The widespread number of food scandals （丑聞） in China is making many people pause before they put their chopsticks in their mouth．They are wondering if the food they are eating is clean，healthy and nutritious（有營養(yǎng)的） or does it contain（包含） something harmful that will cause diseases？
Most of the food we eat today is processed food（加工食品）．That means the foods we buy in stores and supermarkets，especially packaged foods，are prepared in factories．Chemicals are added to the foods in these factories to make them look better，taste better and last longer on the shelf．The chemicals（化學制品） are supposed to be harmless and there are laws that control which chemicals can and cannot be used．Unfortunately，some producers do not obey the laws．
A producer of steamed buns（饅頭）in Zhejiang Province was recently discovered to be breaking the law．He was adding yellow dye（染色） and other banned chemicals to the buns．He was also taking old buns and using them to make new buns．Most of the buns were sold to schools and eaten by students like you．
Why did he do it？Why did he break the law and endanger people's health？The answer is simple：he wanted to make more money．It was a moral failing（道德滑坡），and this is at the heart of the food scandals in China．Too many people focus on（集中于） making money and not on the effects their actions can have on others．
