North Carolina reports 69 Cyclospora cases as summer surge continues
The state health department has logged 69 Cyclospora infections since early June, mainly in Wake County, while the CDC investigates a multi-state outbreak affecting more than 140 people.
North Carolina health officials said 69 cases of cyclosporiasis have been reported since early June, with most infections occurring in Wake County, the state’s most populous area. The rise mirrors a broader investigation by the U.S. Centers for Disease Control and Prevention, which is tracking over 140 cases across 17 states and at least 20 hospitalizations.
Dr. Carl Williams, state public health veterinarian, told reporters that the current numbers do not meet the criteria for an outbreak. “We’ve had cases among all age ranges, including children and people over 65,” he said. “It is something that we would expect to pick up in June and July. It’s very likely that we will have more reports in the coming weeks.”
Cyclospora, a microscopic parasite transmitted through food or water contaminated with feces, typically spikes in the summer because it is often found on fresh produce consumed raw. Identifying the source can be difficult, as symptoms appear 2-14 days after exposure and patients may not recall specific foods. Williams noted that ingredients such as cilantro and parsley, which are frequently mixed into dishes, have historically been linked to outbreaks.
The state has strengthened its response after a 2024 incident that infected more than 130 people and was traced to a shrimp and parsley salad at several Wake County restaurants. A joint working group now coordinates food-history interviews, ingredient tracebacks and genetic testing of clinical specimens.
Health officials continue to advise thorough washing of fresh produce and proper cooking temperatures. “If you can remember one number, it’s 165 degrees Fahrenheit,” Williams said, adding that cooking to that temperature eliminates a range of foodborne pathogens. He also warned against leaving food in the 40°F-140°F “danger zone” during holiday gatherings.
People experiencing severe diarrhea or other gastrointestinal symptoms are urged to seek medical care. Diagnosis is made through stool testing, which also helps public health authorities track and investigate potential outbreaks.
