The dates for reported illnesses ranged from July 12, 2019 to Sept. 8, 2019. CDC began the investigation of the outbreak on Sept. 17, 2019, at which time there were no further reported illnesses.
According to a Washington Post article, both the CDC and FDA "determined that romaine was the likely cause on October 2nd.", however, this was at a point when there had been no additional cases for several weeks.

“Today, we are sharing news of a recent E. coli O157:H7 outbreak that was likely associated with romaine lettuce. We do not believe there is a current or ongoing risk to the public and we are not recommending the public avoid consuming romaine lettuce,” said FDA Deputy Commissioner for Food Policy and Response Frank Yiannas. “However, our investigation, along with previous outbreaks linked to romaine, reinforces the recommendations that we have made to the leafy green industry: producers must continue to review their practices and improve traceability to enhance food safety. We remain committed to improving the safety of leafy greens and know that all levels of government and the supply chain from farm to retail must continue to work together to keep consumers safe.”
Today, the U.S. Food and Drug Administration is sharing news of a recent E. coli O157:H7 outbreak, involving 23 illnesses, that was likely associated with romaine lettuce. No deaths were reported. The active investigation has reached its end and the outbreak appears to be over. The FDA and the U.S. Centers for Disease Control did not identify actionable information for consumers during this investigation. Additionally, when romaine lettuce was identified as the likely source of the outbreak, the available data at the time indicated that the outbreak was not ongoing and romaine lettuce eaten by sick people was past its shelf life and no longer available for sale. The FDA is communicating details about the outbreak at this time to help ensure full awareness by the public and to highlight the ongoing importance of industry actions to help ensure the safety of leafy greens. Federal health officials do not believe there is a current or ongoing risk to public health.
CDC notified the FDA of this illness cluster in mid-September 2019 and the agency promptly initiated a traceback investigation. The FDA, CDC, along with state and local partners, investigated the illnesses associated with the outbreak. A total of 23 people infected with the outbreak strain of E. coli O157:H7 were reported from 12 states: Arizona (3), California (8), Florida (1), Georgia (1), Illinois (2), Maryland (1), North Carolina (1), Nevada (1), New York (1), Oregon (1), Pennsylvania (2) and South Carolina (1). Eleven people were hospitalized and no deaths were reported. Illnesses started on dates ranging from July 12, 2019 to Sept. 8, 2019. No illnesses were reported after CDC began investigating the outbreak on Sept. 17, 2019.
Investigators were sent to visit farms located in California’s central coast region which were identified through the traceback investigation. They collected and tested many environmental samples, and the outbreak strain was not identified. While romaine lettuce is the likely cause of the outbreak, the investigation did not identify a common source or point where contamination occurred. Since the outbreak strain was not detected in samples collected from farms during the traceback investigation, and there have been no new cases since Sept. 8, 2019, the outbreak appears to be over.
The FDA remains committed to improving the safety of leafy greens and traceability from farm to fork.
