"PSP toxins in scallops are not a health risk."
There is nothing incorrect or wrong about that statement. The 'main' quoted death was
"On the evening of June 25, while aboard a fishing boat, the decedent had consumed 25-30 steamed butter clams and 2 teaspoons of butter clam broth." but it should also be noted that
"Two other crewmembers had also consumed butter clams. One developed numbness and tingling of the face and hands and dizziness approximately 1 hours later and recovered uneventfully; the other had no symptoms. Four crewmembers from two other fishing boats also had shared the butter clams presumed to be the vehicle for illness; all four had symptoms consistent with PSP. "
One didn't have any symptoms, the others were affected.
The level of this toxin is set at "(maximum safe level: 80 ug/100 mg)"
I do think that someone might suffer from other complaints before ever consuming 1 cwt of scallops [or whatever, spuds]
www.uncommonsportsman.com/2010/6/6/1504496/sonya-black-widow-thomas-defends PSP is endemic, they a bottom feeders.
'effecting over 150 people' bad sums by the looks of it "From 1976 through 1989, 42 PSP outbreaks (accounting for 94 cases)"
from the quoted .pdf doc....
"Symptoms of 143 people with paralytic shellfish poisoning, Alaska, 1973-94"
For completeness the test....
"Only a mouse bioassay is approved by the U.S. Food
and Drug Administration for detection of PSP toxins. The
test procedure first extracts PSP toxins from 150 grams of
shellfish tissues. The extract is injected into 3 Swiss
Webster strain white mice 18-23 grams in weight. The
amount of time required for the mice to die is recorded then
converted to micrograms (mg) of toxin by substitution into a
prescribed mathematical formula."
Remember this is for Alaska, according to Google Earth 3,300 + miles 'as the crow flies', away from N Scotland, on the Eastern seaboard of the American continent, half? a world away. Some different condition s might apply.
