The number of people who have fallen ill from E. coli-tainted romaine lettuce grown in the Yuma, Arizona, region has risen to 98, the CDC announced on April 27.
More than half the victims became ill enough to be hospitalized and the CDC said consumers should not eat any romaine or romaine-containing products unless they know that the lettuce did not originate from the Yuma region.
The strain of Escherichia coli seen in the outbreak is known to be particularly severe.
Ten of the 46 people hospitalized have hemolytic uremic syndrome. There have been no deaths in the outbreak, which began on April 20th and has now spread to 22 states, most recently Mississippi, Tennessee, and Wisconsin.
