Buncombe County -- July 18, 2026: Buncombe County Public Health is encouraging residents to take extra precautions when handling and preparing fresh fruits and vegetables as cases of cyclosporiasis continue to increase across North Carolina during the summer months.
Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora, which is spread by consuming food or water contaminated before it reaches consumers. While the illness is generally not life-threatening, it can become serious enough to require hospitalization, particularly for individuals with weakened immune systems or other underlying health conditions.
Cases Continue to Increase Across North Carolina
Between May 1 and July 14, 2026, North Carolina reported 307 confirmed cases of cyclosporiasis and 13 hospitalizations. The North Carolina Department of Health and Human Services continues to monitor the outbreak through a statewide dashboard that is updated weekly.
Locally, Buncombe County has confirmed four cases, while Henderson County has reported seven confirmed cases. Health officials say investigators have not identified a single food item responsible for the infections in North Carolina, and the state's cases have not been linked to outbreaks occurring in other parts of the country.
Understanding Cyclosporiasis
Cyclospora is a microscopic parasite that can contaminate fresh produce while it is being grown or harvested. Unlike many bacteria, the parasite can survive transportation from farms to grocery stores and eventually to consumers, making careful food preparation especially important.
Symptoms typically develop about one week after infection and may include:
Watery diarrhea
Loss of appetite
Weight loss
Stomach cramps or abdominal pain
Bloating
Increased gas
Nausea
Fatigue
Some individuals may also experience flu-like symptoms, while others may have no symptoms at all. Cyclosporiasis can be treated with specific prescription antibiotics when diagnosed by a healthcare provider.
Fresh Produce Can Be a Source
Health officials say Cyclospora has commonly been associated with fresh herbs and produce that are often eaten raw, including cilantro, parsley and certain fruits and vegetables.
Because contamination occurs where produce is grown rather than at grocery stores or restaurants, washing produce may reduce dirt and bacteria but may not completely remove the parasite. Cooking produce significantly lowers the risk of infection.
Public Health Investigation Continues
State and local health officials continue working together to identify possible sources of exposure. Most North Carolina cases have not been connected to a common ingredient, making investigations more challenging.
Buncombe County Public Health communicable disease nurses are working alongside healthcare providers, Environmental Health specialists and neighboring counties to monitor new cases, investigate illnesses and provide education to residents.
How to Reduce Your Risk
Buncombe County Public Health and the Centers for Disease Control and Prevention recommend the following food safety practices:
Wash hands thoroughly with soap and water before and after handling fresh fruits and vegetables.
Wash all fruits and vegetables under running water before eating, cutting or cooking.
Wash produce even if it is labeled "prewashed."
Cook produce whenever possible to significantly reduce the risk of illness.
Scrub firm fruits and vegetables, such as melons and cucumbers, with a clean produce brush.
Remove bruised or damaged portions before preparing produce.
Refrigerate peeled, cut or cooked fruits and vegetables within two hours.
When to Contact a Healthcare Provider
Residents experiencing severe or persistent diarrhea should contact their healthcare provider for evaluation and possible treatment.
"If you are experiencing severe or persistent diarrhea, you should reach out to your health care provider," said Buncombe County Public Health Director Dr. Ellis Matheson. "Taking steps to protect yourself and others includes washing your hands with soap and water before and after handling or preparing raw fruits and vegetables as well as washing all fruits and vegetables thoroughly under running water before eating, cutting or cooking."
Health officials encourage residents to remain informed, practice safe food handling and seek medical care if symptoms develop. Public health investigations into the recent increase in cases remain ongoing.
