Health officials have confirmed an outbreak of cyclosporiasis affecting multiple states in the United States, linked to contaminated fresh produce. You can read more about the Outbreak Of Cyclosporiasis for detailed information. The Centers for Disease Control and Prevention (CDC) announced the outbreak on March 15, 2024, emphasizing the importance of public awareness and ongoing investigation.
The CDC reported that over 100 cases have been confirmed across at least five states, including Ohio, Indiana, and Illinois. The illnesses are associated with the consumption of raw vegetables and fruits, particularly salad mixes and berries, which testing has linked to the parasite Cyclospora cayetanensis. Laboratory analysis of samples from affected food sources and patients’ stool specimens has confirmed the presence of Cyclospora.

Why This Outbreak Matters for Public Health
This outbreak highlights the ongoing risk of foodborne parasitic infections from contaminated produce, especially in the context of globalized food supply chains. Cyclosporiasis can cause severe gastrointestinal illness, particularly in vulnerable populations such as the immunocompromised, and can lead to prolonged symptoms if not properly treated. The incident underscores the importance of food safety measures, proper hygiene practices, and rapid response to emerging outbreaks to prevent widespread illness.

Recent Trends and Past Cyclosporiasis Outbreaks
Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, which is transmitted through ingestion of contaminated food or water. The U.S. has experienced multiple outbreaks over the past decade, often linked to imported produce such as berries, lettuce, and cilantro. The CDC has issued previous warnings during peak seasons, usually in the spring and summer, when produce contamination risks increase.
The current outbreak follows similar patterns, with initial reports emerging from Ohio and Indiana in early March. The CDC and FDA have previously identified contaminated imported produce as a common source, emphasizing the need for stricter import controls and better farm hygiene practices.
“We are actively investigating the source of this outbreak and are working with partners across the supply chain to identify contaminated products and prevent further cases.”
— Dr. Anne Miller, CDC Epidemiologist
