Cyclospora is a microscopic parasite that causes the intestinal illness, cyclospriasis. There are certain produce items that have been historically linked to cyclospora outbreaks including fresh herbs like parsley, cilantro and basil, bagged lettuce and leafy greens, snow peas, scallions and some fruits such as berries, mangos, and prepared fruit salads or fruit trays.

What is Cyclospora?
Know the Symptoms
Symptoms can appear up to two weeks after exposure and may last for several weeks if untreated. Common symptoms include:
- Watery diarrhea
- Frequent or urgent bowel movements
- Stomach cramps or bloating
- Loss of appetite
- Nausea
- Fatigue
- Weight loss
Protect Yourself
Reduce the risk by:
- Rinsing produce well under running water before eating, cutting, or cooking (no need to use soap, detergents, or any "produce cleaner").
- Choosing whole produce instead of pre-cut or bagged options
- Cook fruits, vegetables and herbs when practical, especially for people with weekend immune systems.
- Keep ready-to-eat foods separate from raw produce during preparation.
- Wash hands and use clean cutting boards, utensils, and surfaces to prevent cross-contamination whenever possible.
When to Contact a Healthcare Provider
- Seek medical care if you are experiencing any of the symptoms mentioned before.
- Mention Cyclospora specifically since a standard stool testing may not include this parasite unless a provider orders the appropriate test.
- A healthcare professional can decide whether further testing or prescription medication is appropriate.
