Health officials are currently managing a rise in cyclosporiasis cases this summer, though experts urge the public to maintain a balanced perspective regarding the risk of contracting the illness. While some regions report higher-than-average figures, public health authorities emphasize that the situation is not uniform across the country, and in many instances, no single source for the infections has been identified.
Understanding the Current Case Trends
While national headlines may suggest a widespread food safety crisis, public health data paints a more nuanced picture. According to Consumer Reports, the surge in cyclosporiasis—an intestinal infection caused by the Cyclospora cayetanensis parasite—is not affecting every state equally. In several states, including California, Massachusetts, and Minnesota, case counts remain at or below typical seasonal levels. Amy Barrett, a spokesperson for the Minnesota Department of Health, confirmed that while 66 cases have been reported in that state since May 1, none were linked to the multistate outbreaks being tracked elsewhere.
In other regions, the numbers are higher but remain within expected bounds. Marissa Crary, a spokesperson for the New York State Department of Health, stated on July 17 that preliminary data indicates approximately 576 cases of cyclosporiasis have been reported in New York since May. Because the state typically records between 500 and 700 cases per year, Crary noted that current statewide cases do not represent a major deviation from the norm.
Illinois has also seen elevated numbers, recording 355 cases as of July 20. Matthew Mata, a spokesperson for the Illinois Department of Public Health, told Consumer Reports that while this total is higher than average,
only 180 of those cases appear to have been domestically acquired, as cyclosporiasis is commonly contracted while traveling abroad. Mata added that no single source or cause of this increase has been identified, and there is no evidence of a large outbreak accounting for all or most of these cases.
The Investigation Challenges in North Carolina
North Carolina has become a significant focal point for the recent spike. According to state data, North Carolina has reported 561 cases since May, with 254 new cases reported since the last update on July 14. The cases are spread across the state, with the majority concentrated in Wake County. The Wake County Health Department reports that the county total has reached 366 cases, reflecting an increase of 16 cases from a previous update.
Dr. Carl Williams, State Public Health Veterinarian for the North Carolina Department of Health and Human Services (NCDHHS), clarified that the increase is considered an outbreak. You could say that it would be statewide outbreak like a lot of other states are seeing,
Williams said. Usually we like to say we've identified a source when we call something an outbreak, and we just don't have that yet. But, clearly there are sources out there.
While the U.S. Centers for Disease Control and Prevention (CDC) is tracking more than 1,500 cases across five states and has linked those specific cases to shredded iceberg lettuce served at Taco Bell, NCDHHS officials suggest that in North Carolina, lettuce is likely not the sole culprit. Our thought is that it’s likely, maybe probable, that there are multiple vehicles, Williams stated. It's not a single source or a single food product from a single company.
This ambiguity is common in foodborne illness investigations. Because symptoms of cyclosporiasis often appear 2 to 14 days after exposure to contaminated food, patients frequently struggle to recall their specific food history by the time they seek medical care. Dr. Christopher Chao, WakeMed Urgent Care Medical Director, noted the difficulty in narrowing down a source, stating, Most patients don't get sick for at least a week, and by the time we interview them, and by the time we try to identify the source, no one can really remember where they ate or what they ate.
Nutrient-Dense Foods and Safety
Despite the challenges posed by foodborne illnesses, experts advise against removing fresh produce from a healthy diet. Vegetables like beetroot are cited for providing essential nutrients such as folate, potassium, iron, and vitamin C. According to a 2017 study published in the Journal of Physiology – Heart and Circulatory Physiology, dietary nitrate found in beetroot juice helped dilate blood vessels to decrease blood pressure, which is a leading factor in heart attack risk. Lifestyle coach Luke Coutinho has also emphasized the importance of high-fiber, anti-inflammatory vegetables in a daily diet.
Because the source of an outbreak can take weeks or months to determine, consumers are encouraged to focus on standard food safety practices. If you are concerned about symptoms or recent food consumption, consult a qualified medical professional to discuss whether diagnostic testing is appropriate for your specific health situation.
