CDC is advising that people not eat romaine lettuce after an outbreak of E. coli has been identified. There have been thirty-two people infected with the outbreak strain of Shiga toxin-producing E. coli O157:H7 have been reported from 11 states with thirteen people hospitalized, including one person who developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported. The illnesses are listed with dates ranging from October 8, 2018 to October 31, 2018.
The reason for warning against all romaine lettuce is that the source is not known yet. Until more information is gathered, CDC is taking a precautionary stance.
While this strain is linked to past outbreaks, it is not linked to the recent E.coli outbreak in Yuma AZ, but it is linked to the 2017 E. coli outbreak. "Whole genome sequencing (WGS) results showed that the E. coli O157:H7 strain isolated from ill people in this outbreak is closely related genetically to the E. coli strain isolated from ill people in a 2017 outbreak linked to leafy greens in the United States and to romaine lettuce in Canada. The current outbreak is not related to a recent multistate outbreak of E. coli O157:H7 infections linked to romaine lettuce. People in the spring outbreak were infected with E. coli O157:H7 bacteria with a different DNA fingerprint."
In the 2017 outbreak of the same strain, the source was not definitively found, although it was said to be leafy greens. In that outbreak, CDC and FDA were criticized for not stating it was Romaine lettuce.

Outbreak of E. coli Infections Linked to Romaine Lettuce
Posted November 20, 2018 at 2:30 PM ET
CDC, public health and regulatory officials in several states, Canada, and the U.S. Food and Drug Administration (FDA) are investigating a multistate outbreak of Shiga toxin-producing Escherichia coli O157:H7 (E. coli O157:H7) infections linked to romaine lettuce.
While this strain is linked to past outbreaks, it is not linked to the recent E.coli outbreak in Yuma AZ, but it is linked to the 2017 E. coli outbreak.
