The Michigan cyclosporiasis outbreak has grown to 10,773 confirmed and probable cases after state health officials reported 387 new infections on Friday. The latest update comes as the multistate outbreak continues to spread across the United States, with federal investigators tracing many cases to contaminated iceberg lettuce.
The Michigan Department of Health reported that the outbreak has now resulted in 193 hospitalizations. Officials have not reported any deaths linked to the illness.
Michigan Cyclosporiasis Outbreak: What Is Cyclosporiasis?
Cyclosporiasis is an intestinal illness caused by the Cyclospora parasite.
The infection usually causes diarrhea, nausea, stomach cramps, fatigue, bloating, and loss of appetite. Symptoms can last for days or even weeks if patients do not receive treatment.
Health experts recommend seeking medical care if symptoms persist.
Michigan Cyclosporiasis Outbreak Linked to Iceberg Lettuce
The U.S. Food and Drug Administration (FDA) has linked the outbreak to iceberg lettuce supplied by privately owned Taylor Farms operations in central Mexico.
Investigators believe the lettuce is responsible for many infections. However, they continue searching for additional sources because the outbreak now affects nine states.
Consumers have also reduced lettuce purchases because of food safety concerns and uncertainty over affected products.
CDC Monitors the Michigan Cyclosporiasis Outbreak
The Centers for Disease Control and Prevention (CDC) reported 6,707 laboratory-confirmed cases of cyclosporiasis since May 1.
Officials are also reviewing more than 11,500 suspected cases that still require confirmation or further investigation.
The CDC noted that its national figures include only confirmed infections. State reports may contain both confirmed and probable cases, which explains why state totals can appear higher.
Michigan Cyclosporiasis Outbreak Sends More Patients to Hospital
Healthcare analytics company Truveta reported that cyclosporiasis diagnoses this July were more than 11 times higher than the average recorded during the past eight years.
The company also found that:
- More than 20% of patients visited an emergency department within two weeks of diagnosis.
- Nearly one in eight patients required hospitalization.
The findings highlight the growing impact of the outbreak on healthcare systems.
Experts Raise Concerns About Outbreak Response
Former CDC officials and food safety experts say recent staffing cuts across federal health agencies have complicated the government’s response to foodborne disease outbreaks.
They warn that reduced resources may slow investigations and delay efforts to identify contaminated food products.
