# Lettuce Linked to Major Cyclospora Outbreak Affecting Thousands
Michigan health officials have identified leafy greens, specifically lettuce or other salad vegetables, as a probable source of a cyclospora outbreak that has sickened thousands across the United States. The parasitic infection causes severe gastrointestinal distress, including watery diarrhea, abdominal cramps, nausea, and fatigue that can last weeks without treatment.
Cyclospora cayetanensis, a one-celled parasite, spreads through contaminated food and water. The outbreak represents one of several cyclospora incidents linked to fresh produce in recent years. The parasite survives in soil and water and typically affects produce in warm, humid climates where sanitation standards may be inconsistent.
Health officials stressed that their findings remain preliminary. Investigators have not ruled out other foods as contributing sources. The outbreak's scale suggests widespread contamination at some point in the supply chain, from farm through distribution to retail.
For consumers, the CDC recommends washing all produce thoroughly under running water before eating. Cyclospora infections require antibiotic treatment, typically with trimethoprim-sulfamethoxazole. People experiencing severe diarrhea lasting more than a few days should seek medical care and mention potential food exposure to their doctor.
The outbreak underscores ongoing vulnerabilities in produce safety. Food traceability systems help investigators identify sources quickly, but gaps remain. Consumers in affected regions who consumed salad greens recently and developed gastrointestinal symptoms should contact their healthcare provider and report the illness to local health departments.
Officials urged the public to report illnesses while avoiding panic about fresh vegetables broadly. Most produce carries minimal cyclospora risk when handled and prepared properly. Continuing to eat vegetables remains important for health.
