shellfish safe to eat?


wondering about safety of the clams this time of year from the pacific. can you cook out the "potential" poisons. i don't think so, but i wanna check. gonna get some pismo's for bait anyway so i might grab a few extra for a clam linguini on the beach.

If you Google


the correct keywords you'll see that algal blooms occur in Baja regularily. If you witness this I would refrain from eating bivalves for a period of time. Cooking does not prevent poisoning.

The rule of thumb I always go by is if there is an "R" on the month it is OK to eat the shell fish (Ie SeptembeR through ApRil). Algae blooms are more common in the Summer's warm water and it is the toxicity in contained in the algae that the shell fish concentrate that causes the Toxic Shellfish Poisoning. Cooking will not remove it.

If you like to gamble, go ahead and eat, most people do not die from it......and some of the symptoms are the same as drinking too much Tequila :lol:

Quote:
Paralytic Shellfish Poisoning

PSP is a marine toxin disease with both gastrointestinal and neurologic symptoms reported worldwide. It is caused predominantly by the consumption of contaminated shellfish.

Gonyaulacoid dinoflagellates are the source of PSP marine toxins.These unicellular dinoflagellates develop algal blooms.....

Five to 30 minutes from consumption, there is slight perioral tingling progressing to numbness which spreads to face and neck to moderate cases. In severe cases, these symptoms spread to the extremities with incoordination and respiratory difficulty. There are medullary disturbances in severe cases evidenced by difficulty swallowing, sense of throat constriction, speech incoherence or complete loss of speech, as well as brain stem dysfunction. Within 2-12 hours, in very severe cases, there is complete paralysis and death from respiratory failure in absence of ventilatory support. After 12 hours, regardless of severity, victims start to recover gradually and are without any residual symptoms within a few days (Bower et al, 1981, ILO 1984, Halstead 1988).

Other symptoms include headache, dizziness, nausea, vomiting, rapid pain, and anuria. There is no loss of consciousness and the reflexes are unaltered except maybe pupillary size and sight may be temporarily lost.

The overall mortality (case fatality rate) was about 8.5% -9.5% in two large series (Meyer 1953, Ayres and Cullum 1978). However, the Guatemalan 1987 outbreak on Pacific coast had a case fatality rate of 14%

I'm not really clear


on exactly which culprit they are talking about. Bacteria related illness can normally be avoided by cooking whereas the dinoflaggelate and diatomaceous blooms produce toxins not neutralized by heat. Jerry see if you can get a scientific name. I think the media is at fault by stating cooking remediates the problem. That to me would be a gamble regardless of the evaluation. Why take chances.

stick to the seaweed, you can't go wrong, they're all edible and they got tons of nutrients.

I spent a whole week on the Olympic peninsula this summer, eating that (along with different kinds of berries, trout and beach peas)

dinoflaggelate and diatomaceous ? These words are too big for me to understand. Diatomaceous might be what I put in my swimming pool filter. Dinoflaggelate sounds like a prehistoric animal pado that comes on after midnight. Bob and Susan can probably understand these words---they live in Mulege and Upland.



If there is no fishing in heaven, I am not going

Bob and Susan . Actually they already do. "Irish Moss" is added to some beer to help precipitate proteins in beer that can result in cloudiness (chill haze)
