During the production and processing of cold chain food, an effective cleaning and disinfection system shall be formulated according to the characteristics of food raw materials and products, production and processing technology, processing personnel, production environment and relevant equipment and facilities, and the implementation and effect of disinfection measures shall be evaluated regularly. Specific disinfection objects include: food production and processing personnel, packaging of raw materials and semi-finished products, production and processing equipment and environment.

1.2 cleaning and disinfection during transportation and distribution

Among the four kinds of disinfectants recommended in "disinfectants commonly used in the production and operation of cold chain food" the author thinks that hypochlorite disinfectant is the most ideal disinfectant in the process of cold chain food processing. The details are as follows:

(1) Hypochlorite disinfectant is widely used in the production and processing, transportation and distribution, sales and management process, without frequent switching of various disinfectants;

(2) Hypochlorous acid as a food additive or used for cleaning and disinfection of food processing has been widely used and supported by laws and regulations in various countries in the world;

(3) The hypochlorite water is produced by the equipment in time, which is prepared and used on the spot, without deployment, and the operation is simple;

(4) there is already solid evidence that hypochlorite can kill COVID-19. After the outbreak of the disease, the National Institute of infectious diseases, the University of North Korea, Obihiro University of Agriculture and Veterinary medicine, Tottori University and QTEC testing center carried out an experimental study on the killing of COVID-19 by hypochlorite water. The results showed that below pH6.5, the effective chlorine concentration was more than 35ppm of hypochlorite (electrolysis / non electrolysis type). It can effectively kill New Coronavirus, and can be used as an effective disinfectant material against New Coronavirus.
