From the department of no good deed going unpunished, The New York Times reported Sunday that some reusable shopping bags could be contaminating your food with lead. But MoJo reader Barb wrote in with a different health concern about the eco-bags:

“I just got accosted by a man in the grocery store who insisted that my reusable bags were ‘spreading E. coli‘…He seemed to think that I was bringing it into the store and putting people at risk by doing so.”

This piqued my curiosity: Can bags breed bacteria? And if so, how likely is it that shoppers with tainted bags are spreading the bugs around their local markets?

I called Craig Hedberg, a professor in the University of Minnesota’s Division of Environmental Health Sciences. Hedberg told me that the most likely bacteria scenario for reusable bags would likely involve juices leaking from meat, which could, in theory, breed Salmonella or Listeria, or less likely, E. coli or Campylobacter, which could contaminate your veggies on your next trip to the supermarket. “But you have to look at what the likelihood of that is,” says Hedberg. “Probably your meat is going to be in a container, not leaking.” The risk of bacteria that originates on fruits and veggies, he says, is “very low,” as is the risk of a shopper unknowingly spreading bacteria by reaching into a contaminated bag and touching food. “Theoretically this could happen, but it’s not likely.”

That said, you can practically eliminate the risk of bag-borne bacteria by washing your bags after each use. Always wash your produce. Keeping separate bags for meat and produce (like cutting boards) is another good idea. Washing your hands after you go to the grocery store probably wouldn’t hurt, either.

IT'S NOT THAT WE'RE SCREWED WITHOUT TRUMP:

"It's that we're screwed with or without him if we can't show the public that what we do matters for the long term," writes Mother Jones CEO Monika Bauerlein as she kicks off our drive to raise $350,000 in donations from readers by July 17.

This is a big one for us. It's our first time asking for an outpouring of support since screams of FAKE NEWS and so much of what Trump stood for made everything we do so visceral. Like most newsrooms, we face incredibly hard budget realities, and it's unnerving needing to raise big money when traffic is down.

So, as we ask you to consider supporting our team's journalism, we thought we'd slow down and check in about where Mother Jones is and where we're going after the chaotic last several years. This comparatively slow moment is also an urgent one for Mother Jones: You can read more in "Slow News Is Good News," and if you're able to, please support our team's hard-hitting journalism and help us reach our big $350,000 goal with a donation today.
