Do isothermal containers need to be disinfected and sterilized?

Disinfection and sterilization isothermal containers are usually optional, but may be beneficial in some cases. The following are some reasons why it may be necessary to disinfect and sterilize isothermal containers in certain situations:
Storing food or liquids for a longer period of time: If you plan to store food or liquids in a isothermal container for a longer period of time (such as more than a few hours or a day), disinfecting and sterilizing the container may be beneficial as it can kill any potential bacteria or microorganisms, maintain the freshness and safety of food or liquids.
Poor environmental hygiene: If you bring a isothermal container to outdoor activities or other places with poor environmental hygiene, the container may be contaminated by the external environment. Therefore, disinfecting and sterilizing the container is a preventive measure that can reduce the risk of food or liquid contamination.
Containers have previously stored fresh food: If a isothermal container has previously stored fresh food, such as meat, seafood, or vegetables, it is important to disinfect and sterilize the container before storing other food to prevent cross contamination.
Other special circumstances: In some special circumstances, such as the container has been used by people with infectious diseases, or the container has stored potentially contaminated liquids (such as toxic substances or chemicals), disinfection and sterilization of containers may be necessary.
However, for general daily use, as long as the isothermal container is cleaned in a timely manner and kept hygienic, it can usually be maintained in good working condition. Disinfection and sterilization containers are usually additional steps carried out under specific circumstances, which can be determined based on personal preferences and the actual usage environment.
