…We wouldn’t!
To be honest though, the study didn’t really turn up anything especially damning about reusable bags (but we’re sure its sponsors would have liked it to!) Funded by the Canadian Plastics Industry, the research basically found that if a small amount of water sits at the bottom of a folded reusable bag for an extended amount of time, certain types of bacteria could develop, some of which could be harmful if they were to come in direct contact with food.
In teenager speak, “Um… no duh! Did it really take a specially-funded scientific study to discover this?”
In short, to be super safe, clean your reusable bags from time-to-time! Just like you would your yoga mat – another surface which could potentially accumulate harmful bacteria if moisture remains trapped inside a rolled-up mat for a certain length of time. Hey, maybe someone should sponsor a study about the scary risks of yoga mats! Hello, Pilates Mat Industry?
