FDA halted FERN's Proficiency Testing Program, cutting pathogen-screening quality checks for 170 labs, citing staff cuts
On April 17, 2025, the FDA suspended the Proficiency Testing Program under the Food Emergency Response Network, which provided quality-control testing used by roughly 170 laboratories nationwide to screen for pathogens and contaminants, including Cyclospora in spinach and glyphosate residue in barley. The agency attributed the suspension to staffing shortages following earlier rounds of cuts.
