Orlando Daytona Beach Melbourne, FL, July 24, 2026 —
The Centers for Disease Control and Prevention (CDC) has announced that four additional U.S. states have been affected by a growing cyclosporiasis outbreak. The outbreak has been definitively linked to iceberg lettuce imported from central Mexico.
This brings the total number of affected states to an unspecified number beyond the initial group. The CDC has not yet released the names of the four newly identified states, nor has it provided an updated total count of illnesses, hospitalizations, or any potential fatalities associated with the outbreak.
Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. Symptoms typically appear about a week after ingesting the parasite and can include:
- Frequent, sometimes sudden, watery diarrhea
- Loss of appetite
- Weight loss
- Stomach cramps or pain
- Bloating
- Increased gas
- Nausea
- Fatigue
- Loss of energy
- Vomiting (less common)
- Fever (less common)
The CDC continues to investigate the outbreak and is working with relevant health and food safety agencies to determine the source of the contamination and to prevent further illnesses. Consumers are advised to follow guidance from public health officials regarding food safety.
The specific timeline of the outbreak, including when the affected lettuce was distributed and consumed, has not been fully detailed by the CDC. Information regarding any specific retailers or distributors involved in selling the contaminated iceberg lettuce has also not been provided.
Further updates are expected as the investigation progresses.
