1, the public health certificate is mainly for those who directly provide services to the public, such as hotel waiters, shopping mall staff, beauty salons and so on. Holders of such health certificates need to have regular health checks to ensure that infectious diseases will not be transmitted to customers or other members of the public.
2. Food health certificates are specially prepared for people engaged in food production and operation, such as restaurant chefs and workers in food processing plants. This is because these occupations are directly related to the handling and distribution of food, so the requirements for health status are stricter to ensure food safety.
