Abstract
|
|
|
|
This study was performed to compare the efficiency and accuracy of Sanita-Kun dry medium with those of conventional culture and Petrifilm dry medium methods for enumerating coliforms and Escherichia coli in milk, ice cream, ham, and codfish fillet. All 3 methods showed high correlations each other and no significant differences in enumerating coliforms and E. coli. In addition, the Sanita-Kun method was easier to count microbial load than the Petrifilm method. Therefore, we concluded that the Sanita-Kun method can be used as an alternative to conventional culture and Petrifilm methods for the analysis of coliforms and E. coli in milk, ice cream, ham, and codfish fillet products.
