Background Aerobic spore-forming bacteria can be found in a wide range of environmental niches suchas food production. Among them, the aerobic spore-forming bacteria like Bacillus ceruse, pose a risk ofcausing dairy product poisoning by the production of toxins.Materials and Method: Out of 40 samples, 10 from each of Raw Milk, Skim Milk Powder, UHT Milk andWight chees were collected to isolate aerobic spore-forming bacteria by morphological, physiological andbiochemical tests.Conclusion: A total of 25 isolates of heat resistant bacteria, 10(40%), 8(32%), 3(12%), 4(16%) from “RM,white chees, SMP and UHT milk respectively,” were purified and characterized. Various spore formingbacteria belonging to Bacilli spp. which include pathogenic were biochemically identified using vitek 2systems, the result showed the highest rate of Bacillus subtilis (28%) followed by Bacillus ceruse andBacillus thuringiensis (24%).
