Dear Editor,
I'm writing to tell you about a food poisoning accident. Several days ago, my neighbor ate a bag of food buying from the market. After the meal, they had stomachaches and their faces turn pale. Lucky, one of their friends found the accident and immediately called an ambulance, which carried them quickly to a hospital. After several hours' treatment they finally escaped of death.
As some businessmen are only interested in making money to become rich quickly, we seldom care about the necessary safety measures or which happens to buyers. They must be have charged by law. Meanwhile, I do hope whole society can realize the important of food safety.
