On February 15, 2012, the Centers for Disease Control first announced an ongoing investigation into illnesses linked to the consumption of raw clover sprouts consumed at Jimmy John's Restaurants in several states. The illnesses were caused by E. coli O26. By April 3, 29 cases were known. Illness onsets ranged from December 25, 2011 to March 3, 2012. Ill persons ranged in age from 9 years to 57 years old, with a median age of 26 years old. Eighty nine percent of the cases were female. No cases developed hemolytic uremic syndrome(HUS), however 7 cases were hospitalized. No deaths were reported. The FDA and the states conducted a traceback that identified two separate sprouting facilities; both used the same lot of seed to grow clover sprouts served at Jimmy John's restaurant locations.

On February 17, Jimmy John's Restaurants announced that it was pulling sprouts from its restaurant menus.
