The quality of dairy products has a significant influence on consumers’ health. In recent years, dairy products safety scandals occur frequently, which not only impair the confidence of domestic consumers, but also hit the dairy industry heavily. There are some reasons. First, the social bases led to the frequent occurrence of dairy products security incidents. Second, the long industry chain of dairy production, the numerous links which were full of quality safety risk, and the fragmented cultivation of dairy cattle make it difficult to guarantee the quality of raw milk. Last but not least, the subjective factors, such as lacking of regulation and insufficiency of cracking down illegal act also lead to the frequent scandals. To ensure quality and safety of dairy products, the quality and safety of raw milk must be assured in the first place. Secondly, in order to guarantee the quality of dairy products, the dairy enterprises must establish effective controlling system. Third, the government should strengthen legislation, and monitor the quality and safety of dairy products constantly. In particular, the government should strengthen regulation and crackdown of making adulterated milk and other illegal activities.
