The process of measuring and assessing a facility's or an area's cleanliness and sanitation is known as hygiene monitoring. This is possible in a variety of venues, including public places like restaurants, hospitals, and schools. In order to make sure that the environment is secure and free from potential disease or infection sources, hygiene monitoring is necessary. Regular inspections, testing, and the use of appropriate cleaning and disinfection procedures are usually used to achieve this. The results of hygiene monitoring can be used to pinpoint problem areas and direct the use of corrective measures to keep a high standard of cleanliness.
