Additional Information: | Microbial profile of commercially manufactured as well as domestically prepared dahi on a small sample size was studied. The microbial profile of 6 dahi samples has been determined. Among the 6 samples, 3 were commercially manufactured dahi samples out of which one was procured from a local dairy and the remaining three were domestically prepared samples procured from homes. After determining the microbial profile, the dahi was challenged with 4 common pathogens, Escherichia coli, Staphylococcus aureus, Salmonella typhimurium and Listeria monocytogenes. The fate of these pathogens during the development of dahi and in the dahi itself as a post processing contaminant was studied by determining the survival and growth of these pathogens. Estimates of the counts of the pathogens as well as the pH at periodic time intervals after inoculation of the pathogen in the product were determined. In this study, an attempt has been made to study the safety of dahi during its manufacture and also after its preparation. |
