What's New?

  • Romaine lettuce tied to a recent outbreak of E. coli is likely no longer on store shelves or in restaurants, the Centers for Disease Control and Prevention said today (May 16).
  • That means that the agency is no longer advising consumers to avoid buying romaine lettuce in connection with the outbreak.

Historical Features:

  • Twenty-three more ill people from 13 states were added to this investigation since the last update on May 9, 2018.
  • Three more states have reported ill people: Iowa, Nebraska, and Oregon.

CDC is updating its advice to consumers. According to the U.S. Food and Drug Administration, the last shipments of romaine lettuce from the Yuma growing region were harvested on April 16, 2018 and the harvest season is over. It is unlikely that any romaine lettuce from the Yuma growing region is still available in stores or restaurants due to its 21-day shelf life. It takes two to three weeks between when a person becomes ill with E. coli and when the illness is reported to CDC. The most recent illnesses reported to CDC started when romaine lettuce from the Yuma growing region was likely still available in stores, restaurants, and in peoples’ homes.

Information collected to date indicates that romaine lettuce from the Yuma growing region could have been contaminated with Shiga toxin-producing E. coli O157:H7 and made people sick.
