Here is a ridiculous article about how reusable grocery bags might kill you. How about we worry about the antibiotic-resistant fecal-contaminated factory farmed animal parts we put into these bags and eventually OUR MOUTHS that are contaminating the bags because they are pumped full of antibiotics to keep them "healthy" as they stand/sit in their own feces all day long and are actually fed USDA approved chicken manure as a protein supplement (just read Everything I Want To Do Is Illegal by Joel Salatin)... and I've got news for you: coliform bacteria are everywhere you care to look. 50% of the bags NOT having coliform is pretty good. (BTW I teach Microbiology) See dumb article below.
