CDC narrowed mandatory FoodNet pathogen surveillance from eight diseases to two as it dissolved its parasitic-disease division
Effective July 1, 2025, CDC narrowed mandatory reporting under FoodNet -- its foodborne-disease surveillance collaboration with ten state health departments covering roughly 54 million people -- from eight tracked pathogens to two, making reporting on Campylobacter, Cyclospora, Listeria, Shigella, Vibrio, and Yersinia optional. The same year, CDC dissolved its Division of Parasitic Diseases and Malaria, the office housing the agency's Cyclospora and parasitic-disease expertise, reassigning remaining staff elsewhere. Public health researchers publicly disputed CDC's stated funding rationale and warned the changes would leave outbreaks harder to detect.
