Ultraviolet light zaps superbugs at UPMC hospitals

[Bubba Gamps]

Very interesting.  UV light has been used for some time in water treatment systems to kill bacteria.  It has been proven that UV rays in sunlight kill viruses, as well.  I don't think it's a stretch to imagine that retailers will use UV light to disinfect their stores in the very near future.   As the technology advances, the cost of units will decrease.
