The Centers for Disease Control and Prevention (CDC) has confirmed at least 843 cases of cyclosporiasis across more than half of U.S. states since May 1. Cyclosporiasis is an intestinal infection caused by the Cyclospora parasite, which can be contracted through contaminated food or water. The CDC has noted an increase in cases over the past two weeks compared to the same period in 2025, with over 1,500 additional cases under investigation for confirmation as domestically acquired. Symptoms of the infection usually manifest as watery diarrhea within a week of exposure, prompting the CDC to recommend preventive measures for home cooks to reduce the risk of contamination.
Why It Matters
The rise in cyclosporiasis cases highlights ongoing public health concerns regarding food safety in the United States. The CDC emphasizes that the best prevention method is to avoid food or water that may be contaminated with feces. With the current outbreak, it is crucial for consumers to adopt safe food handling practices, especially when preparing fresh produce. Historical data indicates that outbreaks of cyclosporiasis often correlate with contaminated fruits and vegetables, underscoring the need for vigilance in food preparation and hygiene.
