Yeah, a lot of people subscribe to the mentality that "once a captive. always a captive" because of the supposed spread of pathogens and whatnot. I mean, I'm not saying this doesn't happen when a snake is released back into the wild, but I don't think its as detrimental as people believe. I mean, do we need to completely disinfect our clothing and shoes everytime we take a hike through the woods? There's probably a number of things we humans already do whenever we enter nature that are a lot more critical than releasing a short-term captive back into its environment.
