OLYMPIA, Wash. — State shellfish managers on Tuesday gave a green light for six days of razor clam digging on the Long Beach Peninsula after tests found the clams are safe to eat. The peninsula’s daily limit is being increased to 25 clams.

This means the Long Beach Razor Clam Festival will be able to proceed as planned this weekend, starting with clam-digging lessons Saturday at 6:45 a.m. and Sunday at 7:30 a.m. at the Bolstad Pavilion near the north end of the boardwalk.

Many other events are planned, including clam-related contests 8 a.m. to noon Saturday at Long Beach Dennis Co., clam chowder contests for amateurs and professionals from 11 a.m. to 3 p.m. Saturday at Long Beach Elks Lodge and a clam fritter cook-off from 3 p.m. to 5 p.m. Saturday at Veterans Memorial Park just east of the police station between Pacific Avenue and Oregon Street.

State shellfish managers agreed to increase the daily limit to 25 for the digs at Long Beach, which has been closed much of the razor clam season due to elevated marine toxin levels, said Dan Ayres, Washington Department of Fish and Wildlife coastal shellfish manager.

“We wanted to provide diggers with some additional opportunity at Long Beach since we know there are plenty of clams there for harvest,” Ayres said.

Recent tests found domoic toxin levels at all Washington ocean beaches met health standards, but the Washington Department of Health asked for one more test to be sure, Ayres said. That new set of samples taken Sunday all came back within safe limits of 19 parts per million or less.
