A University of Arizona researcher says you may want to grab one of those disinfectant wipes right before you grab a grocery cart. Professor Charles Gerba, the lead researcher, swabbed the handles of 85 carts in four states for bacterial contamination.
Gerba says 72% of the carts had a positive marker for fecal bacteria. When they examined some of the samples, they found Escherichia coli, also known as E. coli, on half of them.
Researchers say they actually found more fecal bacteria on grocery cart handles than you would typically find in a bathroom, mainly because bathrooms are disinfected more often than shopping carts
