Inside Animal Research Labs: The Hidden Human and Animal Costs with Madeline Krasno | Ep12

What if the "necessary" animal research we rely on is breaking the people who conduct it?

In this episode of Puppies, Pandemics, and Public Health, host Dr. Johnny Lieberman speaks with Madeline Krasno, Executive Director of Justify and a former primate lab caretaker at UW Madison. Drawing from her two years caring for over 500 monkeys, preparing minimal "enrichment," administering meds, and witnessing daily stress and injuries. Madeline exposes the moral injury and compassion fatigue that plague lab workers. She shares how her experiences led to free speech lawsuits against UW Madison and the NIH, sparking national conversations on transparency. The discussion dives into systemic issues: stressed animals yielding unreliable data (with ~100% failure rates in human translation), lack of enforcement for violations, and the urgent need to shift toward animal-free technologies. Madeline also explains Justify's mission to support lab workers through confidential spaces, resources, and community-building to heal and advocate for change. This episode challenges assumptions about animal experimentation's validity and ethics, highlighting its links to human health, worker well-being, and public policy.

Top 3 Takeaways

• Lab Workers Face Profound Psychological Harm: Caretakers in animal research endure moral injury and compassion fatigue from witnessing suffering, with little support, highlighting that humans, too, pay a heavy price in this system.
• Animal Suffering in Labs Undermines Scientific Validity: Monkeys and other animals live in tiny cages under constant stress, leading to unreliable data; nearly 100% of experiments fail to translate to humans, questioning the necessity of such research.
• Enforcement and Transparency Are Severely Lacking: Violations like injuries or poor conditions often go unpunished with just "slaps on the wrist," while whistleblowers face retaliation—calling for better oversight and a shift to ethical, non-animal methods.
