Abstract

Pasteurizadora SantoDomingo S.A., is a national company with 55 years in the dairy industry that offers safe and high-quality products, thanks to its excellent quality control, which makes it easier to not only maintain customer satisfaction and protect the integrity of the brand, but also ensure long-term success in the competitive food market. This report shows the monitoring carried out in the company's microbiology laboratory, where microbiological and physicochemical analyzes are carried out, ranging from the receipt of raw materials to finished products. For example, in the case of raw milk, HRS control is carried out to prevent possible contamination of heat-resistant microorganisms in the finished UHT product, which could compromise compliance with commercial sterility, and in the case of drinking water supply, its microbiological quality is verified through of the membrane filtration method. In addition, hygiene conditions are evaluated in work environments, contact surfaces, by the swabbing method and among food handlers, since they represent a source of contamination if good hygiene and manufacturing practices are not followed during the production process. It was concluded that, from the microbiological and physicochemical analyzes carried out between March and June of the raw materials, finished products at Pasteurizadora Santo Domingo S.A., had a high percentage of acceptance. Furthermore, B. sporothermodurans was not detected in raw milk or finished products, reflecting good livestock practices. On the other hand, the microbiological quality of the drinking water supply reflects a continuous improvement during the evaluation period, while the environments, handlers and surfaces prove not to be a source of contamination during the production process.
