The United States has been experiencing a series of E coli outbreaks in products ranging from onions to, most recently, ground beef. More than 167,000 pounds (75.75 tonnes) of ground beef have been recalled after people fell sick from eating hamburgers at restaurants with a common meat supplier.

Wolverine Packing Co., a Detroit, Michigan meat manufacturer, voluntarily recalled ground beef nationwide after being connected to a small E. coli outbreak. The USDA listed the recall as class I for the highest risk of health consequences and warned the meat may still be in restaurants.
