Health officials are investigating a rise in cyclosporiasis cases in Hillsdale and St. Joseph counties amid a statewide outbreak of the foodborne illness.
The Branch-Hillsdale-St. Joseph Community Health Agency announced it is tracking local cases, though officials have not confirmed if they are directly linked to the wider Michigan outbreak.
Local residents who receive a call or message from the agency are urged to return the call to help investigators find the source and reduce community risk.
Cyclosporiasis is an illness caused by a tiny parasite spread through food or water contaminated with feces. Past outbreaks have often been linked to fresh produce like leafy greens, cilantro, basil, green onions, raspberries, and snow peas, especially during summer. The infection does not spread from person to person.
Symptoms usually start two to 14 days after exposure. They include watery diarrhea, stomach cramps, bloating, nausea, appetite loss, and a low-grade fever. While the illness can last from a few days to over a month if left untreated, antibiotics can significantly improve symptoms.
Officials advise residents to see a healthcare provider if they experience symptoms.
To lower risks, people should wash their hands, cooking utensils, and produce thoroughly under running water, or choose to cook their fruits and vegetables when possible.
