For us, yes. If we get in a batch and something appears in one (or more), we treat the batch and they remain in quarantine until the full treatment is completed, and we're satisfied that the issue has been addressed.
It wouldn't be smart of us to then put potentially infected/infested fish in with others that aren't - ie from earlier arrivals that also went through the same protocol and are now in the sell system. It only takes one, to infect/infest many.
Again, I can only speak for our own procedures.
Nothing is foolproof - and anyone who says that it is, is misinformed, IMO. Protocols at the retail level mitigate the risk, but at the hobbyist level, it's still prudent for individuals to quarantine their new acquisitions. Unfortunately, most still don't, and those that do, the majority, in my experience, only start doing it after a disaster. Most folks don't want to take the time, or the investment, to take a simple precaution. Some folks are lucky and never have a problem. Others, not so much.
In my opinion, it's just common sense, as a hobbyist, to take that extra step to attempt to prevent, a preventable problem.
