E. coli found on 50 percent of shopping carts

Researchers from the University of Arizona swabbed shopping cart handles in four states looking for bacterial contamination. 72 percent turned out to have a marker for fecal bacteria. Upon closer inspection of the samples, researchers discovered Escherichia coli (E. coli), on 50 percent of them.

“That’s more than you find in a supermarket’s restroom,” said Charles Gerba, the lead researcher on the study and a professor of microbiology at the University of Arizona. “That’s because they use disinfecting cleaners in the restrooms. Nobody routinely cleans and disinfects shopping carts.”
