Currently, during the unusual period of Nanjing's fight against the COVID-19, ensuring supply and stabilizing price have become bottom-line barriers to secure the lives of residents and maintain the safe operation of the city. In the special period, compared with ordinary food markets, large supermarkets for one-stop shopping and community groceries at the doorstep have become the best choice for more residents to buy daily food and necessities. The work of guaranteeing supply during the unusual period must not only ensure sufficient supply, but also strengthen the awareness of risk protection, so that the guaranteed goods can reach residents' homes and tables safely and conveniently.The main risks in the current retail link of guaranteed goods include: crowded people are likely to cause cross-infection, convenient facilities probably lead to virus transmission, space confinement is not conducive to air circulation, cooked food processing is difficult to prevent and control viruses, and the phenomenon of large passenger flow in community fresh stores is obvious.Therefore, it is suggested to strengthen the end-of-community supply, reduce the hidden dangers of crowded shopping, and meanwhile strengthen the epidemic prevention and control of large supermarkets and community fresh food stores to reduce the risk of cross-infection.
