ABSTRACT
Introducción. Las enfermedades transmitidas por alimentos son un serio problema de salud pública y, el pollo, uno de los alimentos asociados con ellas. Objetivo. Determinar la distribución y frecuencia de brotes alimentarios asociados al consumo de pollo contaminado por Salmonella spp., Listeria monocytogenes y Staphylococus aureus, mediante una revisión sistemática de la literatura científica. Materiales y métodos. Se buscaron los estudios de brotes asociados a Salmonella spp., S. aureus y L. monocytogenes, en las bases de datos Medline, Pubmed, Science Direct,SciELO,Librería Cochrane (CCRT),Biblioteca Virtual en Salud (BVS), Highwire,HINARI y MedicLatina. Se obtuvieron los datos para el cálculo de odds ratios (OR) mediante la elaboración de tablas de contingencia en el programa RevMan5™. Resultados. Siete artículos cumplieron con los criterios de inclusión y no se encontraron reportes de L. monocytogenes. El OR global fue de 3,01 (IC95% 2,37-3,81), lo que se interpreta como una asociación significativa entre el consumo de pollo contaminado y la infección alimentaria. Se presentó heterogeneidad en los estudios incluidos (p=0,03), por lo que fue necesario un análisis por subgrupos de microorganismos; para el caso de Salmonella spp., el OR fue de 2,67 (IC95% 2,09-3,41). No se hizo análisis para S. aureus por reportarse un solo artículo. Conclusiones. Se encontró un OR de 2,61, lo que indica que hay una fuerte asociación entre el consumo de pollo y la adquisición de salmonelosis. El principal factor de riesgo para adquirir salmonelosis es el consumo de pollo de asadero en los restaurantes.
Introduction. Food borne diseases are a serious public health problem. Poultry are often associated with these outbreaks. Objective. A systematic review of the literature is provided concerning the distribution and frequency of food borne outbreaks associated with consumption of chicken contaminated with Salmonella spp., Listeria monocytogenes and Staphylococcus aureus. Materials and methods. The search for studies of outbreaks associated with Salmonella, S. aureus and L. monocytogenes was conducted in Medline, Pubmed, Science Direct, Scielo, Cochrane Library (CCRT), Virtual Health Library (VHL), Highwire, HINARI and MedicLatina. Data were obtained for the calculation of odds ratio (OR) by preparing contingency tables using the RevMan5 program. Results. Seven articles met the inclusion criteria; however, no reports of L. monocytogenes were obtained. The overall OR was 3.01 (95% CI: 2.37, 3.81); this was interpreted as a significant association between the consumption of contaminated chicken and food poisoning. In the included studies heterogeneity (p= 0.03) was presented, so it took a subgroup analysis of microorganisms, in the case of Salmonella OR was 2.67 (95% CI: 2.09 -3.41). No analysis was made for S. aureus reported a single article. Conclusions. The OR indicated a strong association between chicken consumption and acquisition of salmonellosis. The main risk factor for acquiring salmonellosis is the consumption of chicken from grill restaurants.

O uso do método rápido de detecçäo de Salmonella por motilidade no meio semi-sólido de Rappaport-Vassiliadis modificado foi avaliado, em comparaçäo com o método clássico de detecçäo de Salmonella. Quatro das 12 cepas avaliadas em cultura pura apresentaram falso resultado negativo (S. infantis, S derby, S. typhimurium e S. newport), enquanto 8 cepas foram detectadas pelo método rápido. Em cultura pura, a detecçäo de Salmonella foi possível quando as populaçöes atingiram níveis de 10(5) - 10(7) células/ml e a taxa de falso negativos observada em alimentos foi de 5 por cento

A total of 60 lates niloticus fish-Kishre El-Bayad-were bacteriologically examined for detection of salmonella organisms. Salmonella typhimurium could be isolated from the surface of 4 fish samples only [0.66%]. The public health significance of the isolated organisms was discussed
