Oh I'm sure its far worse than that. It hasn't been really mentioned by anyone what the DNA is from exactly, but I would bet its non-human. Non-human DNA Plasmids are used in production of these things (and other biologics), but there is good reason to believe this is far more sinister than mere contamination.
