Granted, I don't know this industry and my opinion is based off of vet assist work with dogs, cats, etc. Parasites are parasites though, so I just think that'd be one thing to definitely worry about.
So are you stating your a vet tech? I actually work in a vets office while im in college for pre-vet, granted im only a freshman, but have already assisted in surgeries, administered medications, along with assisting in procedures every day.

I will tell you now a parasite is not a parasite. Parasites are extremely host specific organisms. A very small percentage of parasites, diseases, viruses, etc. are actually zoonotic, meaning they are able to be transfered to humans. So if your worried about contracting a parasite yourself from the imports than the chances are nil to none. That being said, internal parasites are treated on a regular basis, and the herps you have in your collection now most likely have some parasites residing in them at the moment, but they are not able to thrive because of the immune system.

Honestly there is not much to worry about with the parasites. Yes some are actually able to thrive in humans, but most are not. Parasites are very specialized organisms.
