Investigators linked certain bagged lettuce products to the parasite, prompting recalls by producers including Taylor Farms and some restaurant suppliers. The FDA later acknowledged a lab test produced a false positive and apologized, though recalls remain active while inquiries continue.
Cyclospora is a microscopic parasite spread most often through contaminated produce. Illness can include severe, prolonged diarrhoea, nausea and fatigue, and symptoms may last for days or recur over weeks.
