I'm positive of it. As far as the juicers go, I've seen the oranges wet in baskets that appear to have been at least rinsed, as well as straight out of the box. All fruit imported into the US has been thoroughly washed at the packing house. USDA regs. Not sure about domestic oranges, and of course they could be contaminated somehow in transit. I would prefer that they rinsed off the orange that fell on the floor, but it certainly wouldn't keep me from drinking the juice, or make me go out of my way to report it.
