here is a letter I got from an LFS owner in my area. All Zoa are toxic so take precautions when cutting them.
I would just like to share with you a amazing incident that I just experienced last night. I just set up a holding tank in my garage 8'long x 6'wide x1'high. Over the long weekend I had recieved some pathyoa zoanthids ( over 2,000 heads on ten large pieces of liverock ) from a client of mine. My employees put all of the liverock covered with them into my holding tank and left. I was out of town for three days, when I returned home I went to the garage to look at the specimens I was shocked to see how many polyps had grown covering all of the client's liverock. I noticed that my chiller had was on and the garage was extremely hot because I have not installed a vent in my garage yet.
Here's the cool part.... as I was cleaning my garage for about an hour, when my eyes started to burn and my nose started to run. In my mind, I thought that all of the dust that I was kicking up caused a allergy type response. Then, I had a funny taste in my mouth of metal. Then, I already had a idea that I had just become posioned with a neurotoxin. About 10mins later I had a headache, muscle achyness, my running nose became 10 times worse, my eyes were so tearful that I couldn't see. My wife and dog were in the garage with me for about 30minutes and suddenly she too had the same symptoms. An hour later my dog became sluggish and had a hard time breathing. I have to perform minor chest compressions to create a exhaul respiratory response to assist in her breathing.
So, what had happened was when the palythoa colonies was introduced in to my holding tank they released Neurotoxins in to the water. Then as the chiller raised the temperature in the garage. This caused steam from the tank and as I was cleaning my garage I was inhaling all of the neurotoxins come from the tank water. I am guessing that with the high concentrations of neurotoxin for all of the palythoa. That they became airborne and I was inhaling it for more than 1hour.
Wow! What a experience!!! I would never imagine neurotoxin posioning could be effective through air. This is why I am sharing this experience with my clients and friends. I am very lucky that none of us became seriously ill.
All species of Palythoa, and most related zoanthids including the Protopalythoa species, produce a chemical called PALYTOXIN in their mucus and gonads. Indigenous Pacific tribes used this neuromuscular agent to tip spears in order to paralyze prey animals and enemies. This is a potent toxin and can be deadly to humans. It is important to wear hand protection when touching these animals, especially if the handler has any breaks in his or her skin.
While many aquarists routinely handle corals, including zoanthids, without incident, it is still a very good idea to maintain a safe health protocol when working with these animals. Wearing gloves or making sure that no breaks in the skin are present is a start. (Aquarium Corals Selection, Husbandry, and Natural History, Eric H. Borneman pgs 182)
