Michigan health officials said today that lettuce or salad greens may be the source of the Cyclospora outbreak that has now sickened more than 3,000 people across Michigan and Ohio, the first time investigators have pointed to a specific food category since the outbreak began in late June.
Michigan's Department of Health and Human Services announced on July 13, 2026 that its investigation, which involved more than 1,000 patient interviews conducted by state health workers, has pointed to lettuce as a food that "regularly comes up" in those interviews. The state immediately qualified the finding: no specific type of produce, grower, or supplier has been identified as the source, and other food items cannot be completely ruled out.
