Following the reddit discussion I learned just about everything has poo on it, even somebody's toothbrush, and every other public touchscreen would be similar affected. Wash your hands before eating. The article is largly hyperhole.

"Reminds me of the myth busters episode where they tested toothbrushes in bathrooms to see if airborne poo was getting on them. It was, but they even found trace amounts of fecal matter on fresh toothbrushes straight out of the package."
