Michael LeBlanc and Sylvain Charlebois explore Canada’s evolving agri-food landscape, from renewed trade with China and Davos policy signals to alarming food inflation trends. The episode’s centerpiece is an interview with Deleo de Leonardis, CEO and Co-Founder of Purity IQ, who explains why basic identity testing is no longer enough to protect consumers from food fraud. Advanced authenticity testing, she argues, is becoming essential for trust in global food systems.
In this episode of The Food Professor Podcast, hosts Michael LeBlanc and Dr. Sylvain Charlebois unpack two powerful and timely themes shaping Canada’s food system: the shifting geopolitical landscape of agri-food and the growing threat of food fraud. The episode opens with a wide-ranging news segment focused on Canada’s evolving trade relationship with China, recent developments at Davos, and new data on food inflation.
Sylvain shares insights from Manitoba Ag Days, where optimism is building among farmers following Canada’s short-term agricultural trade deal with China, particularly for canola, lobster, and beef exports. The hosts explore the strategic implications of re-opening Chinese markets, noting how geopolitical uncertainty is now a permanent feature of food systems. Sylvain argues that Canada must invest more heavily in domestic manufacturing, modernize supply management, and incentivize green technologies to strengthen long-term food sovereignty. The conversation also turns to food inflation, with Sylvain explaining why Canada’s 6.2% food inflation rate cannot be blamed solely on the GST holiday, pointing instead to opportunistic pricing and structural inefficiencies across the supply chain.
The second half of the episode features a compelling interview with Deleo de Leonardis, CEO and Co-Founder of Purity IQ, a science-based company specializing in food and supplement authenticity testing. Drawing on her 30-year career in grocery retail, including two decades at Sobeys, Deleo explains how food fraud represents one of the most underestimated risks in modern retail. While many companies rely on basic identity testing, Deleo highlights the critical difference between identity and authenticity: a product may technically meet regulatory standards while still being diluted, substituted, or adulterated.
Deleo introduces advanced tools such as nuclear magnetic resonance (NMR) spectroscopy and DNA-based testing, which allow for non-targeted analysis at the molecular level. This approach enables Purity IQ to detect unknown adulterants and inconsistencies across batches—something traditional testing methods often miss. She outlines high-risk categories such as olive oil, honey, fish, avocado oil, sesame oil, and dietary supplements, emphasizing that food fraud is an opportunistic crime driven by global supply shocks, climate events, tariffs, and geopolitical instability.
Together, the episode paints a sobering picture: as supply chains become more complex and economic pressures rise, food authenticity will become a defining issue for retailers, brands, and regulators alike. The hosts conclude that in an era of shrinking trust and rising prices, transparency and scientific verification may be the only sustainable path forward for the global food industry.
