A major Cyclospora outbreak has sickened over 1,500 people in Michigan alone, with cases reported in at least 30 states — making it one of the largest in years. The foodborne parasite, linked to contaminated fresh produce, causes weeks of watery diarrhea but is treatable with antibiotics. Experts say there's no need to panic — just wash your produce carefully and practice basic hygiene.
A fast-growing Cyclospora outbreak has put the U.S. on alert, with over 1,500 cases confirmed in Michigan alone and investigations underway in at least 30 states. The microscopic parasite — spread through feces-contaminated irrigation water on fresh produce — causes watery diarrhea, cramps, nausea, and fatigue that can last weeks. No deaths have been reported, and the illness is treatable with the antibiotic trimethoprim-sulfamethoxazole. Health officials have not yet identified the outbreak's source, which experts say may involve multiple contamination points.
Despite the scale of the outbreak, experts urge calm. "We don't need to panic," said Dr. Erika Noel of the University of Hawaii. The health benefits of eating fruits and vegetables still outweigh the risks — but smart food handling matters now more than ever.

Why it matters: This is one of the largest Cyclospora outbreaks in U.S. history, and the source remains unknown — a challenge that could take months to resolve. With summer produce season in full swing, practical food safety steps are the best defense available right now.
