The nationwide outbreak of cyclosporiasis—a foodborne illness caused by the microscopic parasite Cyclospora cayetanensis—has surpassed historical records. Federal health reports indicate over 18,000 to 20,000 confirmed or suspected cases across more than 30 states, marking the largest outbreak of the parasite in U.S. history.
Florida Case Numbers & Breakdown
Florida has experienced a significant seasonal spike in cyclosporiasis. State health department data reveals 254 cases statewide (248 confirmed and 6 probable).
The highest concentrations in Florida are reported in:
- Miami-Dade County: 40 cases
- Lee County: 23 cases
- Broward County: 22 cases
- Orange County: 21 cases
- Collier County: 6 cases
Outbreak Source & Key Details
- National Deaths: State officials in Michigan announced the first 2 deaths tied to this national outbreak. Both individuals had underlying health conditions that were aggravated by intestinal illness and severe dehydration. Cyclosporiasis is rarely fatal in otherwise healthy individuals.
- Contamination Source: Federal health agencies (CDC and FDA) traced a major branch of the outbreak to contaminated lettuce imported from Mexico. Specific recalls have involved fresh produce suppliers, including select lettuce products from Taylor Farms.
- Symptoms & Treatment: Infection typically causes severe, watery diarrhea, abdominal cramping, nausea, fatigue, and explosive bowel movements. Symptoms can take 2 to 14 days to appear after ingestion. Unlike standard bacterial food poisoning, Cyclospora requires targeted prescription antibiotics (such as Trimethoprim-sulfamethoxazole / Bactrim) to treat effectively.
