the risk of spreading this is very high..often the best measure is to eliminate the stock, sterilize the equiptment and start over.
I would soak the wood in a bleach solution for some time. then soak in clean water. chlorine is actually not very stable and will dissipate over time.
:iagree: Soak that wood thoroughly for a while in the bleach solution. It certainly wouldn't hurt after that to boil it if you could. Rinse well repeatedly in dechlor, then I'd let it dry out thouroughly before I'd use it again. Better to be overcautious and not in a hurry than go through this again.
