While factory farming’s environmental footprint and animal welfare concerns have gained increasing attention, its devastating impact on human health and social justice remains surprisingly overlooked in policy discussions. From traumatized slaughterhouse workers to antibiotic-resistant superbugs, the effects of industrial animal agriculture ripple outward from the local to the global level. This system represents a multi-faceted threat to public health and social justice that demands urgent policy intervention.
The Toll on Workers’ Physical and Mental Health
Meat and poultry processing remains one of the most dangerous jobs in America, with injury rates more than twice the national average. Workers face physical hazards from sharp equipment, repetitive strain, and hazardous chemicals that linger in the air. These chemicals, including ammonia and hydrogen sulfide, can cause serious long-term respiratory problems.
The psychological toll is equally dire. While most of us never witness the horrors of factory farming, workers in these facilities endure traumatic experiences daily, which psychologists have identified as a unique form of PTSD. Known as perpetration-induced traumatic stress (PITS), it arises from being active participants in violence, even if involuntarily.
The mental health burdens in agricultural communities are widely acknowledged—recent UK parliamentary debates focused on labor struggles and economic uncertainty. Yet the role of factory farming in exacerbating these challenges remains conspicuously absent. Policymakers must ask: Can we address the mental health crisis in rural communities without confronting factory farming’s traumatic realities?
The Hidden Burden on Rural Communities
The American Public Health Association has twice called for a moratorium on new concentrated animal feeding operations (CAFOs)—the USDA’s term for factory farms—citing their devastating local impacts. CAFOs generate colossal amounts of waste, producing nearly 13 times more sewage than the entire U.S. human population.
This waste is often stored in open lagoons or sprayed onto fields, creating an environmental disaster. In North Carolina, a 1995 storm caused a lagoon rupture that released 22 million gallons of manure into the New River, killing millions of fish and contaminating water supplies. Such events remain frequent risks, especially as climate change fuels stronger storms.
Even under normal conditions, waste mismanagement leads to air and water contamination. Communities near CAFOs report elevated rates of asthma, gastrointestinal illnesses, and even depression linked to the overpowering stench. Marginalized populations, including low-income and minority groups, disproportionately bear these burdens, adding a grim layer of social injustice to the equation.
It’s Not Just Farmers and Local Communities—We’re All at Risk
Beyond its localized impacts, factory farming poses wider threats to public health. Cramped and unsanitary conditions in these facilities create ideal environments for pathogens to evolve and jump to humans. Since 1940, half of all new zoonotic diseases—including H1N1, swine flu, and mad cow disease—have originated from animal agriculture.
Perhaps the most alarming risk is the industry’s contribution to antimicrobial resistance. Around 75% of the world’s antibiotics are administered to livestock to counter the infection-prone conditions of industrial farming. This rampant overuse fuels the rise of antibiotic-resistant superbugs, which already claim 1.27 million lives annually. By 2050, these superbugs are projected to become the leading cause of death globally. The global poor bear the brunt of this escalating crisis, lacking access to advanced medical care.
Exacerbating Global Food Insecurity
Adding to these public health threats, factory farming paradoxically worsens global hunger. Currently, one-third of global crop calories are diverted to feed livestock, yielding only 12% of the calories consumed by humans. This inefficient system results in a net loss of 30% of global crop calories. In regions grappling with food insecurity, the diversion of vital resources to factory farming perpetuates hunger and inequality. A more sustainable and equitable food system would prioritize feeding people over livestock. Doing so would allow us to use the same amount of land to feed an additional 4 billion people.

The Need for Systemic Change
The evidence is clear: factory farming represents a systemic threat to public health and social justice. The costs of the status quo disproportionately burden disadvantaged communities—those who stand to gain the least from the industry.
Shifting to more humane farming practices would not only improve animal welfare but also create safer working conditions, healthier communities, and a more resilient food system. The question isn’t whether we can afford to transform our agricultural system—it’s whether we can afford not to.
While governments and corporationuns have been slow to act, the non-profit sector is making strides. Organizations worldwide are driving change through legislative campaigns, corporate accountability initiatives, and efforts to expand access to plant-based foods. These interventions not only reduce reliance on factory farming but also diminish public health risks by curbing intensive livestock production.
For those of us outside government or industry, supporting these non-profits is one of the most effective ways to catalyze change. The best charities are paving the way toward a more humane, sustainable, and equitable food system. Our support can help them finish what they’ve started.
