containers that will not pollute food can be placed in the food warehouse. According to the Food Safety Law, the Regulations for the Implementation of the Food Safety Law and the Measures for the Supervision and Administration of Food Safety in Catering Services, it is shown that food and non-food warehouses (except food containers, packaging materials and tools that will not cause food pollution) should be set up separately, and the storage areas of foods and articles with different properties in the same warehouse should be divided, and different areas should be clearly marked. Food storage warehouses and storage facilities, such as refrigerators and storage racks (cabinets), should be set up according to different scales and operational needs. Storage places, containers, tools and equipment should be safe and harmless, and kept clean. Screens, rat nets and rat boards should be set up to effectively prevent rats, insects, flies and cockroaches, and toxic and harmful articles and personal daily necessities should not be stored.
