Introduction
When most people hear animal welfare, they think about ethics—preventing cruelty, ensuring humane treatment, and protecting rights. While these concerns are vital, the reality is much broader. Animal welfare and public health are deeply interconnected: how we treat animals shapes food safety, disease prevention, climate change, and even global health security.
So, is animal welfare only about compassion, or is it also about saving human lives?
Why Animal Welfare Matters for Human Health
Animal welfare has direct consequences for people. Poor conditions in farms, markets, or wildlife trade systems create environments where diseases spread quickly. Indeed, the World Health Organization estimates that 60% of emerging infectious diseases are zoonotic, meaning they jump from animals to humans [1]. Moreover, from avian influenza to COVID-19, compromised animal care has been a major driver of outbreaks.
The 2003 SARS outbreak, for example, was traced to wildlife markets where stressed and poorly treated animals created a breeding ground for viruses. Similar conditions have fueled swine flu and avian influenza epidemics, illustrating how inadequate welfare standards can destabilize global health security.
Beyond infectious disease, poor welfare reduces food quality. For example, livestock raised in overcrowded and unsanitary environments often require heavy antibiotic use, fueling antimicrobial resistance (AMR). AMR now threatens to cause 10 million human deaths annually by 2050 if left unchecked [2].
Food Safety and Consumer Trust
The way animals are treated directly influences the safety of the food we eat. When they are sick or stressed, animals are more prone to infections, which can enter the food chain. As a result, contaminated meat, eggs, or dairy not only cause foodborne illness but also erode consumer trust in global food systems.
Furthermore, improving welfare—through better housing, veterinary care, and reduced antibiotic misuse—creates healthier animals and safer food. This is why researchers and international agencies emphasize that welfare standards are not just ethical guidelines but essential for food security and international trade [3][4].
Environmental and Climate Connections
The link between how animals are treated and environmental sustainability is strong. Intensive livestock production contributes significantly to greenhouse gas emissions, deforestation, and water pollution. At the same time, stressed or overbred animals demand more resources while yielding less efficient results in food systems.
By contrast, welfare-centered practices—such as pasture-based systems, humane handling, and better nutrition—support both climate goals and ecosystem health. By improving animal welfare, we also advance the One Health approach, where human, animal, and environmental wellbeing are inseparable [5].
Social and Economic Dimensions
Communities benefit economically from strong animal welfare systems. Farmers who adopt humane and sustainable methods often produce higher-quality goods, access better markets, and experience fewer disease outbreaks that could devastate livelihoods.
In many low- and middle-income countries, livestock is not just food but financial security. For instance, in parts of East Africa, programs that train farmers in humane husbandry have reduced animal mortality, boosted milk yields, and stabilized family incomes. These initiatives demonstrate that animal welfare directly contributes to poverty reduction and resilience.
Therefore, protecting animal welfare strengthens resilience, helping families and communities survive climate shocks, epidemics, and economic downturns.
A One Health Perspective on Animal Welfare and Public Health
A One Health perspective reveals animal welfare as a public health strategy—not just an ethical obligation. Healthy animals mean safer food, fewer zoonotic spillovers, reduced antimicrobial resistance, and a cleaner environment.
Consequently, by addressing welfare, policymakers can simultaneously advance human health, protect ecosystems, and achieve sustainable development goals. This integrated view explains why animal welfare belongs in public health agendas, climate negotiations, and economic planning—not only in animal rights campaigns.
Conclusion
Animal welfare is more than compassion—it’s prevention, protection, and progress. From safeguarding food systems to curbing disease outbreaks and reducing emissions, the way we treat animals shapes the health of our societies.
Recognizing the link between animal welfare and public health transforms the debate: it is no longer just an ethical concern, but a global survival strategy. Humane treatment of animals means healthier communities, stronger economies, and a more sustainable future.
For policymakers, this means embedding welfare standards in agricultural and health regulations. For consumers, it means supporting food systems that value humane treatment. For scientists and advocates, it means making welfare a visible part of the global health conversation.
