Federal health agencies in the United States have launched a comprehensive investigation following a rapid spike in Cyclospora infections across multiple states. The Centers for Disease Control and Prevention alongside the Food and Drug Administration are actively tracing the source of the parasitic foodborne illness, which is suspected to be linked to contaminated fresh produce.

Cyclospora cayetanensis is a microscopic parasite that causes cyclosporiasis, an intestinal illness marked by severe watery diarrhea, fatigue, and stomach cramps. Health authorities report that cases have surged significantly over the past month, prompting urgent epidemiological tracking. While no specific food item has been definitively identified, past outbreaks have frequently been traced back to imported fresh herbs, berries, or leafy greens.
