A study of shopping carts has Americans scared, but a Cal Poly professor says everyone should chill out.
On Thursday, the University of Arizona released a Clorox-sponsored study that found 72 percent of shopping carts had fecal matter on them. It sounded icky, of course, but is it dangerous? We asked California Polytechnic State University professor of biology Pat Fidopiastis his thoughts on the research. What he had to say should put you at ease. In short, there are poop germs around you all the time, but, if you do a few simple things, you're probably going to be just fine.
