A second outbreak linked to alfalfa sprouts is under investigation by state and federal health officials after infecting nine people in Minnesota and Wisconsin with a strain of Shiga toxin-producing Escherichia coli O157. According to CDC, two people have been hospitalized.
Investigators say the source of the outbreak is likely tied to alfalfa sprouts produced by Wisconsin-based Jack & The Green Sprouts. All of the infected people interviewed reported eating or possibly eating sprouts in the week before they became ill.
Shortly before this outbreak began, CDC and other health officials reported another multistate outbreak of foodborne illnesses traced by to alfalfa sprouts. In this case, the sprouts were reportedly contaminated with salmonella. To date, 13 people in four states have been infected.
