I will share with you a story happened a few days ago. One of my classmate bought a bag of snacks from a food store. A few roommates were then invited to enjoy snacks. Unluckily, all of them got poisoned and had stomachaches with our faces pale. They are quickly sent to a nearby hospital. Doctors examined them but gave them some medicine. They were out of danger soon before taking the medicine. This accident should make us to realize the seriousness of the food safety problem. I strong suggest that the whole society pays more attention to food safety.
