The era of the small family farm has all but disappeared. Industry marketing still leans on pastoral images of red barns and animals grazing in open fields, but that imagery no longer reflects how meat is produced in the US. Today, fewer than 1 percent of farmed animals are raised outside factory farms. This means almost all meat comes from conditions that bear little resemblance to what the packaging promises.

As that idyllic model has declined, so has the practice of raising animals in smaller numbers under higher-welfare conditions. Production is now concentrated in factory farms known as Concentrated Animal Feeding Operations, or CAFOs. These industrial operations confine hundreds, thousands, or even hundreds of thousands of animals in a single facility. And with them comes a tidal wave of waste.

The US Department of Agriculture (USDA) estimates that US livestock and poultry generate up to 1.4 billion tons of manure each year, enough to fill more than 500,000 Olympic swimming pools. CAFOs alone account for roughly 369 million tons of this total, about 13 times the sewage produced by the entire US population, according to the American Public Health Association.

At these volumes, the question is: who is legally responsible for the waste? In most areas of law, liability follows control. Those who generate pollution are expected to manage it and bear its costs, whether commercial, industrial, or municipal. Industrial animal agriculture does not follow this rule. And that exception is built into the meat industry’s design.

Inside the System

A handful of corporations dominate modern meat production. The four largest firms control roughly half of all US livestock output, with concentration even higher in beef at about 85 percent, and somewhat lower in pork and poultry. This structure, in which a single company oversees every stage from birth to slaughter, is called vertical integration. The companies themselves are known as “integrators.”

Most animals raised for food in the US are not owned by the farmers who raise them. The integrator owns them. The farmer, known as a “grower,” provides the land, barns, labor, utilities, and financing for the facilities. The integrator tightly controls production. It supplies the animals, feed, and medication and sets the production schedule. It also determines stocking densities.

The grower starts from a structural disadvantage, bound by contracts they have little power to change. According to a Farmers’ Legal Action Group analysis of livestock production contracts, growers are typically required to hold all environmental permits and to “defend, indemnify, and hold harmless” the integrator from pollution liability, including manure management and field application. Responsibility for the waste attaches to the farmer, even though the integrator makes the decisions that determine its volume.

These contracts also leave growers exposed. Many take on significant debt to build and maintain the facilities required by their contract. Meanwhile, consolidation in the meat industry narrows growers’ options. In many regions, there are few, if any, alternative buyers. USDA research found that half of contract chicken producers have only one or two integrators in their area. Refusing an integrator’s terms can mean losing the only available contract. Growers have almost no leverage.

This arrangement is often described as reducing financial risk for growers by removing ownership of the animals. But it also shifts the costs of confinement onto farmers, while the integrator retains control over production. That authority sets the scale of operations, and with it, the amount of waste the system inevitably produces.

Where the Waste Goes

Manure disposal typically involves storing liquid waste in open lagoons or pits, then spraying it onto nearby fields as fertilizer. Under permit-required nutrient management plans, manure must be applied at rates crops can support. At modern CAFO production levels, that volume often exceeds what surrounding land can safely absorb. Even with these requirements, application limits are frequently exceeded, with manure spread beyond agronomic need, increasing the risk that excess nutrients run off nearby waterways or seep into groundwater.

But what happens when facilities produce more manure than can be applied locally? To avoid violations, operators move excess manure off-site, often recorded as “distribution and utilization” or reflected as little to no on-site application. Researchers refer to this as “manifesting,” a term borrowed from hazardous waste regulation. Environmental Protection Agency (EPA) rules require permitted CAFOs to document manure transfers and recipient information. But once the waste leaves the facility, no federal system tracks it. Responsibility shifts away from the source, and the pollution is relocated rather than addressed.

As these operations concentrate, the problem intensifies. More animals mean more waste. Nowhere is this more apparent than in Duplin County, North Carolina, which has one of the highest concentrations of industrial hog operations in the US. There, hogs vastly outnumber people, with about 2.2 million pigs in a county of just over 50,000 residents.

At these densities, waste exceeds local land capacity.

Researchers at the USDA have acknowledged that it would be “virtually impossible” for nearby land to fully absorb the waste generated in areas with such high concentrations. The same analysis notes that the high cost of transporting manure leads to overapplication on nearby land, even where crops cannot absorb the excess nutrients. This suggests that production levels may exceed what can be lawfully managed under permit requirements.

Still, the waste must go somewhere. It either accumulates on nearby land or moves beyond effective oversight. Either way, environmental capacity has already been exceeded. At current stocking densities, this level of pollution is expected, not incidental. As the industry plans further expansion, production already outpaces what the environment can sustain.

Living Next to It

Life near a CAFO is shaped by persistent exposure to its effects.

Most immediately, the odor is constant and permeates daily life. Residents weigh whether to open a window or step outside. Many describe feeling confined to their homes, their quality of life diminished by the air outside.

This is not just a matter of discomfort. People living in these areas report higher rates of respiratory and gastrointestinal illness, along with headaches, coughing, and eye and throat irritation.Children, the elderly, and people with pre-existing conditions face elevated risks from CAFO exposure, including respiratory illnesses such as asthma. At its most severe, exposure has been linked to higher infant mortality from air pollution.

The impact is also economic and social. Communities downwind of these operations face declining property values. And that burden does not fall evenly. Nearby communities are disproportionately low-income and minority, a pattern researchers and advocates have documented. The film The Smell of Money traces this pattern, following rural North Carolina residents—particularly Black, Latinx, and Indigenous communities—as they challenge what has been identified as environmental racism in the industrial hog industry.

The same harms extend into the surrounding environment.

When manure is overapplied, the excess must go somewhere. Often, this excess manure ends up polluting local waters, as rainfall and irrigation carry it into ditches, streams, and rivers, leading to algal blooms, oxygen-depleted “dead zones,” and fish kills. Even where operations meet permit requirements, these outcomes persist.

As long as animals continue to be raised this intensively, excess waste is inevitable. The industry has expanded by keeping more animals in less space at lower cost. This has led to today’s system: hens in cages too small to extend their wings, breeding sows in stalls too narrow to turn around, and cattle crowded into feedlots. In the drive to produce cheap and abundant animal products, animal welfare has been an afterthought.

But waste and welfare are not separate problems. How many animals are confined, and how they are housed, determines how much waste they produce. When operations generate more waste than can be lawfully managed, the issue is not waste management but production at current densities. And if that level of output results in persistent pollution, the issue is scale. The industry’s current trajectory is expansion, based on the assumption that its impacts can be managed downstream. But if production already exceeds legal limits, expansion moves in the wrong direction.

The Limits of Regulation

For decades, regulation has focused on managing agricultural waste, rather than addressing how it is produced.

In the late 1990s, a government assessment found that roughly 40 percent of assessed U.S. waterways were not fishable or swimmable, with agriculture identified as the leading source of pollution in both lakes and rivers. A subsequent joint USDA–EPA strategy report found that voluntary programs were insufficient and called for updated regulations for animal feeding operations. The report estimated that Clean Water Act (CWA) permit coverage could expand from 2,000 operations to as many as 20,000—nearly ten times the number of operations identified for federal oversight.

EPA’s 2008 CAFO rule followed, requiring permits for large operations that discharge or propose to discharge pollutants. The rule drew criticism from both sides. Environmental groups argued the rule did not go far enough, while industry groups opposed permits triggered by proposed discharges are too broad. These provisions continue to shape the federal framework, although later court rulings narrowed key elements.

These rules are written into law, but weak in practice. Over the past decade, Natural Resources Defense Council research shows that EPA lacks basic information on most operations, including their location, size, waste output, and handling practices. This gap is nothing new. The system regulates discharge, not production, and was never structured to track waste once it leaves the facility. This is the loophole: responsibility ends once waste leaves.

Under this framework, a CAFO can satisfy its permit by moving excess manure off-site, regardless of how that waste is ultimately handled. Compliance is measured by transfer, not outcomes.

Once manure leaves a facility, there is no mechanism to track what happens next. The paper trail thins to records of transfers and recipients, but regulatory responsibility ends at shipment. No federal system tracks where the manure goes or how it is applied. An Environmental Integrity Project analysis found widespread gaps in federal CAFO data, and in some regions, facilities ship up to 85 percent of their waste off-site, beyond the reach of federal oversight. This makes oversight difficult to carry out in practice.

This is not a gap EPA has missed, but one its framework does not address. EPA has documented agriculture as a leading source of water pollution and called for expanded permit coverage, while continuing to operate within the same framework. The issue is structural: the CWA regulates discharges, not production. Operations can confine animals at any density and generate any volume of waste while remaining outside federal oversight, so long as they do not discharge. Regulators have acknowledged limits in manure tracking and enforcement authority, yet those limits persist without reform. EPA can respond to pollution but cannot assess whether production levels exceed what permits can lawfully manage.

The public record can test these claims. Coire Media filed three FOIA requests with EPA seeking records on whether CAFO compliance depends on off-site manure disposal, whether manure is tracked after it leaves the facility, and whether the agency acknowledges its limits in tracking and enforcement. The requests focused on Duplin County, given its high concentration of CAFOs. If these systems existed, records would be available. Yet EPA reported no responsive records to any of the requests. Likewise, the North Carolina Department of Environmental Quality did not respond to a parallel request, despite confirmed receipt in February 2026. In a county producing this volume of waste, the absence of records is not a gap. It reflects the system itself.

What This Means

Factory farms continue to generate pollution without meaningful accountability. If production at current densities creates waste that cannot be lawfully managed, those levels are legally untenable. The issue is not how to manage the waste, but whether operating at this scale is lawful.

That legal question is inseparable from how responsibility is assigned. Integrator corporations design the system, set stocking densities, and dictate how animals are raised. Yet the legal and financial burden of managing the resulting waste falls on contract growers who do not set those decisions. Responsibility should follow control.

The solution begins with limiting the number of animals that facilities are allowed to confine in a single location. If operations produce more manure than can be lawfully applied nearby and rely on exporting it off-site, the issue is stocking density at the source. Intensive confinement drives pollution and can no longer be ignored or tolerated.

Without a system to track whether waste remains within legal limits, production continues unchanged despite well-documented harms to communities, the environment, and animals.

Moved or spread, the harm remains.
