You are an idiot! palytoxin is present in almost every zoanthid that has been in a natural ocean within the least 6 months. therefore, if you work at an LFS that gets wild zoos in, they all have paly toxin. Info from CDC and Global Natural Toxin Center
If you are allergic, 5 micro grams can kill you.
I dont believe that there are any long term side affects from palytoxin either. It may trigger other things, but once it is out of your system it is done.
