1, when buying food, pay attention to whether the food packaging has the manufacturer, the production date, whether the shelf life has passed, whether the food raw materials and nutrients are marked, and whether there is a QS logo. You can't buy three-no products.

2. 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.

3. Don't buy lunch boxes or food from unlicensed vendors around the campus to reduce the hidden dangers of food poisoning.

4. Pay attention to personal hygiene, wash your hands before and after meals, wash and disinfect your own tableware, don't put food in unclean containers, and don't litter in the canteen to prevent mosquitoes and flies from breeding.

5. Eat less fried and fried food.
