How often does the cold storage be disinfected?

Cold storage uses refrigeration technology to achieve the purpose of refrigeration or freezing. Since the temperature inside the cold storage is low, the growth and reproduction of microorganisms can be inhibited, so the food inside the cold storage can be preserved for a long time.

However, since the environment inside the cold storage is relatively humid, it is easy to breed microorganisms such as bacteria and viruses, so it needs to be disinfected regularly. Generally speaking, the disinfection time of the cold storage needs to be determined according to the actual situation. Under normal circumstances, disinfection is required once a month, but it needs to be disinfected once a week in the hot and humid season in summer.

In addition, if the cold storage is storing perishable and perishable food, such as meat, fish, vegetables, etc., it needs to be disinfected before each storage. If low-temperature milk, ice cream, and other foods are stored, they also need to be disinfected once a week. When disinfecting the cold storage, the following points need to be noted

• Selection of disinfectants: Choose disinfectants that are harmless to food and meet relevant standards.
• Selection of disinfection methods: Choose appropriate disinfection methods according to actual conditions, such as ultraviolet disinfection, spraying disinfectants, etc.
• Selection of disinfection timing: Disinfect before storing perishable and perishable food in the cold storage and disinfect in time after storage.
• Check the disinfection effect: After disinfection, the disinfection effect needs to be checked. If it is unqualified, it needs to be disinfected again.
