There are four major problems existing in China's food safety supervision and management. They are imperfection in the system of laws on food safety, obvious defect of current criminal law governing food safety crimes, insufficient understanding for supervisory staff to hazard of food safety crimes, absence of workable accountability system for supervisory staff who spoil their duty. Those existing problems have caused frequent crisis of food safety. To tackle these problems, a legally governing system, which should be mainly supported by the system of criminal law, needs to be established to unify names of crime for food safety crime and to perfect social supervisory preventive system.
