Lessons From a Homicide Detective

Why Foodborne Illness Investigations Must Follow the Evidence

A Perspective from Rod Wheeler, MPA

CEO, Global Food Defense Institute (GFDI)  |  Former Washington, D.C. Homicide Detective

As a former Washington, D.C. homicide detective, I learned early on that the truth doesn't reveal itself on anyone's timeline — it has to be uncovered, methodically, one piece of evidence at a time. That lesson has stayed with me throughout my career in food defense. In this article, I share how the same investigative discipline that guided my homicide cases applies directly to foodborne illness investigations like the recent Cyclospora outbreak — and why following the evidence, not assumptions, is the only way to get it right.

Over the course of his career, he has advised government agencies, Fortune 500 corporations, and critical infrastructure organizations on how to identify vulnerabilities, harden operations, and build lasting resilience.

For more than a decade, he brought that same expertise to a national audience as a Senior Law Enforcement & Crime Analyst for Fox News Channel, translating complex security and criminal justice issues for the public.

In 2015, he founded The Global Food Defense Institute, an international consulting and training organization that has since conducted more than 500 physical security and food defense vulnerability assessments for corporate and government clients. He is the author of Food Defense: From Regulation to Reality — Creating a Real World Culture of Safety, Security & Preparedness, and he remains an active international keynote speaker and executive instructor, regularly training the next generation of security and food defense professionals.

Whether advising a Fortune 500 boardroom, training frontline staff, or leading a federal coordinating council, he brings the same standard: protect people, protect brands, and build organizations that can withstand what comes next.
