UPDATE: Multistate Outbreak of E. coli O157:H7 Infections Linked to Chopped Romaine Lettuce

What's New?


Case Count Update

    Since the last update on April 25, 2018, 14 more ill people were added to this outbreak.

    As of April 26, 2018, 98 people infected with the outbreak strain of E. coli O157:H7 have been reported from 22 states. A list of the states and the number of cases in each can be found on the Case Count Map page. Illnesses started on dates ranging from March 13, 2018 to April 20, 2018. Ill people range in age from 1 to 88 years, with a median age of 31. Sixty-five percent of ill people are female. Of 87 people with information available, 46 (53%) have been hospitalized, including 10 people who developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported. 

    Illnesses that occurred after April 7, 2018, might not yet be reported due to the time it takes between when a person becomes ill with E. coli and when the illness is reported. This takes an average of two to three weeks.  

    Investigation Update

    Information collected to date indicates that chopped romaine lettuce from the Yuma, Arizona growing region could be contaminated with E. coli O157:H7 and could make people sick. No common grower, supplier, distributor, or brand has been identified at this time. Read CDC’s advice to consumers, restaurants, and retailers.

    This investigation is ongoing, including work to identify the source of the romaine lettuce. CDC will provide more information as it becomes available.
