In September 2017, a feature page for One Health was included on the WHO website, defining One Health and highlighting important topic areas such as food safety, zoonotic disease, and antimicrobial resistance. The World Organization for Animal Health (OIE) headquartered in Paris, France. was also a partner in establishing a strategic One Health framework in 2008. The OIE works to maintain transparency surrounding global animal disease, collect and distribute veterinary information, publish international trade standards for animals/ animal products, improve veterinary services globally, and to promote animal welfare and food safety. The Food and Agriculture Organization of the United Nations (FAO) put forth in 2011 a strategic action plan for One Health, which had the objective to strengthen food security by improving animal production systems and veterinary services and called for action in improving collaborations between animal, human, and environmental health sectors.

CDC One Health Office The Centers for Disease Control and Prevention (CDC), created a One Health Office in 2009, becoming the first United States federal agency to have an office dedicated to this field. This office works alongside other animal, human, and environmental health organizations both within the United States and across the world in order to increase the awareness of One Health and develop tools to help strengthen One Health movements. The CDC One Health Office is involved with multiple initiatives, including working to implement a Zoonotic Disease Prioritization process, creating Global Health Security Agenda Action Packages, overseeing the Zoonoses Education Coalition, developing guidelines with the National Association of State Public Health Veterinarians, and helping educate youth involved with agriculture about influenza. Additionally, the CDC One Health Office hosts webinars to educate audiences about One Health issues such as food safety, antimicrobial resistance, and recent disease outbreaks. The One Health Zoonotic Disease Prioritization process is led by the CDC, holding workshops internationally to prioritize which zoonotic diseases are of the most concern and helping countries develop action plans to address those diseases.
