Use shopping baskets and metal shopping carts correctly. Since the trolleys in most stores are used very frequently, they rotate in the hands of customers all day, and there is no time for cleaning and disinfection. The data shows that the detection rate of mold at the bottom of supermarket shopping baskets reached 69%, the detection rate of coliform bacteria reached 51%, and the detection rate of molds at the bottom of trolleys reached 37%. In public shopping in supermarkets, once customers’ hands are contaminated with bacteria on the trolley, they may be transferred to the food during the selection process. It is recommended to bring a pack of disinfectant wipes when you go to the supermarket. Before using the shopping cart, you can wipe it with a wipe first. Don’t let the children sit in the trolley. Don’t put cooked food on the bottom.
Finally buy raw meat and frozen food. General supermarkets strictly divide fresh food, meat and daily necessities, allowing customers to buy frozen and fresh products in the future. But in life, many people do not pay attention to the order of shopping, first go to the meat department to buy things, and then buy other things. Due to the high temperature in the supermarket, fresh food will breed bacteria after thawing, and it will also contaminate the shopping basket and cause cross-infection.
Eat less cooked food that you can try at will. Most cooked food is outside without any lid. Customers can pick them up by hand. People who process cooked food do not wear masks. These are the unsafe factors of cooked food. The Guangzhou Center for Disease Control and Prevention inspected some supermarkets and found that among 32 cooked food samples, the total number of bacterial colonies and coliforms in 21 samples exceeded the requirements of the national standard, and the unqualified rate was as high as 84%. It is recommended not to try free cooked food. The cooked food purchased should be cooked and disinfected before consumption and consumed within 2 hours. Cooked food overnight or refrigerated must be heated before reaching the food center, so that the innermost items can be placed on the shelf. The survey found that the products on the outer shelf are most often picked up, but not every customer can buy them. It easily produces various skin oils and bacteria. It is recommended to place the product on the innermost shelf.
Wash your hands immediately after returning home. Although the bacteria in the supermarket will not cause direct harm to the human body, if you eat the bacteria with dirty hands, you are very susceptible to infection, especially children. So wash your hands immediately after visiting the supermarket.
