Health officials in the United States are continuing to investigate a large Cyclospora outbreak that has affected multiple states, with thousands of confirmed illnesses reported this year.
The outbreak is caused by Cyclospora cayetanensis, a microscopic parasite that spreads through contaminated food or water. Public health agencies are working to determine the exact source while urging consumers to practice safe food handling.
What Is Cyclospora?
Cyclospora is a parasite that infects the intestines and causes cyclosporiasis, a foodborne illness that primarily affects the digestive system.
People typically become infected after consuming fresh produce or water contaminated with the parasite. Unlike many bacteria, Cyclospora cannot be spread directly from one person to another because it must first mature in the environment.
Common Symptoms
Symptoms usually begin about one week after exposure and may include:
- Watery diarrhea
- Frequent bowel movements
- Stomach cramps
- Nausea and vomiting
- Fatigue
- Loss of appetite
- Weight loss
- Low-grade fever
Without treatment, symptoms can last for several weeks or even recur after improving.
Foods Under Investigation
Investigators are examining several fresh produce items that have been associated with Cyclospora outbreaks, including:
- Iceberg lettuce
- Cilantro
- Parsley
- Leafy greens
Officials say the investigation is ongoing, and not every product in these categories is considered unsafe. Some recalls have been issued during the investigation, while the source of many cases remains under review.
How to Reduce Your Risk
Health experts recommend:
- Wash fruits and vegetables thoroughly before eating.
- Refrigerate fresh produce properly.
- Avoid consuming recalled products if announced by health authorities.
- Cook vegetables when possible, as heat can destroy the parasite.
- Wash hands before preparing or eating food.
Investigation Continues
The CDC and FDA continue to work with state health departments to identify the source of the outbreak and prevent additional illnesses. Officials encourage anyone experiencing persistent diarrhea or severe dehydration to seek medical care promptly.
