Today, I spent time diving into the global history of Bovine Spongiform Encephalopathy (BSE), also known as Mad Cow Disease. It was fascinating to compare how different countries responded to this major public health crisis that unfolded across the late 20th and early 21st centuries. I looked into the common patterns among nations—like banning specific risk materials (SRMs), prohibiting animal-based feed, and implementing disease surveillance systems. Almost every country initially underestimated the risk, which delayed proper responses. Eventually, most introduced stronger food safety systems and international cooperation guidelines based on OIE standards. But what really stood out were the differences in national strategies: The UK, where BSE originated, initially responded slowly, which led to widespread transmission. They later became a case study in how poor transparency can backfire in public health. Japan implemented extremely strict measures, like full-scale pre-slaughter testing for all cattle, even young ones, and a strong tracking system that helped regain consumer trust. The US focused on selective testing rather than full-scale inspections, relying more on risk management than prevention. South Korea had no domestic outbreak but faced massive public protests when it resumed US beef imports in 2008—making BSE a political issue rather than just a food safety concern. The EU took the most systematic approach, building institutions like the European Food Safety Authority (EFSA) and enforcing comprehensive traceability systems. It was also interesting to see how public perception and consumer trust varied by country. Japan regained trust through transparency and policy, while in Korea, distrust lingered despite scientific assurances. Learning about this made me think about how food safety issues can shape national policy, international trade, and even social movements. It’s more than just science—it’s about trust, governance, and communication. Definitely one of the more eye-opening case studies I’ve reviewed. I might dig into how BSE compares to the COVID-19 crisis next, especially in terms of crisis communication and public compliance.
