A total of nine people infected with the outbreak strain of STEC O157 have been reported from two states. The number of ill people identified in each state is as follows: Minnesota (7) and Wisconsin (2).
Collaborative investigative efforts of state, local, and federal public health and regulatory officials indicate that alfalfa sprouts produced by Jack & The Green Sprouts of River Falls, Wisconsin are a likely source of this outbreak. This outbreak does not appear to be related to the ongoing multistate outbreak of Salmonella Muenchen infections linked to alfalfa sprouts produced by Sweetwater Farms of Inman, Kansas.
State and local health and regulatory officials performed traceback investigations from seven different locations where ill people ate or bought alfalfa sprouts. These investigations indicated that Jack & The Green Sprouts supplied alfalfa sprouts to all seven locations.
The information available to date indicates that alfalfa sprouts produced by Jack & The Green Sprouts may be contaminated with STEC O157 and are not safe to eat. On February 24, 2016, the Minnesota Department of Health issued a press release warning consumers not to eat these products. CDC recommends that consumers do not eat and restaurants and other retailers do not sell or serve alfalfa sprouts produced by Jack & The Green Sprouts at this time.
