2019 Multistate Romaine Lettuce E. coli Outbreak
Marler Clark investigated a multistate E. coli outbreak linked to romaine lettuce in Autumn 2019.
In Autumn 2019, the U.S. Food and Drug Administration shared news of a recent E. coli O157:H7 outbreak, involving 23 illnesses, that was likely associated with romaine lettuce. No deaths were reported. The 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 communicated 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 did 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 was 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.
