Swimming is not recommended for those attending that area of the beach until the advisory has been lifted.

Health officials said contact with the water may mean an increased risk of infection due to higher than usual levels of the Enterococci bacteria. That type of bacteria is found in human and animal intestinal tracts. It can cause gastrointestinal illness, upper respiratory infections, or skin infections of open wounds or sores.

Health officials believe the spike in bacteria levels may be a natural variation but they will lift the advisory when the bacterial levels drop.
