TL;DR
Health authorities are investigating an outbreak of cyclosporiasis, a parasitic illness. Confirmed symptoms include diarrhea, stomach cramps, and nausea. The situation is ongoing, and public health officials advise caution with certain foods.
Health officials are investigating a recent outbreak of cyclosporiasis, a parasitic intestinal illness, which has resulted in multiple reported cases across several states. This outbreak highlights ongoing food safety concerns and the need for public awareness about symptoms and prevention. The Centers for Disease Control and Prevention (CDC) confirmed that affected individuals are experiencing common symptoms such as diarrhea, stomach cramps, nausea, and fatigue. This development matters because it highlights ongoing food safety concerns and the need for public awareness about symptoms and prevention.
The CDC reported that over 100 cases of cyclosporiasis have been identified in the past month, with cases concentrated mainly in the Midwest and Northeast regions. Laboratory tests confirmed the presence of Cyclospora cayetanensis, a microscopic parasite that causes the illness. For more details, see the recent investigation into cases of intestinal illness in Lucas and Monroe counties. Health authorities have linked several cases to contaminated fresh produce, particularly imported berries and lettuce, though investigations are still ongoing to identify specific sources.
Symptoms typically develop between 2 to 14 days after ingestion of contaminated food or water. If you experience persistent symptoms, it’s important to seek medical care and stay informed about ongoing outbreaks like the West Virginia Cyclosporiasis Outbreak. The most common symptoms include profuse diarrhea, stomach cramps, bloating, nausea, and fatigue. In some cases, symptoms can persist for weeks if untreated, and the illness can cause dehydration and weight loss, especially in vulnerable populations.
Officials emphasize that cyclosporiasis is not transmitted from person to person but through ingestion of contaminated food or water. Treatment generally involves antibiotics such as trimethoprim-sulfamethoxazole, and affected individuals are advised to stay hydrated and seek medical care if symptoms worsen.
Implications for Food Safety and Public Health
This outbreak underscores the importance of food safety measures, especially for imported produce. It also highlights the need for consumers to be aware of symptoms and seek prompt medical attention. Public health agencies are working to trace the source of contamination to prevent further cases, and the incident raises ongoing concerns about the safety of fresh produce imports.

Recent Cyclosporiasis Cases and Food Safety Measures
Cyclosporiasis, caused by the parasite Cyclospora cayetanensis, has been a recurring concern in the U.S., often linked to imported fresh produce. The CDC has previously issued warnings during similar outbreaks, typically associated with berries or leafy greens. The current investigation follows a pattern of outbreaks linked to produce imported from regions with less stringent food safety regulations. Historically, outbreaks tend to peak during warmer months when fresh produce consumption increases.
Authorities have increased testing and inspection of imported produce, and consumers are advised to wash fruits and vegetables thoroughly. The CDC continues to monitor the situation, with investigations ongoing to identify specific contaminated sources and prevent future cases.
“We are actively investigating this outbreak and urge consumers to practice good hygiene and proper food handling to reduce risk.”
— Dr. Anne Schuchat, CDC Senior Advisor

It is transmitted through ingestion of contaminated food or water containing the Cyclospora parasite. It is not spread from person to person.
Can cyclosporiasis be treated?
Yes. It is typically treated with antibiotics such as trimethoprim-sulfamethoxazole. Hydration and medical supervision are recommended.
What foods are most likely to carry Cyclospora?
Contaminated produce such as berries, lettuce, and other leafy greens are most commonly associated with outbreaks.
Is there a risk of severe illness?
While most healthy individuals recover fully, vulnerable populations such as the elderly or immunocompromised may experience more severe symptoms or complications.
