TL;DR
More than 1,000 cases of cyclosporiasis have been confirmed in the US, primarily linked to contaminated fresh produce. Health authorities are investigating the outbreak, which causes gastrointestinal illness.
Health officials have confirmed more than 1,000 cases of cyclosporiasis across the United States, linked to contaminated produce, making it one of the largest outbreaks of this parasite in recent years. The outbreak has prompted investigations into food sources and raised public health concerns about food safety and gastrointestinal illnesses.
The Centers for Disease Control and Prevention (CDC) announced that over 1,000 cases of cyclosporiasis have been confirmed in multiple states since late April 2024. The majority of cases are associated with the consumption of fresh produce, particularly leafy greens and berries, which are believed to have been contaminated with the Cyclospora cayetanensis parasite.
Health officials have identified several distribution centers and retail outlets linked to the contaminated produce, though a definitive source has not yet been publicly confirmed. No deaths have been reported, but hundreds of patients have experienced prolonged diarrhea, stomach cramps, and other gastrointestinal symptoms.
The CDC and Food and Drug Administration (FDA) are conducting investigations, including testing of food samples and traceback efforts to identify the contamination source. The outbreak is ongoing, and health authorities advise consumers to wash produce thoroughly and stay alert for symptoms.
Public Health Impact of the Cyclosporiasis Outbreak

With over 1,000 confirmed cases, it highlights the need for improved monitoring and regulation of food supply chains. The illness can cause prolonged gastrointestinal symptoms, impacting quality of life and healthcare resources. The outbreak also raises concerns about the effectiveness of current safety measures for produce imported from regions where Cyclospora is endemic.

Background and Previous Cyclosporiasis Outbreaks in the US
Cyclosporiasis is caused by the Cyclospora cayetanensis parasite, which is transmitted through ingestion of contaminated food or water. The parasite is endemic in some regions and has been linked to outbreaks in the US over the past decade, often associated with imported produce. Notable previous outbreaks include the 2018 multistate outbreak linked to basil and other herbs. The current surge in cases is among the largest in recent years, prompting renewed focus on food safety practices.
