More than 60 North Carolina cases tied to parasite behind 'explosive diarrhea'

July 3, 2026 - 19:16

Health officials in North Carolina are reporting a significant uptick in infections caused by Cyclospora, a single-celled parasite that triggers severe gastrointestinal distress. More than 60 cases have now been confirmed across the state, with symptoms often described as violent and sudden. The parasite is notorious for causing "explosive diarrhea," along with cramping, nausea, and prolonged fatigue.

The outbreak has prompted state health authorities to issue warnings about the source of the contamination. Cyclospora is typically spread through contaminated food or water, often linked to fresh produce imported from tropical regions. Common culprits include berries, herbs, and salad greens. Unlike many foodborne illnesses, this parasite requires a specific lab test to diagnose, meaning many cases may go unreported.

Officials are urging anyone experiencing watery diarrhea that lasts more than a few days, especially if accompanied by loss of appetite or weight loss, to seek medical attention. Treatment usually involves a course of antibiotics. The state is currently working with local health departments to trace the origin of the contaminated food, though no single source has been identified yet. Residents are advised to wash all produce thoroughly and be cautious with raw fruits and vegetables.
