Abstract
El objetivo de este estudio fue determinar la condición higiénica sanitaria de los centros de expendio de carne de pollo (CP) crudo de los mercados principales de la ciudad de Huánuco-Perú. Se muestrearon 50 establecimientos que expenden CP cruda. En cada uno de los locales se tomaron muestras de 200 g de carne, las cuales fueron procesadas en el LM-FMVZ UNHV. Para la detección de Escherichia coli, se empleó placas Petrifilm EC de acuerdo al método oficial y para Salmonella spp., el ensayo Salmonella Express System (SALX) en placas 3M Petrifilm. Paralelamente, para evaluar las condiciones higiénicas sanitarias de los establecimientos y de los responsables del expendio de carne, se aplicó un cuestionario de buenas prácticas de manipulación. Se observó que todas las muestras se encontraban contaminadas, con UFC/g PF de E. coli, en promedio 1988 UFC/g PF±3.74 de E. coli. Y en cuanto a Salmonella spp., todos los casos fueron positivos a la misma. Además, se demuestran condiciones higiénicas sanitarias deficientes y regulares de infraestructura. Por tanto, el expendio de CP cruda no cumple con las buenas prácticas de manipulación de alimentos. En los mercados de Huánuco, la CP expendida está considerada por la NTP no es apta para el consumo humano.
The objective of this study was to determine the sanitary hygienic condition of the raw chicken meat (CM) sales centers in the main markets of the city of Huánuco-Peru. 50 establishments that sell raw CM were sampled. Samples of 200 g of meat were taken in each of the premises, which were processed in the LM-FMVZ UNHV. For the detection of Escherichia coli, Petrifilm EC plates were used according to the official method and for Salmonella spp., The Salmonella Express System (SALX) assay on 3M Petrifilm plates. At the same time, to assess the sanitary and hygienic conditions of the establishments and those responsible for selling meat, a questionnaire on good handling practices was applied. It was observed that all the samples were contaminated, with CFU / g PF of E. coli, on average 1988 CFU / g PF±3.74 of E. coli, and as for Salmonella spp., all the cases were positive to it. In addition, poor and regular sanitary hygiene conditions of infrastructure are demonstrated. Therefore, the sale of raw CM does not comply with good food handling practices. In the Huánuco markets, the issued CM is considered by the NTP to be unfit for human consumption.
