Encore Interview with Patsy Root
Episode 434
“Rules written in a panic rarely stand the test of time.”
In this encore episode, Trace Blackmore welcomes back Patsy Root, Senior Manager of Government Affairs at IDEXX Water and active member of the AWT Legislative and Regulatory Committee. Patsy brings global data, case studies, and clear recommendations for smarter Legionella regulation — and why a targeted focus on Legionella pneumophila can save both lives and resources.
From Outbreaks to Proactive Policies
Patsy unpacks a central truth: most regulations emerge reactively, often after a high-profile outbreak. Drawing on her research from the U.S., Canada, and Europe, she compares different jurisdictions’ approaches — from Quebec’s targeted testing mandate to New York City’s broader species-based rule — and reveals why some frameworks reduce cases far more effectively than others.
The Case for Targeted Testing
Legionella encompasses around 60 species, but not all carry equal risk. Patsy explains why L. pneumophila — the species most responsible for Legionnaires’ disease — demands priority in monitoring and control. Through examples from France, Germany, the UK, and beyond, she demonstrates how focusing on the pathogen itself, rather than all species, leads to measurable public health gains and cost savings.
Educating Lawmakers and Industry
Beyond technical data, Patsy emphasizes the importance of water professionals engaging with legislators. She outlines how clear communication, evidence-based recommendations, and standards like ASHRAE 188 can guide practical, enforceable rules. Her advice balances science with real-world feasibility, helping both regulators and facility managers protect health without unnecessary expense.
This conversation is more than a policy discussion — it’s a blueprint for better public health protection through smart, focused water management. Whether you work in compliance, operations, or advocacy, Patsy’s insights will equip you to engage in the legislative process with clarity and authority.
Stay engaged, keep learning, and continue scaling up your knowledge!
