CDC Lab Staff Cuts Threaten Vital Biological Samples

The recent staff cuts at the National Institute for Occupational Safety and Health (NIOSH) have raised serious concerns about the fate of thousands of biological samples crucial for occupational safety research. These samples, ranging from human urine to frozen rodent organs, are at risk of deterioration due to the lack of personnel to maintain them. The layoffs, which affected about two-thirds of the staff, were part of a broader restructuring plan announced by the Department of Health and Human Services (HHS). This plan involves moving NIOSH from the CDC to a new entity called the Administration for a Healthy America, resulting in the elimination of 10,000 full-time positions at HHS.

The biological samples, critical for understanding the impact of workplace exposures on health, are stored under specific conditions that require constant monitoring. For instance, some samples need to be kept at -112 Fahrenheit, while others are stored in liquid nitrogen. Without proper oversight, these conditions cannot be maintained, leading to the potential loss of invaluable research data. The samples include historical tissue samples, such as diseased human lungs from black lung victims, which are irreplaceable.

The layoffs have also disrupted ongoing research projects at NIOSH. These projects include studies on the effects of mustard gas on Gulf War soldiers, the impact of PFAS chemicals on pregnant workers, and the development of rapid toxicity tests for chemicals that US troops might encounter. The sudden halt in research activities not only delays scientific progress but also poses a risk to public health by slowing down the identification of workplace hazards.

The situation is further complicated by the lack of a clear plan for the custody and management of the samples and equipment left behind. Researchers are concerned about the potential destruction of samples and the abandonment of expensive instruments, which require regular maintenance to remain functional. The uncertainty surrounding the future of these resources underscores the need for a strategic approach to safeguard them.
