The USDA is alerting shoppers that certain packages of ground beef sold at Whole Foods could be contaminated with E. coli—a bacteria that can cause serious illness. If you’ve recently bought ground beef from Whole Foods, you might want to double-check the labels or hold off on cooking it until more details come out.

Editor’s Note: Nobody wants a side of food poisoning with their dinner. This warning is a heads-up for anyone who shopped at Whole Foods recently, especially since E. coli infections can be nasty. It’s also a reminder that even high-end grocery stores aren’t immune to food safety issues. Stay tuned for recalls or updates.
