) of those affected tested positive for eosinophilia. Forty percent (40%) required hospitalization. Late diagnosis was curtailed once the alert had been broadcast. T. Britovi was found in the sausage product. Conclusions: Trichinellosis epidemics can occur despite the current inspection and control systems, placing food safety at risk. Broadcasting a health alert curtails late diagnosis. We propose intensifying health education and continuing the implementation of duly supervised and evaluated self-check programs in industries and establishments. A well-tuned, fast-reacting epidemiological monitoring system must be kept in place.

            Environmental and human influence on the ecology of Trichinella spiralis and Trichinella britovi in Western Europe.

            Surveys on Trichinella parasites in domestic and sylvatic animals collected in France, Italy, and in the Extremadura region of Spain showed that the distribution of Trichinella spiralis and Trichinella britovi is influenced by both environmental and human behaviour factors. In France, both Trichinella species are prevalent in the fox population from mountain areas and natural parks but are infrequent in wild boars (< 0.001%). In Italy, only T. britovi is present in sylvatic animals (foxes, wolves, and mustelids) living 500 m above sea level. This species is rare in wild boars (< 0.001%) in that area. Sylvatic trichinellosis is found in only 24% and 34% of French and Italian territory, respectively, while lowland areas may generally be considered Trichinella-free, because the domestic cycle is absent. The ecology of T. spiralis and T. britovi in the Extremadura shows a different picture from that observed in France and Italy because of the presence of both domestic and sylvatic cycles. The domestic cycle not only allows the maintenance of T. spiralis in the domestic environment, but it also has a great impact on the prevalence in wild boar populations. It does not influence the prevalence in vulpine populations. These data suggest (1) that domestic trichinellosis occurs only in rural areas of Western Europe in association with traditional swine-rearing practices, but not in industrialized pig farms; (2) that sylvatic trichinellosis occurs only in natural habitats which, in Western Europe, are widespread in mountain areas; (3) that the fox is the primary reservoir in the sylvatic cycle, where the parasite is maintained in a closed circuit and (4) that among sylvatic animals T. spiralis is present at lower altitude than is T. britovi.
