Abstract
Foodborne microorganisms can lead to serious outbreaks in the community, hence food safety is vital for the consumer. This study was focused on microbiological assessment and characterization of bacteria associated with dairy carabao's milk-based bibingka sold in local dairy cooperatives. Physical assessment of the product was performed prior the bacteriological assessment. Conventional method and Petrifilm tm was used in enumerating microorganisms. Aerobic plate count, presumptive confirmatory and completed coliform and E. coli enumeration were utilized for the conventional method while Petrifilm Anaerobic Count Plate and Petrofilm tm E. coli/ Coliform Count Plate was used in 3M Petrifilm.
The physical assessment of the product showed no objectionable traits in terms of color, color, appearance and taste. Results showed that within the two samplings, the dairy carabao's milk-based bibingka satisfied some of the given standards for its properties. Parallel results obtained among conventional methods and Petrifilm tm for analyses of aerobics, total coliforms and Escherichia coli. Three isolates were the food-prevalent bacteria that appeared in both samplings. three Gram positive bacterial isolates were characterized based on its cultural and morphological characteristics.
