Background on Cyclospora and Recent Outbreak Trends
Cyclospora cayetanensis is a parasitic organism that causes cyclosporiasis, leading to gastrointestinal illness. Outbreaks linked to contaminated produce, especially berries and leafy greens, have been reported periodically in the U.S. over the past decade. The current surge appears to be one of the largest in recent years, with health officials noting increased cases since early this month. Similar outbreaks in previous years have been traced to imported produce, emphasizing the importance of food safety controls in the supply chain.
“We are actively investigating the sources of this outbreak, focusing on contaminated produce and water supplies. Consumers should remain vigilant and follow safety guidelines.”
— Dr. Jane Smith, CDC Epidemiologist
