Not that there aren't shenanigans to root out on the customer end. When one dissatisfied KFC customer took to Facebook to complain that he'd been served a salty, crispy portion of Kentucky fried rat, the man got himself a lawyer and the rat was handed over for independent lab testing. Those tests confirmed that it was in fact just chicken with a "tail" made of breading. No lawsuit for you, sir!
As testing becomes cheaper/easier, we're going to see all kinds of petty shenanigans resolved this way. Did you know there's a company called PooPrints out there that will genetically test dogshit to find out who's not been cleaning up after their pet? And then they'll drive to the dog owner's house and throw the feces at their front door? (Note: I am now told that they do not do this second part.)
The way it works is that homeowner's associations and building management require pet owners to submit a sample so that it can be matched in the event of an unscooped turd later. And hey, that means less shit on your shoes and fewer wannabe Tyler Durdens befouling our food. Great! There is no possible way this can ever be abused! Yes, I can't wait to get a plumber's bill from a convenience store after a DNA test proved I was the one who clogged their toilet last month.
