Evaluación microbiológica de la eficacia del desinfectante TEGO 51 empleado en el proceso de limpieza y desinfección de la Sacheteadora Effytec en Ginsberg Ecuador S.A.

Abstract

The microbiological evaluation of the Tego 51 disinfectant effectiveness used in the cleaning and disinfection process of the Sacheteadora Effytec was carried out at the Empresa Ginsberg Ecuador S.A., located in the city of Quito, Pichincha province. The contact plate and cotton swab bud method were used, in which the samples of the 8 critical control points were taken before using Tego 51 disinfectant. The Tego 51 disinfectant effectiveness to different concentrations (0.1, 0.5, and 1%) was evaluated. The microbiological equipment analysis was done using the taken samples with selective media culture for bacteria and fungi. Then the microorganisms were identified by Gram staining. Besides, the microorganisms were also identified morphologically. Cotton swab buds, contact plates, culture media, microscope and incubators were used. From the results, the used concentrations have shown to be capable of eliminating Staphylococcus aureus, Pseudomonas aeureginosa, Salmonella typhi, Aspergillus niger fungi and yeasts present in the Sacheteadora Effytec. Having evaluated Tego 51 disinfectant microbiologically, it is concluded that the most effective concentration capable of eliminating microorganisms present in the Sacheteadora Effytec is 1.0%, which is the concentration to be used, and it is registered in the standardized running procedure of the equipment cleaning and disinfection. It is recommended to train the staff in charge of cleaning and handling equipment before starting the cleaning and disinfection process. It is also necessary to keep the material used clean to guarantee reliable and safe results.
