I agree that quarantine is important, but no one is going to quarantine their snakes for years. It would be almost impossible to move anything out of quarantine because you need to reset the quarantine clock when you add a new snake to quarantine. So the fact that IBD can take years to manifest is moot in this argument. Things like internal parasites would be a much better quarantine argument, or something else that can take weeks to present itself. Most people quarantine for 60-90 days, not years.
