TL;DR
Health officials warn consumers to avoid certain fresh produce linked to cyclosporiasis outbreaks in the US. The CDC has identified contaminated foods, but investigations are ongoing. Consumers should be cautious until further notice.
Health authorities in the United States have issued warnings to avoid specific fresh produce items due to their association with cyclosporiasis outbreaks. The CDC has confirmed a link between certain foods and cases across multiple states, emphasizing the importance of consumer caution to prevent illness.
The Centers for Disease Control and Prevention (CDC) confirmed that contaminated lettuce and cilantro are linked to the recent surge in cyclosporiasis cases, which have affected at least 12 states as of late April 2026. The outbreaks have resulted in hundreds of reported illnesses, prompting urgent advisories from health officials.
According to the CDC, the implicated foods were traced back to specific suppliers and distributors, with ongoing investigations aiming to identify the exact contamination sources. The CDC recommends that consumers avoid consuming fresh leafy greens, cilantro, and other raw vegetables from certain suppliers until further notice.
Health officials emphasize that proper washing may not eliminate the parasite Cyclospora, which causes cyclosporiasis, and that avoiding these foods is the most effective prevention measure at this stage. No deaths have been reported, but symptoms such as diarrhea, stomach cramps, and nausea have been common among affected individuals.
Why Avoiding These Foods Is Critical for Public Health
This development underscores the ongoing risk of foodborne parasitic outbreaks in the US, highlighting the importance of consumer vigilance and food safety measures. Avoiding contaminated produce can significantly reduce the risk of infection, especially during active outbreaks. The situation also raises concerns about supply chain safety and the need for stricter controls to prevent future incidents. For vulnerable populations, including immunocompromised individuals, avoiding these foods is particularly crucial to prevent severe illness.

Recent Cyclosporiasis Outbreaks and Food Safety Measures
Cyclosporiasis, caused by the Cyclospora parasite, has seen increasing outbreaks in the US over the past decade, often linked to imported produce. The current outbreak, which began in late April 2026, marks one of the largest this year, with health officials tracing cases to specific fresh produce items, notably lettuce and cilantro.
Previous outbreaks in 2024 and 2025 also involved similar produce, prompting calls for improved food safety protocols. The CDC has been working with state and federal agencies to trace contaminated batches and identify the source farms and suppliers involved.
While the exact contamination sources are still under investigation, preliminary findings suggest contamination may have occurred during growing, harvesting, or processing stages. Consumers are advised to heed official warnings and stay updated as investigations progress.
“Consumers should avoid consuming fresh leafy greens and cilantro from specific suppliers until further notice to reduce risk of infection.”

Unresolved Questions About the Contamination Sources
It is not yet clear how the Cyclospora parasite contaminated the affected produce, nor whether the contamination is isolated to specific farms or widespread across multiple suppliers. Investigations are ongoing, and authorities have not yet identified the exact points of contamination within the supply chain.
Additionally, it remains uncertain whether other produce items are at risk, or if imported versus domestic sources are involved. Consumers are advised to stay informed as new details emerge.
