I will share with you true story that happened a couple of day ago. One of my classmates bought a bag of snacks from a food store. A few classmates were then inviting to enjoy the snacks. Unluckily, all of us got poisoned and had stomachaches with their faces pale. They were 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 makes us to realize the seriousness of the food safe problem. Therefore, I strong suggest that the whole society pays more attention to it.
