"Every day, parents blithely drop their toddlers into the baskets of shopping carts, never giving a moment’s thought to who might have had their hands on the handle last. Preliminary results from a new study show that may be a mistake.Researchers from the University of Arizona swabbed shopping cart handles in four states looking for bacterial contamination. Of the 85 carts examined, 72 percent turned out to have a marker for fecal bacteria.
The researchers took a closer look at the samples from 36 carts and discovered Escherichia coli, more commonly known as E. coli , on 50 percent of them — along with a host of other types of bacteria.
The study’s results may explain earlier research that found that kids who rode in shopping carts were more likely than others to develop infections caused by bacteria such as salmonella and campylobacter, Gerba said.“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.”
Shopping cart handles aren’t the only thing you need to worry about when you go to the local supermarket, Gerba added. In other research, he’s found that reusable shopping bags that aren’t regularly washed turn into bacterial swamps. “It’s like wearing the same underwear every day,” Gerba said."I alway try to use disinfecting wipes or a shopping cart cover and diligently wash my both cart covers and my reusable bags.
