Cyclosporiasis Outbreak: How to Protect Yourself From Tainted Produce
A cyclosporiasis outbreak has sickened roughly 6,700 people since May. Experts urge skipping raw lettuce and cooking other greens.
A parasitic illness called cyclosporiasis has infected approximately 6,700 Americans since May, raising urgent concerns about fresh produce safety heading into the summer and fall eating seasons. The outbreak, which causes prolonged diarrhea and other gastrointestinal symptoms, has prompted health advisories urging consumers to rethink how they handle and prepare leafy vegetables.
Among the most direct pieces of guidance circulating: skip the lettuce entirely for now, at least in its raw form. Because cyclospora is a microscopic parasite that clings to fresh produce and is not reliably removed by a simple rinse, raw leafy greens carry an elevated risk during an active outbreak. Washing does reduce surface contamination, but health experts caution it is not a foolproof safeguard against the parasite.

For other greens — spinach, kale, Swiss chard and similar vegetables — cooking offers a reliable kill step that raw preparation simply cannot match. Heat destroys cyclospora, meaning sautéed, steamed or otherwise cooked greens present a dramatically lower risk than their salad-bowl counterparts. Consumers who want the nutritional benefits of greens without elevated exposure risk are advised to pivot toward cooked preparations until the outbreak is contained.
Cyclosporiasis is caused by ingesting food or water contaminated with Cyclospora cayetanensis. Symptoms typically emerge about a week after exposure and can persist for weeks without antibiotic treatment, making early medical attention important for anyone experiencing sudden, watery diarrhea. The outbreak's scale — nearly 6,700 cases since May — underscores how quickly a produce-linked pathogen can move through a food supply chain that spans multiple states and distribution networks.
Public health officials continue to investigate the specific produce items driving transmission, and consumers should monitor updates from the CDC and local health departments for the latest guidance. Continue reading at MarketWatch.com
