CDC (Surveillance of Cyclosporiasis)
U.S. federal public health agency
Background
Cyclosporiasis became a nationally notifiable disease in the United States in January 1999, and the CDC has conducted national surveillance for it since that point, relying on reports from state and local health departments. Active surveillance was also conducted through FoodNet (the Foodborne Diseases Active Surveillance Network), a collaborative program established in July 1995 among the CDC, the USDA's Food Safety and Inspection Service, the FDA, and 10 state health departments. The CDC's Division of Parasitic Diseases and Malaria (DPDM) was the primary organizational unit responsible for cyclosporiasis research and surveillance. In July 2025, under the second Trump administration, the CDC reduced the pathogens tracked by FoodNet from eight to two, making cyclosporiasis reporting optional rather than mandatory — ending roughly 28 years of systematic national tracking. The DPDM was subsequently dissolved as part of broader CDC reorganization and workforce cuts. By July 2026, a major cyclosporiasis outbreak had been reported across 31 states, with 843 domestically acquired cases recorded as of July 9, 2026 — raising public health concerns about the adequacy of the diminished surveillance infrastructure. The program's weakened state is widely attributed to the administration's budget reductions and agency restructuring rather than any editorial or political orientation in the surveillance data itself.
