Re: eating raw????
You can eat most anything raw. Cooking kills parasites in the animals flesh as well as any microbes on the surface or that which might be left over from preparing.
Your digestive system & immune system can handle some parasites and bacteria. Or not.
Some species are more prone to parasites that are better adapted to withstanding the human digestive & immune system. Others less so.
Eating raw is a roll of the dice each and every time.
I've eaten raw clams straight out of the bay. Are they any "cleaner" than a blues flesh? I doubt it!
Personally, I'd not risk eating raw anymore. What's the upside as opposed to the potential downside?
Then again, I may change my mind on the in the "heat of the moment" (cough*afterafewbeers*ahem)
