Environmental Health Monitoring Presentations
The 3Rs Collaborative’s EHM Initiative and other key stakeholders have organized a number of presentations about rodent health monitoring and replacing soiled bedding sentinels with environmental health monitoring.
Presentation Showcase: 2025 Poster

Presentations
- AALAS 2025 – Environmental Health Monitoring: Evidence, Quarantine, Outbreaks, and Positive Findings
- In this session, presenters present on (1) Using EHM in rodent quarantine as a replacement & refinement (2) how to troubleshoot outbreaks with unique challenges in immunodeficient rodent populations monitored by EHM, and (3) how to address positive PCR results with EHM
- WC13 2025 – No More Canaries in Coal Mines: A Systematic Review of Environmental Health Monitoring
- UFAW 2025 – No More Canaries in Coal Mines: A Systematic Review of Environmental Health Monitoring
- FELASA 2025 – No More Canaries in Coal Mines: A Systematic Review of Environmental Health Monitoring
- AALAS 2024 – Pushing the Boundaries of Environmental Health Monitoring: What’s Next
- In this sessions, presenters present on (1) an overview of the EHM systematic literature review, (2) detection & origin of LDV by EHM, (3) detection and elimination of P. murina by EHM, (4) EHM for other rodents & unexpected false positives, and (5) EHM and the role of the IACUC.
- AALAS 2023 – Environmental Health Monitoring: A Holistic Approach for All Housing Types
- In this session, 5 presenters discussed updates from the 3RsC EHM systematic review, research & case studies from 3 varied institutions with mixed house, 3RsC resources, and a brief note on a recently published article.
- Responsible Research in Practice 2023 – Guide to Environmental Health Monitoring
- During this session, Dr. Kerith Luchins (Director of Rodent Clinical Services, University of Chicago) discussed a systematic review of the scientific evidence behind environmental health monitoring (EHM) and shared her experience of implementing EHM as a replacement for rodent sentinels. Specifically she discussed:
- – why research institutions are increasingly replacing their soiled bedding sentinel rodents with environmental health monitoring (EHM);
– a systematic review of the scientific evidence behind EHM;
– common challenges and solutions including options for racks that have cage level filtration;
– free resources developed to support facilities to implement this replacement. - AALAS 2022 – Making the Switch to Environmental Health Monitoring: Evidence, Data, & Practicalities
- Systematic review evidence for environmental health monitoring
- Benchmarking, barriers, & solutions for environmental health monitoring
- Sentinel free soiled bedding sampling
- Academic perspectives on making the switch across caging types
- Industry perspectives on making the switch across sites & caging types
- AALAS 2021 – Switching to Environmental Health Monitoring for Rodents; How, Why & Will It Cost More
