Health Officials Monitor Rising Cyclosporiasis Cases Across New York

As the summer season progresses, health authorities are tracking a widespread outbreak of cyclosporiasis, an intestinal infection caused by the *Cyclospora cayetanensis* parasite. According to data from the Centers for Disease Control and Prevention (CDC), the illness has been identified in at least 31 states, including New York.

Federal health officials issued a formal Health Alert Network notice earlier this month to address the uptick in domestically acquired cases. While the investigation remains active, some reports have pointed to fresh produce, particularly lettuce, as a potential vehicle for the parasite. Investigations into specific supply chains, including those involving major food service providers, are currently underway to determine the precise source of contamination.

Dr. Nate Wood, Director of Culinary Medicine at the Yale School of Medicine, recently emphasized the importance of distinguishing between legitimate health concerns and misinformation during the outbreak. In a discussion regarding the current situation, Wood noted that public confusion often arises from the complexities of food recalls and the potential for diagnostic errors. He advised that individuals experiencing persistent gastrointestinal symptoms should consult with healthcare providers to ensure accurate testing, as symptoms can sometimes mimic other common foodborne illnesses.

Cyclosporiasis is typically transmitted through the consumption of food or water contaminated with the parasite. Common symptoms include watery diarrhea, loss of appetite, weight loss, stomach cramps, bloating, increased gas, nausea, and fatigue. If left untreated, the illness can persist for several weeks or even months, often with symptoms that appear to improve and then return.

As of late July, the New York City Department of Health and Mental Hygiene has not issued specific localized guidance, though residents are encouraged to follow standard food safety practices, such as thoroughly washing fresh produce. Health experts continue to monitor the situation closely as they work to identify the specific food items linked to the current cluster of infections. Residents are advised to stay informed through official CDC updates and to contact their primary care physician if they suspect they have been exposed to the parasite.
