Deadly microbes like salmonella and E. coli can lurk on the surface of spinach, lettuce and other fresh foods. But many more benign microbes also flourish there, living lives of quiet obscurity, much like the tiny Whos in Dr. Seuss' Whoville. Until now.

It turns out the invisible communities living on our food vary greatly, depending on the type and whether it's conventional or organic.
