Cyclosporiasis infections in the United States have reached higher-than-expected levels this year, according to data from the Centers for Disease Control and Prevention (CDC). This intestinal illness is caused by the microscopic parasite Cyclospora cayetanensis and is typically transmitted through the consumption of food or water contaminated with feces. While not usually life-threatening, the infection causes prolonged, watery, and often explosive diarrhea that can last for weeks if left untreated.
Understanding the Cyclosporiasis Outbreak
While the summer months historically see a rise in cases, public health officials are monitoring an elevated number of infections this season. The illness can persist for several weeks or even months if the patient does not receive appropriate antibiotic treatment.
Common Sources of Contamination
In the United States, outbreaks of cyclosporiasis are frequently linked to the consumption of imported or domestic fresh produce.
According to the U.S.
- Fresh cilantro
- Basil
- Raspberries
- Snow peas
- Mesclun lettuce
- Pre-packaged salad mixes
The FDA’s Coordinated Outbreak Response and Evaluation (CORE) Network actively investigates these clusters to identify specific contaminated supply chains. By tracing the distribution of produce like cucumbers, white onions, and cilantro, agencies aim to pinpoint the source of contamination and remove affected items from the marketplace.
Prevention and Safety Guidelines
The most effective way to reduce the risk of infection is to cook produce thoroughly, which kills the parasite.
