Leafy Greens Repeatedly Linked to Foodborne Illness Outbreaks

A recent cyclospora outbreak tied to lettuce is the latest in a long series of foodborne illness events linked to leafy greens. Cyclospora is a microscopic parasite that causes prolonged diarrhea and gastrointestinal distress in infected individuals. Leafy greens are particularly vulnerable to contamination due to their close contact with soil, water, and agricultural environments where pathogens can thrive. Unlike meats, greens are often consumed raw, meaning there is no cooking step to kill harmful organisms before they reach consumers. Experts note that this recurring pattern points to systemic challenges in the safety of leafy green produce supply chains.
