Dozens hospitalized with cyclosporiasis as cases of gastrointestinal illness spike in 32 states
The CDC said 843 cases have been confirmed and more than 1,500 others are still under investigation as the outbreak spreads.
- The Centers for Disease Control and Prevention reported Friday that cyclosporiasis has spread to 32 states, with 86 people hospitalized and an NBC News tally showing 2,912 cases reported or confirmed nationwide.
- Cyclosporiasis is a foodborne illness caused by a microscopic parasite called Cyclospora, often linked to contaminated fresh produce, with symptoms appearing between two and 14 days after exposure.
- Michigan reported 1,562 cases as of Friday; Dr. Natasha Bagdasarian, chief medical executive of Michigan, described the rapid rise as "highly unusual" compared to the state's typical 40 to 50 annual cases.
- With no product recalls issued, health officials have not identified the contaminated food source; the Food and Drug Administration said Friday it was "actively engaged" with state partners investigating.
- Experts advise thoroughly washing and scrubbing produce to reduce parasite growth, especially during the May-to-August peak season; the CDC made state reporting optional in 2025, complicating accurate outbreak counts.
