The contents of food safety are as follows:

1. Pay attention to personal hygiene, wash your hands before and after meals, rinse your mouth after meals to maintain oral hygiene, and use public spoons and chopsticks for group meals.

2. Eat slowly, which is more conducive to the digestion and absorption of nutrients, concentrate on eating, and don't make jokes.

3. Don't buy food from unlicensed mobile stalls around the campus or in the streets and alleys. Choose carefully when eating outside the school. Choose a clean and well-certified catering service unit and ask for a formal invoice or receipt. Don't eat in unlicensed catering units. It is recommended to choose a catering service unit that practices "bright kitchen and bright stove".

4. Don't be picky about food, be partial to food, be anorexic or overeating, and match three meals a day with vegetarian food to scientifically supplement the body's nutrition.

5. Wash raw fruits and vegetables. Fruits and vegetables with skins should be peeled as much as possible.

6. Do not eat foods that are spoiled, rancid, moldy, infested, or mixed with foreign objects. If you lose the original appearance, shape, and smell of the food, you must pay attention to separate them carefully and smell the rotten smell. Don't be reluctant to throw them away. You must pay attention to them.

7. For foods whose prices are obviously lower than the general price level, most of the foods whose prices are too low are "fishy". Temporary food can be eaten as little as possible or not, depending on the food situation.

8. Eat less food in bulk. Bulk refers to soy products, cooked food and pickles in some markets, which may come from underground processing plants or places with poor sanitation.
