This study reports the occurrence of Escherichia coli in 243 mussel samples collected along the Boka Kotorska Bay (six harvesting areas), which is located in the Southern Adriatic Sea. Bivalve molluscs can concentrate contaminants from their water environment, so because of that, determination of E. coli levels is an important parameter for microbial pollution assessment in the investigated areas. The number of E. coli ranged between 4600 MPN E. coli /100 g. Statistical analysis of the number of E. coli in mussels established that the mussel farm vl. Duško Vlahović (M5) had the highest mean E. coli levels (949.00 ± 2541 MPN E. coli /100 g), while the lowest mean level was recorded in Boka mussels (M1) (149.20 ± 258.80 MPN E. coli /100 g). Boka Kotorska bay is classified as a Class B mussel production area because it has 32.9% of samples with E. coli MPN values between the 20-230 MPN/100g.
