The study, conducted by researchers at the University of Arizona, Tucson and Loma Linda University in California, found “large numbers” of bacteria in every reusable bag they tested. E. coli, specifically, was found in about 12 percent of the bags examined.
Washing is so effective, in fact, that the researchers recommend stores be required to put printed instructions on reusable bags “that they be washed between uses or the need to separate raw foods from other food products.”
Libba Letton, a spokesperson for Whole Foods, said the grocery chain does not require such instructions on the reusable bags it sells, and she’s not certain they’re needed.
“It’s not surprising to find out that bags need to be cleaned every once in a while,” Letton said. “Like all reusable items, reusable bags need to undergo some reasonable care to ensure cleanliness.”
