Michigan health officials have released specific, produce-by-produce washing and handling instructions for consumers as the state's Cyclospora outbreak surpassed 1,562 confirmed cases as of July 10, 2026 — the largest outbreak of the parasitic illness in Michigan's history, and the source of which remains unidentified.
The Michigan Department of Health and Human Services released its detailed prevention guidance on July 4 and July 6, 2026, issuing instructions that go further than general "wash your produce" advice — spelling out, vegetable by vegetable, exactly what consumers should buy, how to prepare it, and when cooking is the safest choice.
