To be fair, it might have been first identified there because there was a lab equipped to isolate it, but I don't really know. I mean, China has had a problem with things like fake eggs, so who knows?

Its DNA seems to have been sequenced and made available online. If it's anything that has obviously been tampered with by a lab, I expect someone to point that out sooner or later. That said, I have no idea what sort of thing could be detected in the first place.
