What significant challenge prompted the creation of OIE?

The establishment of the World Organisation for Animal Health (OIE) was largely motivated by the need to address animal health issues on a global scale, particularly highlighted by the rinderpest outbreak in Europe. Rinderpest, a highly contagious viral disease affecting cattle and other animals, posed a significant threat to livestock populations and food resources. The devastating impact of this disease underscored the necessity for international collaboration and the establishment of standardized protocols to manage animal diseases. This led to the formation of the OIE, which focuses on improving animal health, ensuring food safety, and combating the spread of animal diseases globally. Thus, the response to the rinderpest outbreak was pivotal, driving the need for a coordinated international body to protect animal health and, by extension, food security. The other options, while relevant global issues, did not directly catalyze the OIE's formation in the same way that the rinderpest challenge did.
