Colorado health officials are urging residents to remain vigilant after a growing number of cyclosporiasis cases were reported across the state. The illness, caused by the microscopic parasite Cyclospora cayetanensis, is commonly linked to contaminated fresh produce and can spread through food or water that has been exposed to the parasite. Investigators are working to determine whether the recent illnesses share a common source.
People infected with Cyclospora often develop symptoms several days to two weeks after consuming contaminated food or water. The most common sign is prolonged watery diarrhea, though many patients also experience stomach cramps, nausea, fatigue, loss of appetite, bloating, and weight loss. Without treatment, symptoms can last for weeks or even return after initially improving.
Investigation Continues as Source Remains Unknown :
Public health officials are interviewing patients and reviewing recent food purchases and dining histories to identify any common links. At this stage, no single restaurant, grocery store, or food product has been confirmed as the source of the outbreak. Additional testing and trace-back investigations are underway to determine where the contamination may have occurred.
Cyclosporiasis outbreaks are often associated with fresh fruits and vegetables that are eaten raw, including leafy greens, herbs, berries, and imported produce. Because the parasite requires time in the environment before becoming infectious, it is not typically spread directly from one person to another.
How to Protect Yourself :
Health experts recommend washing fresh fruits and vegetables thoroughly before eating or preparing them, although rinsing alone may not remove all traces of the parasite. Practicing good hand hygiene, using safe drinking water, and following food safety guidelines can help reduce the risk of illness.
Anyone experiencing persistent diarrhea lasting more than a few days, especially after eating fresh produce or traveling, should contact a healthcare provider. Cyclosporiasis is treatable with prescription antibiotics, and early diagnosis can help shorten the duration of illness and prevent complications.
What Residents Should Watch For :
Officials continue to monitor the situation and encourage anyone diagnosed with cyclosporiasis to cooperate with public health investigators. Information collected from patients plays a critical role in identifying potential sources and preventing additional infections.
While the investigation remains active, residents are encouraged to stay informed through updates from state and local health agencies. Public health experts emphasize that awareness, proper food handling, and prompt medical attention are the best tools for limiting the spread of this seasonal foodborne illness while investigators work to identify its source.
