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

What's New?


Case Count Update

Since the last update on May 2, 2018, 28 more ill people from 12 states were added to this outbreak. Four more states have reported ill people: Florida, Minnesota, North Dakota, and Texas.

As of May 8, 2018, 149 people infected with the outbreak strain of E. coli O157:H7 have been reported from 29 states. A complete 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 25, 2018. Ill people range in age from 1 to 88 years, with a median age of 30. Sixty-five percent of ill people are female. Of 129 people with information available, 64 (50%) have been hospitalized, including 17 people who developed hemolytic uremic syndrome, a type of kidney failure. One death was reported from California.

Illnesses that occurred after April 17, 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.

Advice to Clinicians

Antibiotics are not recommended for patients with suspected E. coli O157 infections until diagnostic testing can be performed and E. coli O157 infection is ruled out. Some studies have shown that administering antibiotics to patients with E. coli O157 infections might increase their risk of developing hemolytic uremic syndrome (a type of kidney failure), and a benefit of treatment has not been clearly demonstrated.
