Cyclospora parasite spurs testing options and food‑safety advice in the United States

Cyclospora cayetanensis is a microscopic parasite that can cause cyclosporiasis, an intestinal illness marked by watery diarrhea, stomach cramps, fatigue, fever and other symptoms. Infection occurs when contaminated food or water—often fresh produce such as fruits, vegetables, salads or herbs—is ingested. Recent U.S. outbreaks have been linked to such items, with a few cases reported in Vermont.

Testing for Cyclospora is now offered through a dedicated Cyclospora Infection Test and broader GI Microbiome Profiles from Any Lab Test Now®, helping clinicians confirm the parasite’s presence. The CDC emphasizes that routine stool tests may not include Cyclospora unless specifically requested.

Health officials recommend standard food‑safety practices to reduce risk: wash produce thoroughly, practice hand hygiene, keep raw meats separate from ready‑to‑eat foods, cook foods fully, refrigerate perishables promptly, and stay alert to food recalls.
