The U.S. Centers for Disease Control and Prevention (CDC) on Friday directed Americans to throw away all romaine that could have been grown near Yuma, Arizona, which is believed to be the source of E. coli contamination on the lettuce. The CDC originally warned against pre-chopped romaine only, but the caution has been expanded to include hearts of romaine and full heads of the lettuce.
Some 53 people in 16 states have been affected by the outbreak. While five have suffered kidney failure from the bacteria, no deaths have been reported so far. Read the CDC's full report on the outbreak here. Bonnie Kristian
