DEC: Harvesting of Shellfish, Carnivorous Gastropods Temporarily Closed in Parts of Riverhead

The New York State Department of Environmental Conservation (DEC) announced on Thursday that the harvesting of shellfish and carnivorous gastropods in particular areas in the Town of Riverhead have been temporarily closed.

The closure comes due to the detection of a marine biotoxin.

The closure impacts approximately 100 acres in the Town of Riverhead, covering all the underwater lands in Terry Creek and Meetinghouse Creek, tributaries of Flanders Bay.

All harvesting of shellfish and carnivorous gastropods in these lands is prohibited until further notice.

This action was taken after DEC determined that shellfish collected from monitoring sites in Meetinghouse Creek tested positive for saxitoxin, a marine biotoxin that causes paralytic shellfish poisoning (PSP).

The samples were tested as part of DEC’s marine biotoxin monitoring program.

Carnivorous gastropods (whelks, conchs, moon snails) feed on shellfish and may accumulate biotoxins at levels that are hazardous to human health.

DEC will continue to monitor for the presence of biotoxins in shellfish at 13 monitoring locations around Long Island and implement closures as necessary to protect public health.

Marine biotoxin has also been detected in areas within the Town of Southampton which have also been closed to harvesting on Thursday.

A recorded message advising harvesters of the status of temporarily closed shellfish areas may be heard by calling (631) 444-0480. The message will be updated during the course of the temporary closure.
