I just ran across this and wanted you to hear it from me. I’ve wondered about this since I started using reusable shopping bags: Yes, you want to wash them, at least once in a while.
Random tests of reusable shopping bags found they can serve as a breeding ground for bacteria — enough to make you sick. The study conducted by the University of Arizona, found that 97 percent of those interviewed have never washed their bags.
The report suggested separating uncooked food from dry goods. It said don’t use the bags for anything else, and don’t store them in the trunk, which can grow bacteria.
I violate these suggestions pretty much every day. It would have been nice for them to tell us how to wash them. I guess throw them in the washer on cold and gentle, and let them air dry? I’ll give it a try.
