clean the operation area. Tableware cleaning places belong to the cleaning operation area. The main function of this area is to pick and clean food raw materials, and to store tableware, tools and containers that come into contact with direct food after cleaning and disinfection, and keep them clean. The hygiene requirements of the clean operation area are high, because the country has relevant hygiene standards, and catering companies that do not meet the standards may be required to close down for rectification. Therefore, food and beverage outlets usually employ cleaning staff to carry out cleaning work to ensure that they meet hygiene standards.
