Food Safety Report: Lucky Charms, Walmart Supercenter, East Green Bay Avenue, Saukville, WI, USA 3 years ago • details 7 Comments Comment I've had over a week of diarrhea while 8w pregnant. I ate an entire box of Lucky Charms last week. I tested negative for e.coli, salmonella and more. So what's the bacteria? 06/25 update: Symptoms are better but stools are still a little loose. I ate the Lucky Charms 6/14-6/18.
