Clostridium species is a food contaminating anaerobic bacteria causes food poisoning and spoilages in milk and milk products. A total of 200 samples were studied for the presence of Clostridium species in raw milk, curd, cheese and paneer samples in which 62(31%) sample showed positive growth for Clostridium species. Out of these 62 Clostridium isolates 22(35.48%) were confirmed as Clostridium perfringens, 21(33.87%) Clostridium sporogenes, 12(19.35%) Clostridium butyricum and 7(11.29%) were confirmed as Clostridium tyrobutyricum. In the present investigation the milk and milk products showed the high occurrence of Clostridium perfringens which is 26% in raw milk. The study shows the existing contamination in dairy products which is the hazardous for the human health as the contamination of Clostridium species is responsible for the food poisoning and food spoilage in certain products.
