America’s Homegrown-Parasite Problem

A Cyclospora cayetanensis outbreak has sickened over 2,900 people in the U.S., causing cyclosporiasis with severe diarrhea. Michigan reported 1,500 cases during the current outbreak, far exceeding its usual annual total. The FDA established a task force in 2019, but the surge persists, with possible links to domestic produce or contaminated water sources like Lake Erie.
