I still don't think we are on the same page...or there is some quackery afoot. Yearly puffer poisonings specifically in Japan are generally rare (in the double digits) and actual deaths from it in the single digits. You mention info that is already common knowledge to those interested in blowfishery & easily googled on the top of the page by the rest...but what gets stuck in my craw is that you're not really making sense. Back on page 2, you claim the poison can render a person brain dead. This is simply untrue. as a paralytic, It will paralyze the respiratory system & that may lead to brain death by way of asphyxiation, but the poison itself does not kill the brain as you claim.
Regulations on it's preparation over there are so stringent that the odds of a quick rush to the hospital are extremely high in a poisoning event and the resulting odds of a respirator hookup and stomach pump also high, thereby significantly lowering toxin exposure and the overall odds of asphyxiation brain damage
If a person survives the poisoning, (which the vast majority do) the toxin is metabolized by the body within a week or so & generally has no significant long term effects on the victim.
Hell, I'm just a layman with an abundance of personal interest and study time on the topic over the years. If you're in med school & have covered it, you really should already know this basic stuff Dude:mellow:
