Razor clamming is open from Seal Rock north of Waldport near Beaver Creek to the California border, the Oregon Department of Agriculture and the Oregon Department of Fish and Wildlife announced.

Officials said recent samples showed levels of the marine biotoxin domoic acid have dropped below the closure limit. Razor clamming remains closed from the Washington border to Seal Rock for elevated levels.

Crab, mussel and bay clam harvesting remain open along the entire Oregon coast.

The Oregon Department of Agriculture said it will continue to test for shellfish toxins twice per month, as tides and weather permit. Reopening an area closed for biotoxins requires two consecutive tests with results below the closure limit.
