Razor clam harvest ban lifted for northern Oregon coast amid shellfish toxin scare

Oregon fish and wildlife officials reopened the northern Oregon coast for razor clamming last week while keeping a prohibition in place south of Yachats and continuing a coastwide ban on harvesting bay clams and mussels.

The Oregon Department of Fish and Wildlife had closed the entire coast to shellfish harvesting earlier this month because of a potentially deadly toxin, paralytic shellfish poisoning, or PSP, that had sickened at least 20 people who had eaten Oregon coast mussels.

No one is reported to have died in the outbreak, but some were hospitalized, according to Oregon health officials. Naturally occurring marine toxins are not eliminated by cooking or freezing.

Officials said Friday that two consecutive tests had shown razor clams in the newly reopened area were below the threshold at which harvesting is banned due to biotoxins. They said the earlier closure was precautionary, and that testing had not detected biotoxin levels above the closure threshold.

However, razor clamming is closed from the Yachats River to the California border, where tests have detected high levels of paralytic shellfish poisoning and domoic acid.

Harvesting bay clams and mussels remains prohibited along the entire Oregon and Washington coast.

The state also has reopened commercial oyster fisheries in Tillamook Bay and Netarts, while the Umpqua River/Winchester Bay commercial oyster fishery remains closed. Crab harvesting is open for the length of the Oregon coast.

The Oregon Department of Agriculture operates a toll-free shellfish biotoxin hotline 800-448-2474​ and maintains a list of closures on its website.
