According to the CDC, four confirmed cases and one suspect case of STEC O104:H4 infections have been identified. Of these five cases, four recently traveled to Hamburg, Germany, where they were likely exposed. The bacterial isolates from the three HUS cases reported in Massachusetts, Michigan, and Wisconsin and one case with Shiga toxin-positive diarrheal illness in Michigan have been confirmed as matching the outbreak strain. The Michigan case with Shiga toxin-positive diarrheal illness did not travel to Germany, but is a close contact of the Michigan case with HUS. Their diarrheal illness developed later and was likely acquired through contact with the HUS case.

The outbreak has been traced to an organic sprouter local to Hamburg.  The sprouts were sold directly and to restaurants and hotels in the Hamburg area.
