Wayne County health officials are currently tracking 27 potential cases of cyclosporiasis as part of a broader intestinal illness outbreak affecting more than 300 people across Michigan. The outbreak, caused by the parasite Cyclospora cayetanensis, is currently under investigation by the Wayne County Public Health department in coordination with the Michigan Department of Health and Human Services and the Michigan Department of Agriculture and Rural Development.
What is Cyclosporiasis and How Does it Spread?
Cyclosporiasis is an intestinal infection triggered by the Cyclospora cayetanensis parasite. According to state health officials, the illness is primarily transmitted through the ingestion of food or water contaminated with the parasite. It is not typically spread from person to person.
In the United States, outbreaks have most often been linked to contaminated fresh produce.
Symptoms can take one to two weeks to appear after exposure.
Recognizing the Symptoms of Infection
The clinical presentation of cyclosporiasis involves significant gastrointestinal distress. According to health authorities, symptoms typically manifest about one week after exposure, though they can appear anywhere from two to 14 days later.
- Watery diarrhea
- Loss of appetite
- Abdominal cramps
- Nausea and fatigue
- Low-grade fever
Without treatment, the illness can last several days to more than a month, and symptoms may return even after temporary improvement.
How Can You Protect Yourself?
While the investigation into the source of the current Michigan outbreak remains ongoing, officials emphasize standard food safety protocols to minimize risk. Most infections can be treated with prescription antibiotics.

Pro Tips for Food Safety:
- Wash thoroughly: Rinse fresh fruits and vegetables under running water.
- Scrub firm items: Scrub firm produce with a clean produce brush.
- Handle carefully: Remove damaged portions of fruits and vegetables.
- Temperature control: Refrigerate cut produce promptly.
- Hygiene: Wash hands before preparing or eating food.
Future Trends in Foodborne Illness Tracking
State health officials said part of the recent increase in reported cases may be due to greater awareness of the outbreak.
