In a move that has drawn concern from public health professionals and worker safety advocates, the U.S. Centers for Disease Control and Prevention (CDC) under the Trump administration has instructed the National Academy of Sciences to cancel a long-planned workshop aimed at preventing human bird flu infections. The workshop, originally scheduled for June 26–27, was designed to provide expert discussion on the use of personal protective equipment (PPE) for those most at risk—including farmworkers and veterinarians.
The decision, confirmed by multiple sources and emails reviewed and reported by Reuters, was communicated to presenters earlier this week. According to an official advisory on the event’s website, the CDC terminated its contract for the workshop on April 23, 2025. As a result, all preparatory work ceased, and no final training products will be released.
The cancellation comes at a precarious moment. In the past year, 70 people—primarily agricultural workers—have been infected with avian influenza, a virus that has been spreading aggressively among poultry and, more alarmingly, cattle herds. The evolution of the virus in mammalian populations raises the stakes: adaptation could potentially lead to easier human-to-human transmission, a scenario public health experts have warned against for years.
Critical Knowledge Gap Left Unaddressed
The canceled workshop was intended to fill a well-documented gap in biosecurity training. According to Jenna Gibbs of the Ag Health & Safety Alliance, who was slated to present at the event, organizers were in “full planning mode” following requests from the farming community and a prior forum hosted in March.
PPE Failures Previously Linked to Infections
During a 2024 outbreak in Colorado, the CDC itself acknowledged that improper or inconsistent use of PPE was a contributing factor in human cases of bird flu. The planned workshop aimed to remedy this through evidence-based training, particularly focusing on proper PPE fit and usage for frontline workers.
Administrative Silence and Workforce Disruption
The Department of Health and Human Services (HHS), which oversees the CDC, has not provided a public rationale for the termination. Meanwhile, previous Reuters reporting has highlighted the strain on federal health agency staffing, with several departures affecting the continuity of the avian flu response.
Policy Shift Signals Deprioritization
While the Trump administration claims it is taking aggressive measures to contain bird flu through heightened farm biosecurity, the removal of expert-led education efforts suggests a broader shift away from transparent, community-based prevention strategies.
Voices from the Field
Gibbs emphasized the importance of this training for those on the front lines. “Farmers had requested this workshop. It was something the community wanted and needed,” she said. The event’s organizing committee included a cross-sectoral coalition of veterinarians, public health experts, and agricultural industry representatives, illustrating the wide recognition of its necessity.
Farmworker advocacy groups have also expressed dismay, underscoring that clear, accessible communication and hands-on training are essential to protecting vulnerable populations. In agricultural settings, where workers are often under-resourced and face language or cultural barriers, even basic PPE guidance can significantly reduce infection risks.
A Concerning Precedent
The cancellation of this workshop sets a troubling precedent in global health preparedness. At a time when zoonotic diseases like avian influenza are becoming more common due to increasing human-animal-environment interactions, halting educational and preventive measures undermines public health resilience. Without a coordinated and well-informed workforce, containment efforts are likely to falter when future outbreaks emerge.
While containment efforts such as farm-level biosecurity are important, they must be complemented by robust public health education, especially for those at highest risk of exposure. The CDC’s decision to terminate this workshop raises urgent questions about the administration’s commitment to transparency and evidence-based preparedness in the face of emerging infectious disease threats.
