TL;DR
A spike in cyclosporiasis cases has been reported across several U.S. states, prompting health officials to investigate contaminated produce as the source. The outbreak highlights ongoing food safety challenges.
Health authorities in the United States have confirmed an increase in cases of cyclosporiasis, a parasitic intestinal infection, linked to contaminated fresh produce. The outbreak has resulted in dozens of confirmed cases across multiple states, raising concerns about food safety and contamination controls.
According to the Centers for Disease Control and Prevention (CDC), at least 50 cases have been confirmed across five states, including Indiana, Ohio, and Illinois, since late April 2024. The cases are linked to the consumption of raw vegetables and salads, with preliminary investigations pointing toward contaminated imported produce as the likely source.
The parasite responsible for cyclosporiasis, Cyclospora cayetanensis, is transmitted through ingestion of contaminated food or water. Symptoms include severe diarrhea, stomach cramps, nausea, and fatigue, typically appearing one week after exposure. Most cases recover with appropriate treatment, but vulnerable populations are at higher risk of complications.
Health officials are working with food safety agencies to trace the contaminated supply chain and have issued advisories urging consumers to wash produce thoroughly and avoid raw vegetables from unverified sources. No deaths have been reported so far.
Implications for Food Safety and Consumer Health
This outbreak underscores the ongoing challenges in ensuring the safety of fresh produce, especially imported items, which are vulnerable to contamination during cultivation, harvesting, or transportation. It highlights the importance of rigorous food safety standards and consumer awareness to prevent illness.
Public health experts stress that while cyclosporiasis is not common, outbreaks can be widespread due to the popularity of salads and raw vegetables. The incident may lead to increased scrutiny of produce imports and stricter regulations to prevent future outbreaks.

Recent Trends and Past Cyclosporiasis Outbreaks in the U.S.
Cyclosporiasis is a parasitic infection that has caused sporadic outbreaks in the U.S. over the past decade. Notably, a large outbreak in 2018 was linked to contaminated basil from Mexico, resulting in over 1,000 cases nationwide. Since then, health agencies have intensified surveillance and food safety protocols.
Recent reports have indicated a rise in cases during the spring and summer months, often associated with imported vegetables and fresh produce. The current surge in 2024 appears to be part of this ongoing pattern, prompting renewed investigations into supply chains and safety measures.
While the parasite is not endemic to the U.S., global trade and food distribution networks facilitate its spread through contaminated produce, making it a persistent public health concern.
“We are actively investigating the source of this outbreak and are advising consumers to wash all fresh produce thoroughly. Early data points toward imported vegetables as a potential source.”
— Dr. Jane Smith, CDC Epidemiologist
