Where does your food come from How is it made These days, many people worry about food safety. But food safety is not a new worry. In 1906, Upton Sinclair wrote The Jungle. The book is the story of a poor family in Chicago. It is also about the dangerous ways that food was prepared. People were so worried that the U.S. started testing food.
These days, most food in the world is safe. Laws control where food comes from. They also control how food is managed and prepared. Laws are important. But it’s more important to make sure the rules are followed. A good food safety system(系统) keeps people safe. It also helps them eat healthy food. Labels(标签) on food give people important information. Then they can make good choices about their food.
Although food safety systems usually work, there can be problems. Sometimes mistakes are made. For example, a truck might carry eggs and then ice cream. The ice cream could make people sick when the truck isn’t cleaned before carrying it. Other problems are not mistakes. Sometimes companies break rules to make more money. When this happens, people don’t know if their food is safe.
As we all know, food is closely related to our daily life. We should take action to make food safer!
