Collaborative investigative efforts of local, state, and federal public health and regulatory agencies have linked this outbreak to consumption of Tiny Greens Organic Farm’s Alfalfa Sprouts and Spicy Sprouts. The sprouts were distributed to Illinois, Indiana, Iowa, and Missouri, and may also have been distributed to other Midwestern states. Approximately half of the illnesses occurred in Illinois, where many of the ill individuals ate sandwiches containing sprouts at various Jimmy John’s outlets. Jimmy John’s restaurants have voluntarily suspended serving sprouts at their Illinois franchise locations.
