The Centers for Disease Control and Prevention (CDC) confirmed that multiple cases of cyclosporiasis have been reported in at least five states, including Indiana and Ohio. The outbreak appears to be associated with fresh produce, with preliminary evidence pointing to contaminated leafy greens and berries. Health officials advise consumers to avoid eating certain raw vegetables and fruits until further notice. For more details, see Cyclosporiasis Symptoms.
According to the CDC, symptoms of cyclosporiasis typically include diarrhea, stomach cramps, and nausea, usually appearing one week after ingestion of contaminated food. The agency is working with food suppliers and local health departments to identify the source of contamination and prevent further cases. No deaths have been reported so far, but dozens of infections have been confirmed.
Why This Outbreak Urges Caution for Consumers
This outbreak underscores the importance of food safety and proper handling of fresh produce. As cyclosporiasis is transmitted through ingestion of contaminated food or water, avoiding specific raw produce can help reduce infection risk. For consumers, awareness of which foods are implicated is crucial for health and safety, especially during outbreaks.
The outbreak also highlights the need for stricter food supply chain controls and improved hygiene practices among growers and vendors. Public health agencies stress that while the contaminated foods are identified as the primary source, ongoing investigations may expand or refine these recommendations.

Background on Cyclosporiasis and Recent Outbreaks
Cyclosporiasis is caused by the protozoan parasite Cyclospora cayetanensis, which is transmitted through ingestion of contaminated produce, often imported from regions with less stringent food safety measures. Outbreaks have occurred periodically in the US, with notable spikes in recent years linked to imported berries and leafy greens.
The current outbreak began surfacing in late April 2026, with health officials noting an unusual increase in cases across multiple states. Past outbreaks have prompted recalls and advisories, but ongoing investigations aim to pinpoint the exact source of contamination this time.
“Consumers should avoid eating raw leafy greens and berries until further notice, as investigations continue into the contaminated sources.”
