NIOSH Closure Signals Major Setback for Occupational Health​

We are deeply saddened to share that the recent federal restructuring has led to the closure of the National Institute for Occupational Safety and Health (NIOSH) which is a monumental loss for the field of occupational and environmental health.

Nearly 900 staff positions and a wide range of critical programs have been eliminated. For decades, NIOSH served as a cornerstone for worker health and safety, and its absence leaves a void that will be difficult to fill. Programs that have now ended include:​

  • Coal Workers' Health Surveillance Program – instrumental in identifying the resurgence of black lung disease in Central Appalachia.
  • Health Hazard Evaluation Program – essential in uncovering the causes of novel occupational lung diseases, including those linked to synthetic flavorings, flock, and indium-tin oxide.
  • National Personal Protective Technology Laboratory (NPPTL) – responsible for certifying the respirators used by workers, healthcare professionals, and the general public.
  • Groundbreaking research – NIOSH data informed OSHA and MSHA regulations to limit exposure to inhaled toxicants like silica, coal dust, and beryllium.
  • National Firefighter Registry for Cancer – the largest initiative aimed at understanding cancer risks among firefighters.
  • State-based surveillance support – vital in uncovering outbreaks of work-related diseases, such as artificial stone silicosis among California countertop workers.​
  • Training and extramural funding – key in developing the next generation of occupational health professionals and supporting critical research and outreach.​
