not every set of tableware with centralized disinfection is tested. By inquiring about the official website of the Health and Health Commission, it is known that not every piece of centralized disinfection four-piece tableware is tested, but it is a part of spot check, and the batches that fail to pass the test are put on file for investigation and rectification. Centralized disinfection refers to a series of activities in which tableware is recovered from catering service providers, cleaned, disinfected, packaged, stored and distributed. Therefore, centralized disinfection of four-piece tableware is not tested for every piece.
