This research study focuses on identifying the bacterial count of Escherichia coli among Perna viridis (Asian Green Mussels) as well as the waters that surrounds their place of production. A total number of 90 mussel samples were used together with six (6) water samples located in six sites in Cavite. Twelve (12) trials in the mussel samples and 27 water samples were identified to have growing contamination of Escherichia coli on both Perna viridis and seawater. Upon knowing these results, the researchers conclude that there is a significant correlation between the most probable number per 100 mL (MPN/100mL) of the water and the colony forming units per mL (CFU/mL) of the mussels per sample.
