Three people who ate raw or partially cooked shellfish in Nassau County became ill recently, and an additional five illnesses were reported to the New York State Department of Environmental Conservation (DEC) by three other states that received shellfish harvested in Oyster Bay.

Laboratory tests have determined that the illnesses were caused by the marine bacteria, Vibrio parahaemolyticus.

A map showing the affected closure areas is available at the DEC website at http://www.dec.ny.gov/outdoor/7765.html.
