Source of Romaine Lettuce E. coli Outbreak Identified; Investigation Continues

Health experts say they now know where the romaine lettuce linked to an E. coli outbreak was based.

The Centers for Disease Control and Prevention says the E. coli strain has been traced to a reservoir on a farm in Santa Barbara County, California.

Despite the announcement, other possible sources for the outbreak are still being investigated. 

For now, the CDC advises people not to eat romaine lettuce grown in California’s Monterey, San Benito and Santa Barbara counties until the investigation is complete.

However, properly labeled romaine grown outside those counties and harvested after Nov. 23 is O.K. to eat, along with romaine grown in greenhouses or hydroponically.
