Health officials are tracking a significant rise in cyclosporiasis cases across the United States. As of mid-June 2026, the Centers for Disease Control and Prevention confirmed 145 domestically acquired cases of this foodborne illness in 17 states.
The FDA has launched an investigation into possible contaminated food sources. No specific product has been identified yet, but the pattern points to fresh produce consumed in the US.
People affected report being stuck dealing with severe symptoms for days. The outbreak has led to 20 hospitalizations, though no deaths have been reported.
What Is Cyclosporiasis?
Cyclosporiasis is an intestinal infection caused by the microscopic parasite Cyclospora cayetanensis. The parasite spreads through food or water contaminated with feces. It does not spread directly from person to person.
Outbreaks often occur in spring and summer months and have previously been linked to items such as raspberries, basil, cilantro, and leafy greens.

Symptoms of Cyclosporiasis
Infected individuals typically experience watery diarrhea that can be frequent and explosive. Other common symptoms include:
- Loss of appetite and significant weight loss
- Stomach cramps, bloating, and increased gas
- Nausea, vomiting, and fatigue
- Headache, body aches, and low-grade fever
Symptoms usually appear about one week after exposure and can last for weeks or longer without proper treatment. Many people feel extremely weak and dehydrated due to prolonged diarrhea.
Current Status of the Investigation
CDC data shows cases reported in 17 states among people who ate food inside the United States and had no recent international travel.

Local, state, and federal agencies including the FDA are actively investigating multiple clusters. Traceback efforts continue to identify the exact source of contamination.
New York has reported the highest number of cases, followed by states such as Illinois and Texas. Officials continue to monitor the situation closely.
How to Protect Yourself from Cyclosporiasis
While the investigation is ongoing, public health experts recommend these practical steps:
- Wash all fresh fruits and vegetables thoroughly under running water before eating
- Peel produce when possible
- Cook vegetables and fruits when feasible, as heat can help reduce risk
- Avoid raw produce from sources with known outbreak links during high-risk periods
- Practice good hand hygiene, especially after using the bathroom and before handling food
Rinsing alone may not fully remove the parasite, so extra caution with raw items is advised.
What to Do If You Have Symptoms
If you experience prolonged watery diarrhea or other symptoms consistent with cyclosporiasis, contact your healthcare provider promptly. Early diagnosis and treatment with antibiotics can shorten the illness and prevent complications.
Stay updated through official sources such as the CDC and FDA for the latest guidance on this outbreak.
