ABSTRACT. Assuring food safety is currently a global challenge. Frequent testing of food samples for the presence of microorganisms should be performed as part of any food safety program. The conventional tests are in general laborious and time consuming. In this context, the use of alternative rapid tests becomes important. The objective of this study was to compare the performance of Petrifilm test method and standard colony count method for enumerating aerobes, Coliforms and Escherichia coli. The Aerobic Plate Count (APC), Coliform Plate Count (CPC) and E. coli obtained using Rapid Petrifilm test method were compared with the corresponding standard methods using 24 samples of 3 different foods, namely poultry, ready to serve drink (RTS) and milk powder. The counts obtained using Rapid Petrifilm method were not significantly (p
