According to the relevant regulations, those who apply for on-site production and sale of cold food should set up corresponding production rooms, and those who apply for homemade drinks should set up special business premises, but it is not clear whether they can be used. Special rooms and special operation areas belong to clean operation areas. According to the fact that the catering unit where the consultant works uses fewer varieties of cold food to process, it is impossible to set up a special room and a special operation area separately. If the following necessary food safety measures can be guaranteed, the operation of homemade drinks can be included in the cold food production and sales room: food raw materials must be cleaned before being transferred to the special room, and when the finished products are processed in the special room and the special operation area, the production and sales of homemade drinks and cold food can be set up in the special room for partition operation; Formulate and implement the "Food Safety Management System for Special Rooms" and related risk control measures: the food entering the special rooms should be directly imported food, food packed in cartons and other raw materials, and the shells and skins should be removed and washed before entering the special rooms; Do not engage in other activities that may contaminate food underground to prevent food from being contaminated in special rooms; Employees should wear work clothes and masks and strictly implement personal hygiene requirements.
