Enterococci can cause urinary tract infections, bacterial endocarditis, diverticulitis and meningitis.

Council installed signs at the lagoon advising residents that swimming was not recommended and further monitoring would be done.
Council said results from tests of the sea water at Cylinder Beach showed the samples were within the Healthy Waterways Healthy Waterplay guidelines.
