A total of 29 individuals infected with the outbreak strain of E. coli O26 have been reported from 11 states. The 4 new cases have been reported from Michigan, Pennsylvania, Washington, and West Virginia. Of the 27 ill persons with available information, 23 (85%) reported consuming sprouts at Jimmy John’s restaurants in the 7 days preceding illness. Among 29 ill persons, illness onset dates ranged from December 25, 2011 to March 3, 2012. Ill persons range in age from 9 years to 57 years old, with a median age of 26 years. Eighty-nine percent of ill persons are female. Among the 29 ill persons, 7 (24%) were hospitalized. None have developed HUS, and no deaths have been reported.
Preliminary traceback information has identified a common lot of clover seeds used to grow clover sprouts served at Jimmy John’s restaurant locations where ill persons ate. FDA and states conducted a traceback that identified two separate sprouting facilities; both used the same lot of seed to grow clover sprouts served at these Jimmy John’s restaurant locations. On February 10, 2012, the seed supplier initiated notification of sprouting facilities that received this lot of clover seed to stop using it. Investigations are ongoing to identify other locations that may have sold clover sprouts grown from this seed lot.

Multistate Outbreak, Tiny Greens Organic Farm, Jimmy John’s Restaurants Alfalfa Sprouts Salmonella Outbreak 2010
140 Sickened – On December 17, the Illinois Department of Health announced that an investigation was underway into an outbreak of Salmonella, serotype I4,,12:i:-. Many of the Illinois cases had eaten alfalfa sprouts at various Jimmy John’s restaurants in the Illinois counties of: Adams, Champaign, Cook, DuPage, Kankakee, Macon, McHenry, McLean, Peoria, and Will counties. The sprouts were suspected to be the cause of the illnesses. On December 21, Jimmy John Liautaud, the owner of the franchised restaurant chain, requested that all franchisees remove sprouts from the menu as a “precautionary” measure. On December 23, the Centers for Disease Control revealed that outbreak cases had been detected in other states and that the outbreak was linked with eating alfalfa sprouts while at a nationwide sandwich chain. On December 26, preliminary results of the investigation indicated a link to eating Tiny Greens’ Alfalfa Sprouts at Jimmy John’s restaurant outlets. The FDA subsequently advised consumers and restaurants to avoid Tiny Greens Brand Alfalfa Sprouts and Spicy Sprouts produced by Tiny Greens Organic Farm of Urbana, Illinois. The Spicy Sprouts contained alfalfa, radish and clover sprouts. On January 14, 2011, it was revealed that the FDA had isolated Salmonella serotype I4,,12:i:- from a water runoff sample collected from Tiny Greens Organic Farm; the Salmonella isolated was indistinguishable from the outbreak strain. The several FDA inspections of the sprout growing facility revealed factors that likely led to contamination of the sprouts.
CW Sprouts, Inc., SunSprout Sprouts, “restaurant chain (Chain A),” a.k.a. Jimmy Johns Salmonella Outbreak 2009
256 Sickened – In February, Nebraska Department of Health and Human Services officials identified six isolates of Salmonella Saintpaul. Although this is a common strain of Salmonella, during 2008, only three cases had been detected in Nebraska and only four subtypes of this outbreak strain had been identified in 2008 in the entire USA. As additional reports were made, a case control study was conducted; alfalfa sprout consumption was found to be significantly related to illness. The initial tracebacks of the sprouts indicated that although the sprouts had been distributed by various companies, the sprouts from the first cases originated from the same sprouting facility in Omaha, Nebraska. Forty-two of the illnesses beginning on March 15 were attributed to sprout growing facilities in other states; these facilities had obtained seed from the same seed producer, Caudill Seed Company of Kentucky. The implicated seeds had been sold in many states. On April 26, the FDA and CDC recommended that consumers not eat raw alfalfa sprouts, including sprout blends containing alfalfa sprouts. In May, FDA alerted sprout growers and retailers that a seed supplier, Caudill Seed Company of Kentucky, was withdrawing all alfalfa seeds with a specific three-digit prefix. Many of the illnesses occurred at “restaurant chain (Chain A).”
