| Shellfish safety hotline |
|
The Oregon Department of Agriculture's shellfish safety hotline is toll free and provides the most current information regarding shellfish safety closures. The ODA Web pages may not be updated as quickly as the shellfish safety hotline. Please call the shellfish safety hotline before harvesting.
Shellfish safety hotline: 503-986-4728 or 1-800-448-2474 toll free.

|
| Recreational shellfish harvesting status as of 5/14/2012 |
|
- All shellfish harvesting is OPEN along the entire Oregon coast.
- The consumption of whole recreationally harvested scallops is not recommended. However, coastal scallops are not affected by this closure when only the adductor muscle is eaten.
Please note: The shellfish safety hotline is updated immediately when shellfish toxins reach the alert level. The hotline is your best source for up-to-date shellfish beach closure information. This Web page is updated soon after. For your safety, call the hotline before harvesting shellfish in Oregon.
This Web page provides an update of on-going shellfish safety closures on the Oregon Coast. This information will be updated monthly, or when there are new closures, openings, significant changes in shellfish toxin levels, or other events of interest to harvesters.

|
| What are shellfish safety closures? |
|
Shellfish can be contaminated by natural events such as harmful algae blooms (HABs) or man-made events such as sewage spills. The Oregon Department of Agriculture (ODA) and Oregon Department of Fish and Wildlife (ODFW) jointly issue shellfish safety closures to protect recreational shellfish harvesters from consuming clams or mussels contaminated with harmful biotoxins. However, because recreational shellfishing areas are not monitored for fecal coliform, ODA recommends you thoroughly cook all recreationally harvested shellfish prior to consumption.
Marine biotoxins -- paralytic shellfish toxins (PST) and domoic acid, are the most common reasons for shellfish closures in Oregon coastal waters. Biotoxins can cause mild to severe health problems for consumers. Visit one of the Web sites below for more information about marine biotoxins.

More information about Oregon’s shellfish resources
Commercial shellfish for human consumption, including oysters, clams and mussels, is part of the ODA Food Safety Division and the US Food and Drug Administration inspection and sampling programs. If you think you have become ill from consuming shellfish (commercially or recreationally harvested) seek medical assistance and contact your local county health department to report your illness.

|
|
| PST sample results are below the alert level |
|
Recent shellfish samples indicate levels of paralytic shellfish toxins (PSTs) are below the alert level in mussels and all other shellfish on the Oregon Coast from the Columbia River to the California Border.
Coastal scallops are not affected by PST when only the adductor muscle is eaten. The consumption of whole recreationally harvested scallops is not recommended.
Shellfish samples are collected regularly, as tides, weather, and surf allow. Warm ocean waters and calm seas are favorable conditions for a bloom of algae that produces PST. A shellfish safety closure is issued immediately if PST levels rise above the alert level of 80 micrograms per 100 grams. For the most current information please check the shellfish safety hotline: (1-800-448-2474).
Shellfish contaminated with PST can cause minor to severe illness or even death. PST cannot be destroyed by cooking, by adding baking soda, or by any other method of processing. PST symptoms usually begin with tingling of the mouth and tongue. Severe poisoning can result in dizziness, numbness and tingling in the arms and legs, paralysis of the arms and legs, and paralysis of the muscles used for breathing. PST(s) are produced by algae and usually originate in the ocean.

|
|
| Domoic acid results are below the alert level |
|
Domoic acid, the other shellfish toxin monitored for shellfish safety, is below the alert level in all shellfish on the Oregon Coast. All shellfish harvesting is open on the entire Oregon Coast from the California border to the Columbia River.
Coastal scallops are not affected by closures when only the adductor muscle is eaten. The consumption of whole recreationally harvested scallops is not recommended.
Shellfish samples are collected regularly, as tides, weather, and surf allow. A shellfish safety closure is issued immediately if domoic acid levels rise above the alert level of 20ppm. For the most current information please check the shellfish safety hotline: (1-800-448-2474).
Domoic acid is a naturally occurring toxin produced by marine phytoplankton or algae. Eating shellfish contaminated with domoic acid can cause minor illness within minutes or hours after consumption. The toxin is not destroyed by cooking, by adding baking soda, or by any other method of processing. In mild cases, symptoms can include vomiting, diarrhea, abdominal cramps, and headache. More severe cases can result in memory problems and even death.

| Commercial razor clam harvesting |
|
The Oregon Coast is now OPEN effective October 1st, 2011 to commercial razor clam harvesting along all Clatsop Beaches. The ODA has authority to restrict the distribution of shellfish sold by commercial processors and will halt distribution if sampling indicates that clams are above the alert level for either biotoxin (20 parts per million (ppm) for domoic acid and 80 micrograms per 100 grams for PST). People are more likely to suffer illness from eating shellfish with high levels of biotoxins. Harvest controls are implemented when biotoxins reach the alert level, thereby reducing the risk to consumers. Shellfish samples are collected regularly, as tides, weather, and surf allow.

| Harmful algae bloom monitoring |
|
ODA and ODFW monitor for the toxigenic alga or plankton that produce domoic acid and PST. Zach Forster, phytoplankton sampling coordinator with the ODFW, reported the following on September 29th, 2011:
A coast wide decrease of Pseudo-nitzschia cells was observed this week. The most dramatic decreases were at Gold Beach which went from 484,000 cells/L on 9/20 to 26,000 cells/L and all of the Clatsop Beaches which went from 200,000-300,000 cells/L to no detectable cells.
Along the central coast cell counts of the smallest sub-type of Pseudo-nitzschia decreased to 74,000 and 33,000 cells/L respectively at Agate Beach and Bob Creek Wayside.
Coos Bay area samples were all well below 5,000 cells/L. of Pseudo-nitzschia.
Overall diatom numbers were down with the exception of Clatsop Beach which had some high density areas of Asterionellopsis socialis giving off the appearance of a brown oily sheen in the surfzone.
