Samples of sheep milk (n = 30) were plated simultaneously, to enumerate mesophilic aerobes, total coliforms, lactic acid bacteria, Staphylococcus aureus and Escherichia coli, using convencional reference protocols and Petrifilm™ plates.
The results were compared using McNemar’s test, linear regression and ANOVA (p 0,05).
The results demonstrated good significant between conventional methodologies and Petrifilm™ plates.
Further, the Petrifim™ STX for counting S.  aureus had higher recoverability of bacteria...
