Indianapolis, IN, July 29, 2026 —

A significant outbreak of cyclosporiasis has affected an estimated 1 in 1,000 individuals in Michigan over the last three months, state health officials reported. The outbreak is reportedly linked to contaminated shredded iceberg lettuce supplied by Taylor Farms.

As of recent reports, the number of cases in Michigan has surpassed 10,000, making it the largest cyclosporiasis outbreak on record in the United States. The illness has also been detected in at least eight other states, including neighboring Indiana and Ohio, indicating a wider-reaching contamination issue.

Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. Symptoms typically include watery diarrhea, loss of appetite, weight loss, cramping, bloating, and fatigue. Nausea, vomiting, and fever can also occur. Without treatment, symptoms can last for weeks or even months.

Public health agencies are investigating the source of the contamination. While Taylor Farms has been identified as the supplier of the implicated shredded iceberg lettuce, the exact point at which the lettuce became contaminated is still under investigation. Officials have not yet released details regarding specific recall actions or containment measures beyond identifying the product and supplier.

The scale of this outbreak has raised concerns among health officials regarding food safety protocols and supply chain oversight. The investigation is ongoing, with authorities working to determine the full extent of the outbreak and prevent further illnesses. Information regarding specific public health advisories or consumer guidance related to the product is expected as the investigation progresses.
