This is the official ruling.

All of the cards that have mixed with the stub, and are not 100% decernable as a players mucked hand, and/or burned cards, etc.. Are to be re-shuffled and the final burn and river is to be laid out.

Bluff Magazine interview with TJ Cloutier:

Bluff Magazine: In all your years, what’s the strangest thing you’ve seen at the poker table?

TJ Cloutier: Worst beat ever: I was playing in a live game years ago at the Bicycle club with Al Krux. He’s a good player, but he was running bad that day. He had something like $490, and he moved all in. The guy two seats to his left was getting a massage. He held up his hand showed it to the masseuse and mucked it. It got around to me on the button with two tens and I called. The dealer made a mistake; he didn’t see I’d called and he dropped the deck on the muck, so they had to reshuffle it all. When they reshuffled, the flop came K-10-4. Al had two kings in the hole, and the turn came another ten – so I made four tens to beat him. But that’s not the kicker. The kicker was that the guy that had held his hand up to the masseuse had had the other two tens. That’s the worst beat in history. You can’t get a worse beat than that.
