The last of the dangerous Romaine lettuce linked to an extensive E. coli outbreak that killed one person should now be off the shelves. As of May 16, more than 170 people across 32 states had become sick after eating the bacteria-laced lettuce. The lettuce linked to the E.coli contamination was grown in the Yuma, Arizona, region. The last shipments of the infected lettuce were harvested about a month ago.
