Frozen food is special, production and storage are generally carried out at low temperature, so there are many frozen drinks, including ice cream, ice cream health department samples, popsicles, ice cubes and so on. Using frozen drinks to test, it was found that most of the unqualified samples were edible ice from catering units.

Through analysis, the health department found that the reason for low power consumption was that the filter screen of the edible ice machine was not cleaned and disinfected; The storage area of ice machine has poor sanitary conditions; The ice shovel mixes ice in the ice maker, which greatly increases the pollution of the ice shovel. The cleaning and disinfection work of the food and beverage department does not pay attention to the ice machine.

How to judge whether it is safe to eat ice? One of the easiest ways is to see that its packaging is a "QS" market access sign. According to Li Guilin, director of the Food Safety Division of the Quality and Technical Supervision Bureau of Longtan District, Jilin City, the requirements and technical specifications for making edible ice are very strict, and the water has to pass through thick porous filters, activated carbon filters, ultraviolet sterilization and ultrafiltration filtration. The process enters the ice machine. In addition, it is equipped with disinfection equipment and laboratory equipment. "Only when these conditions are met can the relevant departments handle the relevant procedures.
