Was Arsenic found in the DOH Health Consultation
from 1997 important to pay attention to?
The Washington Department of Health (DOH) has clarified further that the geoduck which the Chinese state tested positive for Arsenic originated in Puget Sound and those testing positive for Paralytic Shellfish Toxin (PST) - also referred to as Paralytic Shellfish Poisoning toxins (PSP) - originated from Alaska. DOH will begin further testing of geoduck tissue in the area.

Arsenic in geoduck tissue
Tract 10400 is adjacent to 10380 where
it is believed geoduck testing positive
for Arsenic by the Chinese originated from.
1997 testing for Arsenic by Department of Health
EVALUATION OF SELECTED METALS IN GEODUCK TISSUE FROM TRACTS 09950 AND 10400 DUMAS BAY, PUGET SOUND, KING AND PIERCE COUNTIES, WASHINGTON (April 18, 2007)

In 1997 a Health Consultation report tested geoduck for Arsenic and other heavy metals from geoduck samples in tracts 09950 and 10400. Those tests showed Arsenic levels in geoduck ranging in levels from 2.28 parts per million to 5.02 parts per million (see page 7 of the report referenced above). Whether this should have been significant enough to have alerted DOH to additional testing is an open question.
