WASHINGTON (AP) -- Lettuce grown in Yuma, Ariz., may be the source of a widespread E. coli outbreak in romaine lettuce that has sickened at least 19 people and prompted a recall in 23 states.
Federal investigators are looking at a farm in Yuma as a possible source for the outbreak, according to the distributor who sold the lettuce.
Freshway Foods of Sidney, Ohio, said Thursday it recalled lettuce sold in 23 states and the District of Columbia because of a possible link to an E. coli outbreak that has sickened at least 19 people -- three with life-threatening illness.
College students at the University of Michigan in Ann Arbor, Ohio State in Columbus and Daemen College in Amherst, N.Y., are among those who were affected by the outbreak, according to health departments in those states. The health officials said most of the victims were sickened in April and have already recovered.
Vice president Devon Beer said Freshway Foods worked with the Food and Drug Administration to trace the contaminated lettuce to a Yuma grower, whom he would not identify.
The recall only applies to romaine lettuce with "best if used by" date before or on May 12, when Freshway Foods stopped buying its romaine from Yuma, Beer said.
Officials in Arizona also confirmed the investigation. Laura Oxley, a spokeswoman for Arizona's agriculture and health departments, said federal officials contacted them and told them they suspected the source of the E. coli outbreak was lettuce grown in the state. She said there were no additional shipments to stop because the winter lettuce season has mostly ended for the year.
The Yuma area is the source of much of the nation's winter lettuce crop, but farmers switch to other crops at the end of winter.
Freshway Foods said Thursday it was recalling romaine lettuce sold under the Freshway and Imperial Sysco brands. No contamination was found at the company's processing plant, according to the FDA. New York state's Public Health Laboratory discovered the contamination in a bag of Freshway Foods shredded romaine lettuce on Wednesday after local authorities had been investigating an outbreak for several weeks.
The most common strain of E. coli found in U.S. patients is E. coli O157. The CDC said the strain linked to the lettuce, E. coli 0145, is more difficult to identify and may go unreported.
E. coli infection can cause mild diarrhea or more severe complications, including kidney damage. The three patients with life-threatening symptoms were diagnosed with hemolytic uremic syndrome, which can cause bleeding in the brain or kidneys.
It was not immediately clear why students on college campuses were sickened. Freshway Foods said the lettuce was sold to wholesalers, food service outlets, in-store salad bars and delis. The recall also affects "grab and go" salads sold at Kroger, Giant Eagle, Ingles Markets and Marsh grocery stores. Bagged lettuce at the grocery store is not involved in the recall so far.
Most of the recalled lettuce was sold in states east of the Mississippi River. It was sold in Alabama, Connecticut, the District of Columbia, Florida, Georgia, Illinois, Indiana, Kansas, Kentucky, Maryland, Massachusetts, Michigan, Missouri, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, West Virginia and Wisconsin.
