Craig...
nope congers dont have a directly infectious bite like the morays, but they can still do damage if they get hold of a finger, toe or something else

... not that ive actually ever been bitten myself... just going on what ive heard. I still have yet to spear a conger... but i will take the oppertunity if i come across one.
Gimme a PM when you are in this neck of the woods.
