FDA Investigating Multistate Outbreak of E. coli O157:H7 Infections Likely Linked to Romaine Lettuce
The FDA, along with CDC, state and local agencies, is investigating a multistate outbreak of E. coli O157:H7 illnesses likely linked to romaine lettuce. The Public Health Agency of Canada (PHAC) and Canadian Food Inspection Agency, are also coordinating with U.S. agencies as they investigate a similar outbreak in Canada.
Genetic analysis of the E. coli O157:H7 strains tested to date from patients in this current outbreak are similar to strains of E. coli O157:H7 associated with a previous outbreak from the Fall of 2017 that also affected consumers in both Canada and the U.S. The 2017 outbreak of E. coli O157:H7 was associated with leafy greens in the U.S. and romaine in Canada. This year, romaine lettuce is the suspected vehicle for both the U.S. and Canadian outbreaks. There is no genetic link between the current outbreak and the E.coli O157:H7 outbreak linked to romaine that occurred in the Spring of 2018.
