one scraping, two washing, three flushing, four disinfection and five cleaning.

1, tableware disinfection should meet the following requirements:

(1) Thermal disinfection: boiling steam at 111℃ for 31 minutes.

(2) Far infrared at 1.21℃ for 1.5 ~ 21 minutes.

(3) drug disinfection: the concentration of available chlorine is 251PPM, and the disinfection time is 5 minutes.

2. Disinfected tableware, tea sets, etc. should be immediately placed in clean cabinets and cabinets for cleaning to prevent re-pollution.

Disinfection misunderstanding

For tableware, high-temperature boiling is indeed the most common disinfection method, and many germs can be killed by high-temperature disinfection. However, in order to achieve the real effect, high temperature disinfection must meet two conditions, one is the temperature of action, and the other is the time of action.

There are many kinds of microorganisms in intestinal infectious diseases, and the bacteria that often cause acute diarrhea include pathogenic Escherichia coli, Salmonella, Shigella, Vibrio cholerae, Bacillus cereus and so on.

Most of these bacteria can only die after being heated at 111℃ for 1-3 minutes or at 81℃ for 11 minutes. If the heating temperature is 56℃, these bacteria can still survive after 31 minutes. In addition, some bacteria have stronger resistance to high fever, such as anthrax spores and waxy spores.

Therefore, boiling the bowl with boiling water before eating can only kill a very small number of microorganisms, but it is not guaranteed to kill most pathogenic microorganisms because of insufficient temperature and time. To achieve the effect, boiling, circulating steam or sterilizing the cupboard with infrared rays are all optional methods. If boiling is used, if you want to really disinfect, you must cook for a while. It usually takes 1.5-31 minutes to disinfect the cupboard with infrared rays.
