Monroe County reports eight cyclosporiasis cases amid regional outbreak; Health officials reiterate safety guidance

BLOOMINGTON The Monroe County Health Department (MCHD) continues to actively monitor local and regional cyclosporiasis activity as part of an ongoing multistate outbreak that began earlier this summer.

According to data from the Indiana Department of Health (IDOH), eight cases of cyclosporiasis have been reported in Monroe County since May 1, 2026.

Despite recent news of fatalities reported in a neighboring state, local health officials emphasize that Monroe County’s risk level and public guidance remain unchanged.

What Is Cyclosporiasis?

Cyclosporiasis is an intestinal illness caused by a microscopic parasite. It is most commonly spread through the consumption of contaminated fresh produce, particularly leafy greens, herbs, and berries.

Symptoms typically appear about one week after exposure—though the onset range can span from 2 to 14 days—and may include:

  • Watery, sometimes explosive diarrhea
  • Loss of appetite, stomach cramping, or bloating
  • Nausea or vomiting
  • Fatigue and, less commonly, a low-grade fever

While symptoms can persist from a few days to several weeks, most healthy individuals recover on their own. Effective antibiotic treatments are available when medical intervention is needed.

Recent Regional Updates & Local Risk

Public health officials in Michigan recently confirmed two deaths linked to their state’s outbreak. Both individuals had significant underlying health conditions that may have been complicated by the parasitic infection and subsequent dehydration.

MCHD noted that deaths from cyclosporiasis are uncommon and that the vast majority of infected individuals recover without serious complications. The tragic events in Michigan do not signal a heightened risk level for Monroe County residents, but they do serve as a critical reminder that severe outcomes can occur—particularly for vulnerable populations.

Recommended Precautions for Residents

MCHD urges community members to remain vigilant, place extra emphasis on food safety, and seek medical care promptly if symptoms are severe or prolonged.

Health officials recommend the following measures:

  • Opt for Whole Produce: Choose whole produce over pre-cut or bagged items whenever possible. For example, purchase whole heads of lettuce instead of pre-washed, bagged salad mixes.
  • Wash Produce Thoroughly: Remove and discard the outer two to three layers of leafy greens, then thoroughly rinse the remaining leaves under running water.
  • Cook When Practical: Thoroughly cooking leafy greens reliably kills the parasite.
  • Practice Good Hygiene: Maintain careful handwashing habits to prevent spreading the illness to others within your household.
  • Monitor for Symptoms: Contact a healthcare provider if you experience persistent diarrhea—especially if you show signs of dehydration (such as dizziness, dark urine, or reduced urination)—or if you are pregnant, elderly, immunocompromised, or caring for a young child.

Proper diagnosis of cyclosporiasis requires a stool sample test ordered by a healthcare provider.

MCHD will continue to track local data and coordinate with both the IDOH and the U.S. Centers for Disease Control and Prevention (CDC). Health officials will issue further public updates should local guidance or risk levels change.
