Since May,a parasite-driven outbreak has impacted 34 U.S. states, with over 5,100 cases reported. Senator Jon Ossoff has criticized the Department of Health and Human Services for reducing the scope of the FoodNet surveillance program, which previously monitored eight pathogens.
5,100 cases and 34 states under threat
A widespread outbreak of cyclosporiasis is currently sweeping across the United States, affecting 34 different states. Cyclosporiasis is an intestinal infection caused by the Cyclospora cayetanensis parasite, which is typically contracted through contaminated food or water. As the report indicates, those infected often suffer from severe symptoms, including:
- Watery diarrhea
- Nausea and abdominal cramping
- Weight loss and fatigue
- Loss of appetite
While the exact source of this specific surge is still being investigated, the CDC has historically linked past oubtreaks to imported prduce such as raspberries, cilantro, mesclun lettuce, snow peas, and basil.
The July 2025 decision to slash FoodNet pathogens
The current public health crisis follows a significant shift in how the Foodborne Diseases Active Surveillance Network (FoodNet) monitors illnesses. According to the source, the program historically tracked eight different pathogens , but surveillance was reduced to just two in July 2025. The remaining focus of the program is now limited to Salmonella and Shiga toxin-producing E. coli.
The FoodNet program, which includes states such as Colorado, Connecticut, Georgia, Maryland, Minnesota, New Mexico, Oregon, and Tennessee, as well as parts of California and New York, justified the change by stating the surveillance landscape has evolved since the program's inception in 1995. The report notes that officials claimed the reduction would allow staff to prioritize core activities, though food safety experts had previously warned that such cuts could make it harder to track the prevaalence of foodborne illnesses.
Senator Ossoff’s critique of the Department of Health and Human Services
In a formal letter addressed to Kennedy, Senator Jon Ossoff accused the Department of Health and Human Services of undermining food safety. Ossoff characterized the reduction of critical public health programs as "foolish and self-indulgent," arguing that these decisions directly put American citizens at risk. The Senator also claimed that the Trump Administration is actively undermining food safety, noting the high number of cases across the U.S.
The missing details on the Cyclospora cayetanensis source
Despite the rising number of cases, several critical pieces of information remain unverified. The report does not confirm if the Department of Health and Human Services has responded to Ossoff's demands or if FoodNet has since restored the tracking of Cyclospora cayetanensis. Furthermore, investigators have yet to provide a definitive update on the specific source or the full scope of this nationwide outbreak.
