Thousands of Urine and Tissue Samples Are in Danger of Rotting After Staff Cuts at a CDC Laboratory

Summary

Seven former federal workers have expressed concern over the fate of biological samples stored in a West Virginia laboratory after mass layoffs at the National Institute for Occupational Safety and Health (NIOSH). These samples, ranging from rodent organs to human tissue collected for research on job-related chemical exposure, require precise temperature control. With staff reductions, there are fears that liquid nitrogen levels could drop, leading to sample degradation or loss of viability. The Centers for Disease Control and Prevention has declined to comment on the samples' future, while some remaining employees have been told liquid nitrogen levels are being monitored. Destruction of these samples is also a possibility, involving incineration by a third-party company.

Federal workers warn of rotting biological samples as layoffs shutter key NIOSH lab. Seven staffers lost their jobs amid a Trump admin-led reduction in force at the National Institute for Occupational Safety and Health, raising concerns about thousands of delicate tissue samples, including diseased lungs and rodent organs, stored in precise conditions. Without constant monitoring, these irreplaceable materials—some dating back decades—could defrost, rot, or be destroyed. The agency’s relocation to a new entity under HHS adds further uncertainty for its future.

In West Virginia, seven federal employees who lost their jobs amid a workforce reduction at NIOSH are urging that thousands of biological samples—such as organs from rats and mice—might rot or be destroyed in the lab. Stored under extreme cold, these samples could become unusable unless maintained properly. Meanwhile, the restructuring plan moving NIOSH to AHA may impact not just jobs but also critical research and historical samples like black lung disease tissue.

Seven federal workers who lost their jobs recently are worried about thousands of biological samples—tissues from rats and mice—left behind at a West Virginia government lab. The samples, collected as part of studies into workplace chemical exposure, could rot or be destroyed unless properly stored. Some are kept in cold fridge, others in liquid nitrogen. If left unchecked, they might end up in a biohazard bag or incinerated.

The NIOSH researchers collected the tissue samples as part of experiments to determine how Americans may be impacted by chemicals and other substances they are exposed to at their jobs. Some of the samples are stored in a refrigerator that needs to be kept at -112 Farenheit at all times, while others are stored in liquid nitrogen. Unless someone inside the federal government continues to ensure the liquid nitrogen doesn’t totally evaporate, the samples will eventually defrost and begin to rot, according to three staff researchers who work with such materials. The Morgantown facility also houses historical tissue samples, including what the CDC describes as a “‘time capsule” of diseased human lungs from black lung victims. Current and former NIOSH employees who spoke to WIRED say they are not aware of any plans for these samples.
