Objective To explore the distribution of Clostridium botulinum in environment，so as to provide scientific basis for the prevention，diagnosis and treatment of food borne botulism in Shijiazhuang district. Method According to the landform，350 soil，water and food samples from 8 areas of Shijiazhuang were evenly collected for testing Clostridium botulinum.
