"The strain of E. coli causing the current outbreak in romaine lettuce has been found in a reservoir on a farm in Santa Barbara County, California, the US Food and Drug Administration and Centers for Disease Control and Prevention announced Thursday.
The agencies are continuing to investigate other possible sources, and the CDC still advises consumers not to eat romaine lettuce grown in California's Monterey, San Benito and Santa Barbara counties until investigations are complete.
'We cannot say how many cases are linked to this specific farm at this time,' Ian Williams, chief of the CDC's outbreak response and prevention branch, said at a press briefing. 'We have to do additional work at this farm and other farms that are being identified from our investigation.'"
