A ban on harvesting oysters from particular areas in the Town of Oyster Bay has been lifted, the New York State Department of Environmental Conservation said Friday.

Effective at sunrise Saturday, harvesting of oysters will be permitted, the DEC said in a news release.

A previous ban on the harvest of shellfish other than oysters was rescinded Aug. 4.

The agency announced a ban on the harvest of all shellfish from the waters on July 12, after tests on hard clam and oyster samples from Oyster Bay Harbor by a Food & Drug Administration laboratory showed results a naturally occurring marine bacterium, Vibrio parahaemolyticus.

The bacterium is generally associated with warm water conditions and not with sewage or stormwater contamination of harvest areas.

Results of the last three sets of shellfish samples showed that Vibrio parahaemolyticus was no longer present in oysters at levels that are hazardous to human health, the agency said.

Information about temporary shellfish closures is available on a recorded message at (631) 444-0480. The message is updated when changes are made to temporary closures. Information also is at the DEC website, www.dec.ny.gov/outdoor/7765.html.
