The U.S. Centers for Disease Control and Prevention (CDC), Food and Drug Administration (FDA), and state health officials are investigating a multistate Cyclospora outbreak, including a five-state cluster linked to iceberg lettuce. Taylor Farms also recalled iceberg lettuce sourced from central Mexico on July 17.
Since May 1, 2026, the CDC has reported 4,173 lab-confirmed cases and is reviewing more than 7,400 additional suspected cases, many from Michigan and Ohio. Because many people recover without testing, officials believe the actual number may be higher.
Michigan has reported more than 7,000 total cases, including probable cases still under review. As of July 23, the state reported 7,664 cases and 160 hospitalizations. Lettuce or other salad greens may be a source, though no specific grower or supplier has been confirmed.
What You Should Do
If you have symptoms of cyclosporiasis, especially watery diarrhea, contact your healthcare provider and stay hydrated. Other common symptoms include fatigue and loss of appetite, and they may begin about a week after infection.
The CDC advises consumers not to eat recalled lettuce, to throw it away or return it, and to wash any surfaces or items it may have touched. If you're dining out and can't confirm the source of iceberg lettuce, avoid ordering it.
If you become ill, health officials may ask about foods you ate in the two weeks before symptoms began. With cases expected to rise through August, staying current on recalls and outbreak updates is an important way to protect your household.
