2010 Multistate Outbreak of E. Coli O145 Linked to Freshway Foods Romaine Lettuce

Cases of a genetically-identical strain of E. coli O145 were identified in the states of Michigan, Ohio, Tennessee, Pennsylvania, and New York. Illness onsets occurred between April 10 and 26. Several of the cases were students at Ohio State University, the University of Michigan, and Daemen College (Buffalo, New York). Several of the ill in Ann Arbor, Michigan, had eaten at a common restaurant. At least four students in the Wappinger Central School District, in New York State, were also involved in the outbreak. Shredded lettuce served in the school district tested positive for E. coli bacteria. Romaine lettuce was named as the vehicle for this outbreak, on May 6, after the same strain of E. coli O145 was found in a Freshway Foods romaine lettuce sample in New York state. Freshway Foods issued a voluntary recall of various bagged lettuces. The traceback investigation suggested that the source of the lettuce was a farm in Yuma, Arizona. In Ohio, a second, independent strain, of pathogenic E. coli was isolated from Freshway Foods bagged, shredded, romaine lettuce, E. coli O143:H34. This strain was not linked to any known food-borne illness. The isolation of the second strain of E. coli led to an additional recall of lettuce. Andrew Smith Company, of California, launched a recall of lettuce sold to Vaughan Foods and to an unidentified third firm in Massachusetts. Vaughan Foods of Moore, Oklahoma, received romaine lettuce harvested from the same farm in Yuma, Arizona; the romaine lettuce had been distributed to restaurants and food service facilities.
