Commentary: The devastating legacy of Canada's Mad Cow Crisis

The Mad Cow Crisis started 20 years ago this week. For most Canadians, May 20, 2003, means little. But for the beef industry, the situation was nothing less than dreadful. It brought devastation, bankruptcies, and broken families. It was a nightmare.

On May 20, 2003, the Canadian Food Inspection Agency declared that a black Angus cow originating from northern Alberta had been detected with bovine spongiform encephalopathy (BSE), also known as Mad Cow disease. In response, the United States promptly imposed a ban on Canadian beef and cattle imports, leading to approximately 40 other nations taking similar measures.

Mad cow disease is a fatal illness that gradually deteriorates cattle’s brain and spinal cord. Although humans cannot contract mad cow disease, there is a rare possibility of developing a human variant called variant Creutzfeldt-Jakob disease (vCJD), which is also fatal. Over time, vCJD causes degeneration of the brain and spinal cord. According to the U.S. Centers for Disease Control and Prevention, more than 500 Americans die every year exhibiting symptoms that match those of the disease. An autopsy is required to properly diagnose the disease.

In this CEOs of the Industry – International Edition, we sit down with Michael Agerley, Partner at IQinAbox, to explore how data is reshaping the future of pig production.

After more than 20 years as a veterinarian, Michael shares his unique perspective on the shift from hands-on animal care to data-driven decision making across the pork value chain.

We dive into:

• How better data is improving real on-farm decisions

• The biggest opportunities still untapped in pig production

• How Europe is leading (and where it’s still lagging) in tech adoption

• The role of AI and smart systems in the next 5–10 years

• Why trust, leadership, and practical application matter more than ever

This conversation bridges veterinary insight, technology, and real-world farming, offering a clear look at where the industry is headed—and what it will take to get there.
