Geoduck Harvest Areas Cleared For Certification to China
Cleared Harvest Areas for Certification to China
Sampling and Analysis Protocol of Geoduck Clams for Shipment to the People's Republic of China
The US will implement the following sampling and testing to confirm the designation of harvest locations.
Sample Collection Sites per Harvest Location
Composite samples of three geoducks will be obtained from three locations in each designated harvest location for a total of nine geoduck clams.
Collection sites within a harvest location will be determined based on relevant factors including, but not limited to, harvest activity and access to the site. Collection sites and samples will be identified by Global Positioning Satellite coordinates and depth.
The US will analyze samples only for inorganic arsenic. Analysis will be conducted using the FDA-based for Specification and Measurement of Inorganic Arsenic in Shellfish Tissues by HPLC-ICP-DRC-MS. method.
Number of Geoducks per Collection Site
A sample will consist of 3 whole geoducks, including skin, gut ball, and meat. The 3 whole geoducks will be composited for testing.
If all three whole composite inorganic sample test results are below 0.5 ppm, the area will be cleared for export to China. A geoduck harvest area/tract will fail the arsenic test if one or more samples of the three composite samples collected from a specific harvest area/tract are >0.5 ppm for inorganic arsenic. If a geoduck harvest area fails the arsenic test criteria, another set of 3 composite clams from 3 sites within the harvest area may be submitted for testing. If the second test passes the opening criteria then the area will be cleared for export to China.
Maintenance Testing of Sites
Sites designated as acceptable for certification to China will be re-evaluated every year.
