Raw and lightly cooked sprouts are a known source of foodborne illness. We recommend that consumers, restaurants, and other retailers always follow food safety practices to avoid illness from eating sprouts.Generally, it is recommended that children, the elderly, pregnant women, and persons with weakened immune systems should avoid eating raw sprouts of any kind.


FDA, along with CDC and state and local partners, investigated an outbreak of 51 illnesses caused by E. coli O103 in Florida, Idaho, Iowa, Illinois, Missouri, New York, Texas, Utah, Virginia, and Wyoming linked to clover sprouts.

FDA’s investigation is now complete, and CDC has declared this outbreak over.

The FDA’s analysis of a sample of Chicago Indoor Garden’s sprouts identified the presence of E. coli O103. Whole Genome Sequencing of this bacteria showed that it matches the current outbreak strain. The sample also matches the outbreak strain from the November-December 2019 outbreak in Iowa, which was associated with sprouts from various Jimmy John’s restaurants.
