WNCTimes News Desk -- August 2, 2026: The United States is experiencing the largest recorded Cyclospora outbreak in U.S. history, with thousands of confirmed illnesses and thousands more suspected cases under investigation. Public health officials continue working to identify all sources of contamination while monitoring new reports across dozens of states.
Cyclospora is a microscopic parasite that causes an intestinal illness known as cyclosporiasis. Symptoms typically begin about one week after exposure and commonly include prolonged watery diarrhea, stomach cramps, nausea, fatigue, loss of appetite, bloating, and weight loss. Without treatment, symptoms can last for weeks or even months. The illness is most often linked to contaminated fresh produce or water and is not commonly spread from person to person.
Federal Investigation Continues
Federal investigators have linked one major multistate outbreak to contaminated shredded iceberg lettuce imported from central Mexico. However, health officials emphasize that this represents only one part of the nationwide investigation. Additional Cyclospora outbreaks remain under investigation, and officials believe multiple contaminated food sources may ultimately be identified.
According to the latest available information, more than 6,700 laboratory-confirmed cases and more than 11,500 suspected cases have been reported or are under investigation across 45 states, making this the largest documented Cyclospora outbreak ever recorded in the United States. Hundreds of people have required hospitalization, although no deaths have been directly attributed to the outbreak.
North Carolina Cases Continue to Increase
North Carolina has experienced a sharp increase in reported illnesses this year.
Earlier this summer, the North Carolina Department of Health and Human Services reported 307 confirmed cases and 13 hospitalizations between May 1 and July 14. Since that report, state officials have continued documenting additional cases as the investigation has expanded.
Unlike some states where contaminated iceberg lettuce has been identified as a primary source, North Carolina investigators have not linked every illness to a single food item. During patient interviews, produce including parsley and cilantro has also been identified, suggesting more than one contaminated food source may be involved.
Western North Carolina
At this time, state health officials have not identified Western North Carolina as a separate outbreak hotspot. Cases have been reported throughout North Carolina, but no county-specific advisory has been issued for the mountain region.
Health officials continue encouraging residents to thoroughly wash fresh produce, practice good food safety habits, and contact a healthcare provider if they experience persistent diarrhea or other symptoms consistent with Cyclospora infection.
Questions Raised About Food Safety Resources
As the outbreak has continued to grow, some members of Congress have called for additional support for the nation's food safety system.
Lawmakers have urged the restoration of staffing and funding for agencies responsible for food safety inspections, disease surveillance, laboratory testing, and outbreak investigations, including the U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC).
Supporters of those requests argue that restoring personnel and resources would strengthen the nation's ability to detect, investigate, and respond to large foodborne illness outbreaks more quickly.
No Additional Hiring Announced
Federal agencies continue investigating the outbreak through existing resources, including traceback investigations, laboratory analysis, recalls, and coordination with state health departments.
As of this publication, federal agencies have not announced plans to hire additional food inspectors, epidemiologists, outbreak investigators, laboratory personnel, or other food safety staff specifically in response to the current Cyclospora outbreak.
The investigation remains active, and both the FDA and CDC expect additional cases to be identified as state health departments continue testing and reporting illnesses.
Health officials continue to advise consumers to stay informed, practice safe food handling, and follow any recall notices issued during the ongoing investigation.
