Aaron E. Carroll, The New York Times:
Perhaps no one in the United States has spent more time investigating the occurrence of bacteria on public surfaces than Charles Gerba. He’s a professor of microbiology and environmental sciences at the University of Arizona, and he has published many papers on the subject.
In 1998, he and his colleagues investigated how well cleaning products could reduce coliform bacteria counts on household surfaces. As part of that research, they measured various locations in the house before any cleaning.
They found that the kitchen floor was likely to harbor, on average, about three colonies per square inch of coliform bacteria (2.75 to be exact). So there are some. But here’s the thing — that’s cleaner than both the refrigerator handle (5.37 colonies per square inch) and the kitchen counter (5.75 colonies per square inch).
