A large cyclospora outbreak has renewed debate about how the United States detects foodborne illness. KFF Health News reported that food-safety experts are concerned federal public-health cuts and changes to surveillance could make future outbreaks harder to identify.
The CDC’s FoodNet network once required participating states to track several pathogens, including cyclospora, listeria and campylobacter. KFF reported that some mandatory reporting requirements have been curtailed, while the Department of Health and Human Services says other surveillance systems remain in place and that CDC monitoring of cyclospora continues.
The stakes are higher for pathogens such as listeria, which can cause severe illness and death. Experts said passive reporting depends on states submitting information promptly, and gaps can delay recognition of a common source.
The current outbreak has sickened thousands, according to CDC data. Public-health officials continue to investigate cases and possible food sources while agencies debate how best to maintain national detection capacity.
