The Cost of Cutting American Science: How Federal Cuts Diminish Public Health Capacity 

Among the federal government’s many responsibilities is the work it does to protect public health. Federal agencies monitor our food supply to ensure safety, conduct research to better understand emerging health threats, provide funding for public health programs in communities and work to detect and respond to disease outbreaks. Americans rely on these efforts every day—in a 2024 online survey, 74% of respondents said that “if the federal government issued safety guidance about food you eat regularly,” they would follow it.

Changes to Federal Public Health Capacity

The Trump administration’s efforts to reshape the federal government have resulted in significant impacts on our nation’s public health capacity over the past 20 months, affecting the response to health concerns such as measles, Ebola and cyclosporiasis.

Agencies with core public health, food safety and disease prevention responsibilities experienced large workforce decreases during the first year of the administration. At the Centers for Disease Control and Prevention, for instance, the workforce in February 2026 was 26.7% smaller than in September 2024 before the start of the Trump administration. The Food and Drug Administration saw a similarly steep decline of 21.6%. Agencies such as the National Institutes of Health, Substance Abuse and Mental Health Services Administration and Food Safety and Inspection Service also experienced large workforce decreases.

Changes can also be seen in crucial public health occupations. The number of federal food inspectors, for example, decreased by more than half between September 2024 and February 2026, going from 1,035 to 473. This is the lowest number of food inspectors employed by the federal government since at least 2005. By February 2026, there were also 33.3% fewer federal public health program specialists, whose work includes advising federal funding recipients on public health activities and analyzing the effectiveness of public health programs. Government’s capacity is diminished as employees with specialized knowledge and experience in protecting the public and responding to health risks depart, leaving agencies less prepared to carry out their public health missions.

There also have been vacancies in critical high-level leadership positions at public health agencies, most notably at the CDC, which had a permanent Senate-confirmed director for less than a month between January 2025 and early August 2026. Although the CDC has previously been led by acting directors at the start of an administration, the nearly yearlong gap since the departure of the administration’s first permanent director in August 2025 is without precedent. As of August 2026, the FDA is also currently without a Senate-confirmed commissioner following the previous commissioner’s resignation in May 2026.

Additionally, public health agencies are experiencing increased politicization of their leadership ranks. In agencies such as the CDC and Food Safety and Inspection Service, the number of individuals in the Senior Executive Service—the most senior career leaders in government—has declined significantly, while at the same time the number of political appointees has reached record levels.

At the CDC, for example, the number of career SES decreased 42.9% between December 2024 and February 2026, while the number of non-Senate confirmed political appointees at the agency was six times larger than the agency’s historical average from 2009 and 2024. Knowledgeable career leaders are integral to the ability of public health agencies to carry out their work with scientific integrity and professional judgment, and rapid leadership turnover and increased politicization threaten agencies’ ability to make evidence-based decisions to protect our health.

The upheaval and politicization in public health agencies have also negatively affected employee engagement. Strong employee engagement is crucial to the ability of agencies to carry out their mission and successfully provide essential services to the public. In the 2025 Public Service Viewpoint Survey conducted by the Partnership for Public Service, the Department of Health and Human Services—which encompasses major public health agencies such as the CDC and FDA—had an employee engagement and satisfaction score of 20.4 out of 100, one of the lowest among large agencies. Only 2.8% of HHS employees indicated trust in their political leaders and only 8.7% reported confidence that they could report a suspected violation of law or regulation without retaliation. Employees at HHS also reported that the agency’s ability to provide services to the public had suffered. Nearly half of employees at HHS, 47.5%, said their work unit was worse at delivering quality services compared to its performance in 2024. In addition, 57.8% said their work unit was performing worse at fulfilling stakeholder needs.

In addition to the work done within federal agencies, the federal government also distributes significant funding for public health and disease prevention work to state and local governments, nonprofits and small businesses—funding which has been significantly disrupted. At the CDC, for example, there was a 71.9% decrease in the amount of project grant funding issued in fiscal year 2025 compared to fiscal year 2024. The FDA also issued far less funding in fiscal year 2025—a 21.3% decrease from its fiscal year 2024 funding. Changes in federal funding include the ending of grants to community organizations that worked on HIV prevention and the cancellation of funding for research into improvements to patient safety and healthcare quality.

These changes go beyond federal agencies to impact the broader public health ecosystem, including the state and local health departments responsible for much of the on-the-ground public health work in their communities. About 80% of the CDC’s domestic funding is directed towards state and local partners—meaning that cuts to CDC funding can ultimately result in cuts to state and local public health capacity. Federal agencies also provide expertise and assistance to state and local health agencies as they deal with particular health challenges, but workforce cuts have resulted in fewer federal employees available to help.

The Impact of Changes to Public Health Capacity

These changes to federal public health capacity are not abstract concerns. Disrupted programs, reduced funding and lost expertise at public health agencies across all levels of government threaten the public’s physical well-being and safety. In some cases, this has already led to harm.

The most immediate impacts of federal cuts were seen in interruptions to ongoing public health programs and crisis responses. In one instance, when CDC grants were canceled during the 2025 Texas measles outbreak—the most severe measles outbreak in 25 years—public health officials in Lubbock, Texas were forced to pause parts of their measles response work supported by the frozen funding. Lubbock’s director of public health further said that a lack of available CDC experts to reach out to for advice “definitely” impacted the department’s response to the measles crisis. Cuts to federal funding also forced Dallas County Health and Human Services to cut staff and cancel 50 community vaccination clinics during the outbreak.

Public health work outside of major outbreak responses was also disrupted. For example, in April 2025, the Milwaukee Public Health Department was unexpectedly unable to reach experts on lead poisoning due to firings at the CDC when responding to concerns about lead contamination in Milwaukee public schools. Due to federal workforce cuts, several programs at the CDC, including Alzheimer’s and epilepsy programs, have also become trapped in limbo—existing on paper, but without the staff necessary to operate.

More recent crises reveal how federal cuts have weakened the public health infrastructure needed to prevent and respond to dangerous new outbreaks. Internationally, cuts at the U.S. Agency for International Development eliminated funding for disease testing and contact tracing abroad, which delayed detection of and responses to the 2026 Ebola outbreak in the Democratic Republic of Congo. While international outbreaks may seem far removed, the unchecked spread of disease in any country can quickly pose a danger to economic well-being, security and health around the world.

Within the United States, public health cuts inhibited responses to the summer 2026 outbreak of the food-borne parasite cyclospora. At the federal level, cuts to funding for lab equipment and for CDC staff with expertise in parasitic infections—including 9 out of 11 staff members at the lab responsible for identifying parasitic outbreaks in 2025— contributed to the largest reporting delay in outbreak cases at the CDC in 15 years. Conflicting communications from the FDA about the source of the outbreak, which followed cuts to the agency’s communications department, additionally led to confusion among the public about how to best avoid infection. At the same time, cuts to HHS funding and support for local and state public health slowed some health departments’ responses to the crisis.

The exact costs of these delays, constraints and confusion in public health responses are difficult to estimate. However, their message is clear: federal cuts have already made containing threats to public health even more of a challenge.

Conclusion

Protecting public health—from food safety to disease prevention—is one of the federal government’s most important missions. Dramatic and haphazard cuts to federal agencies and funding have already disrupted the public health system, impacting the response to challenges such as measles, lead poisoning and cyclosporiasis.

The U.S. public health system needed improvement before these disruptions. Since 2022, federal leadership and coordination in response to public health outbreaks has been on the Government Accountability Office’s High-Risk List of areas in need of attention to improve government effectiveness and efficiency. Recent cuts only compound these concerns.

The chaotic dismantling of government and resulting disruptions to crucial functions like public health and disease prevention highlight the need for meaningful reform and concrete policy proposals to reimagine how government can better serve the public and be more effective, responsive and accountable.
