Here’s Why the CDC Wants You to Throw Away All Your Romaine Lettuce

All the romaine lettuce in the U.S. is currently unsafe to eat, the Centers for Disease Control and Prevention has said, warning consumers that an E. coli outbreak is linked to the salad staple.

The warning comes after 32 people in 11 states reported E. coli infections. The number of ill people is expected to increase, says Laura Gieraltowski, team lead of the CDC's foodborne outbreak response team.
