A parasitic intestinal illness has swept through Michigan at a pace state health officials say is nearly 20 times higher than anything the state has seen before. As of 9:30 a.m. on July 8, 2026, the Michigan Department of Health and Human Services (MDHHS) confirmed 992 cases of cyclosporiasis since June 22 — up from just 700 cases reported two days earlier. At least 36 people have been hospitalized.
No specific food, grower, or supplier has yet been identified as the source. The outbreak is centered in southeast Michigan but has now spread to neighboring states, triggering investigations across at least 28 other states, including Ohio, New York, and Illinois.
