Health authorities in the United States have officially expanded the scope of an ongoing investigation into a Cyclospora outbreak. The parasitic illness, which typically causes symptoms such as watery diarrhea, cramping, and fatigue, has now been linked to iceberg lettuce in three states beyond those previously identified.

Cyclospora cayetanensis is a microscopic parasite that infects the small intestine, usually transmitted through the consumption of contaminated food or water. While the investigation is ongoing, officials are focusing on iceberg lettuce as the primary vehicle for the current cluster of infections. The Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) are working to trace the supply chain to determine exactly where the contamination occurred.

At this stage, the specific states involved in the expansion have not been fully detailed in public reports, but the confirmation marks a significant development in the effort to contain the spread. Consumers are generally advised to follow standard food safety protocols, such as washing produce thoroughly, though officials note that this may not always eliminate the risk of Cyclospora contamination. The investigation remains active as health departments continue to monitor for new cases and analyze data from affected individuals to pinpoint the specific source of the contaminated lettuce.
