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, an American writer wrote The Jungle. The book is about the danger in the ways that food was prepared. People were so worried that the US started testing food.
These days, more things are done to make food safe. Laws control where food comes from. They also control how food is managed (管理) 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 improve a lot, 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 in order to make more money, it’s probable for companies to break rules. When this happens, people don’t know if their food is safe.
As we all know, food is closely related to our daily life. If we don’t take action to make food safer, we will never have healthy food to eat.
Food safety has always been a worry to people. In 1906, an American writer wrote about the However, although people make many great Food has a close relationship with our daily life. |
