Abstract
El trabajo de investigación se planteó para el estudio como objetivo principal determinar la relación existente entre coliformes, E. coli y Staphylococcus aureus en huevo cocido de codorniz con las condiciones sanitaria en la venta ambulatoria de los puestos en los mercados de Santa Anita. La muestra estuvo conformada por 16 PVAA (Puestos de venta ambulatorio de alimentos) de huevos cocidos de codorniz de los mercados del distrito de Santa Anita, la cual ha sido considerada basada en las limitaciones económicas para la presente investigación. La técnica fue Observacional (Check list) para las condiciones sanitarias y el recuento Microbiológico de Cuantificación de MO por PetrifilmTM. Los resultados demostraron que las condiciones sanitarias y la presencia de coliformes en los huevos cocidos de codorniz si están relacionados de manera significativa (51.6%), existe evidencia estadística suficiente para afirmar la importancia de los indicadores higiene del PVAA, Higiene alrededor del PVAA y el exclusivo uso que se da al expendio de alimentos. Existe relación significativa entre el número de colonias en Coliformes con Escherichia Coli, siendo esta relación positiva moderada de 0.541 (54,1%). Las prevalencias calculadas a partir de los PVAA que expenden huevos cocidos de codorniz relacionado con la presencia de Coliformes, Escherichia coli y de Staphylococcus aureus es de 56.2%, 31.2% y 100% respectivamente. En la prueba binomial, para la población considerando que va ser elevado si supera el punto de corte de 35% encontrándose que las UFC de coliformes y Staphylococcus aureus dieron positivo anulándose la hipótesis nula y aceptando la hipótesis alterna, a diferencia de E. coli que hay una presencia importante pero no es superior significativamente. El 50% no cumplen con los limites aceptable de coliformes, el 25% no cumplen con los límites de E. coli y el 100% no cumple con los límites de Staphylococcus aureus
The research work The objective of the study was to estimate the relationship between coliforms, E. coli and Staphylococcus aureus in cooked quail eggs with the sanitary conditions of ambulatory stalls in Santa Anita neighborhood markets. The sample consisted of 16 PVAA Food outlets) of boiled quail eggs from the markets of Santa Anita neighborhood, which has been considered based on the economic limitations for present research. The technique was Observational (Checklist) for sanitary conditions and the Microbiological count of MO quantification by PetrifilmTM. The results showed that the health conditions and the presence of coliforms in cooked quail eggs are significantly related (51.6%), there is enough statistical evidence to affirm the importance of PVAA hygiene, Hygiene around PVAA and Exclusive use For food expenditure There is a significant relationship between the number of coliforms in Coliforms and Escherichia coli, with this moderate positive relation being 0.541 (54.1%). Prevalences calculated from the PVAA spent cooked quail eggs refer to the presence of Coliforms, Escherichia coli and Staphylococcus aureus is 56.2%, 31.2% and 100% respectively. In the binomial of the test, for the population that considers that it is high and exceeds the cut-off point of 35%, finding that the CFU of coliforms and Staphylococcus aureus tested positive by canceling the null hypothesis and accepting the alternative hypothesis, a difference of E. Coli There is an important presence but it is not superior. 50% do not meet acceptable coliform limits, 25% do not meet the limits of E. coli and 100% do not meet the limits of Staphylococcus aureus
