how dangerous can it be? quite. I have created threads in the past about palytoxins from palythoas and zoanthids, I dont think it can be emphasized enough how dangerous they are, but not only do we have to worry about those (gloves and glasses are a must) but the thousands of bacteria that call our corals home. not just the regular nitrifying etc bacteria but others like vibro, pseudomonas and more. being clean and well protected is always a good idea. hand washing before and after handling ANY coral should be considered mandatory. I also change my shirt after fragging (I remove my shirt then wash my hands) just so any juices that get squirted onto it can not re contaminate me after my hand washing. the dirty shirt goes straight into the washer so no one risks handling it after the fact. people have gotten palytoxin poisoning from used towels. always wash or disposed of anything used in fragging immediately after use, including towels, work surfaces, clothes, and tools. dispose of them properly to ensure pets or children do not contaminate or consume anything left over, a contaminated rubber band is as dangerous to a cat or dog as eating a chunk of palythoa. also as an extra precaution to protect my loved ones I warn my wife that the stuff in the washer is contaminated so she doesnt toutch anything in there. how bad would i feel if my wife got sick just doing the laundry when it was preventable? this may seem a bit drastic to some, especially those that have fragged many times and have yet (note I said yet) to have a problem. but once you get laid up for 2 days with horrific diharreah, you start taking extra precautions. not to ,mention the worse that can happen. I did some fragging this morning and decided to put this out there for people to read in hopes that any first time fraggers ask themselves, how can I be safer, and cleaner.
