Food safety precautions:

When buying food and drinks in shops and supermarkets, we should pay attention to whether there is a manufacturer, production date, expiration date, labeling of food raw materials and nutrients, and QS logo on the food packaging. Can't buy three no products.

Open the food package and check whether the food has proper sensory characteristics. Do not eat foods that are spoiled, rancid, moldy, insect-borne, filthy, mixed with foreign bodies or have other sensory abnormalities. If the food in protein is sticky, the fatty food has a whistling smell, the carbohydrate has a fermenting smell, or the beverage has abnormal sediment, you can't eat it.
