I got exposed to palytoxin by washing a frag rack with some on it under hot water. Some steam must have gotten some it in. I noticed a slight irritation in my throat. Stopped immediately (threw the rack out) - did what I could to rinse my mouth, etc... A few hours later I had labored breathing, I got chills, low oxygen levels in the blood, etc... I was put on oxygen and it cleared up. The exposure must have been minor sense I couldn't have inhaled that much vapor and it was only for a few seconds - but it still had a bad affect.
If you were exposed you would know by now I agree with the other comments in the thread about cuts and other infections though - especially those darn tube worms!!!!
