The Southampton Town Trustees are advising beachgoers ahead of the summer about flesh-eating bacteria following a News 12 report on the bacteria present in several bodies of water on Long Island.

They say the presence of the bacteria is not uncommon, and it is mainly seen in warm saltwater or brackish places during warmer temperatures.

As previously reported by News 12, new research from Stony Brook University says several locations are effected, such as Sagaponack Pond, Mecox Bay and Georgica Pond.

"People who are infected with this bacteria have a 20% chance of dying within just 48 hours following infection," said Chris Gobler, a professor at Stony Brook University.

May through October is typically the peak time the bacteria is found.

"This advisory is intended to encourage caution, not alarm," the trustees wrote, "With sensible preventive measures, residents and visitors can continue to safely enjoy the Town’s treasured waterfronts throughout the season."

Infections are rare, but become serious quickly, especially for those who are older or have underlining health conditions.

Most infections enter an open wound such as recent cuts, scrapes, surgical wounds, piercings, tattoos or skin irritations.

Gobler says the biggest cause of the bacteria is years worth of nitrogen running into the water from onsite septic systems.

To combat the bacteria, researches are using increased shellfish and seaweed to absorb the nitrogen.

Suffolk County officials say they are working on upgrading septic systems.

The Southampton Town Trustees say they will continue coordinating with health authorities and monitoring conditions.
