上海加强冷冻食品疫情防控 - 2020年11月19日

Local health authorities are calling on the public to be cautious of cold-storage foods, especially imported foods, after confirmed cases of coronavirus contamination involving such items.
Shoppers are recommended to go to official supermarkets and wet markets, and pay attention to the origins of their food, as well as inspection information on imported food.
Avoiding direct hand contact with frozen food and wearing disposable gloves and masks is suggested. Using separate packages for food and keeping raw and cooked food in different parts of the refrigerator are also useful to prevent the spread of the virus, said Shanghai Health Promotion Center.
