The Onondaga County Parks Commissioner has closed Oneida Shores Beach to swimming in the Town of Cicero, due to high levels of E-coli bacteria in the water.

Swimming will not be allowed until those bacteria levels return to acceptable levels.

County Parks Commissioner Bill Lansley says the Health Department monitors lake water routinely and closes swimming when bacteria levels exceed standards.

Most varieties of E-coli are harmless or cause brief diarrhea. While only some types of bacteria will cause gastrointestinal illness, the presence of E-coli is an indicator of increased general bacterial action in the water.

Anyone concerned about gastrointestinal symptoms shold contact their health care provider.

This is the second ime in one month the County Parks Department has closed Oneida Shores Beach because of high levels of E-coli bacteria.
