First of all, don't eat unclean fruits and vegetables. During the growth of melons and fruits, pesticides need to be sprayed, fertilized and watered. In the process of treatment, harvesting and sales, some drugs need to be sprayed for preservation at some stages, and even some merchants like to wax and spray preservatives on the surface of the peel. These processes are also susceptible to bacterial infection, so some melons and fruits bought from supermarkets and fruit markets will carry eggs, bacteria and chemical pesticides on their surfaces. Wash it with clear water several times before eating. All peelable fruits should be peeled before eating to prevent food poisoning.
Secondly, we should pay attention to good eating habits. Wash your hands before and after meals, because touching your hands every day is easy to infect viruses, germs and parasitic eggs. Wash your hands with disinfectant soap or hand sanitizer before eating. Wash hands properly, and clean palms, backs of hands, wrists and fingers. Don't eat wild vegetables and fruits you don't know, and don't eat moldy and rotten food, because there are a lot of bacteria in it, which will cause food poisoning.
Finally, don't eat inferior snacks and drinks. There are always some primary school students who especially like the canteen near the school. There are some small snacks of 50 cents each, which are very heavy and make primary school students crazy. But the sanitary quality inside is mostly unqualified. Students will have stomachache, malnutrition and even endanger their health after eating.
In daily life, we should also pay attention to not drinking raw water, drinking more boiled water, drinking less drinks and not buying food without a business license.
