Industrial Food Animal Production

The average American consumes more meat, milk, and eggs than nearly any other citizen of the world.1 Where do most of these animal products come from, and why does it matter?
For most of agriculture’s history, farm animals were raised on diversified farms, where they generally had access to the outdoors and ample space to move about. Although conditions like these still exist, the industrialization of agriculture radically transformed how most animals are raised for food.
At the end of 2012, the U.S. population of poultry, swine, cattle, and other food-producing animals numbered over 2 billion—outnumbering U.S. citizens by seven to one. Over the course of a typical year, over 9 billion are slaughtered.2 The vast majority of these animals are raised in a system called industrial food animal production, or IFAP (pronounced “eye-fap”).
In IFAP, poultry and swine are confined in densely stocked indoor facilities. A single IFAP facility, for example, typically houses over 5,000 hogs, or over 100,000 laying hens.2 Beef and dairy cattle spend at least part of their lives in similarly large-scale indoor or outdoor feeding operations.3,4 IFAP facilities are designed to maximize the amount of meat, milk, or eggs from a particular breed of animal in the shortest amount of time and at the lowest cost. They are also heavily dependent on specially formulated animal feeds, pharmaceutical drugs, fossil fuels, and other inputs to the production system.
IFAP produces an enormous amount of food with minimal human labor, and has been credited with lowering the price of meat, eggs, and milk.5 However, IFAP incurs heavy costs to public health and ecosystems that are not reflected in the sales price of these products.

Large animal confinement factories… might drown in their own waste if they don’t haul it out whenever they can.
– Gene Logsdon, farmer8
Confining thousands or millions of animals in a small amount of space poses a challenge: what to do with the enormous amounts of feces and urine they generate? Poultry, swine, and cattle raised in U.S. operations produce an estimated 335 million tons of waste annually (not counting water weight)9—over 40 times the amount leaving sewage treatment plants.10 A single IFAP facility may produce as much waste as a small city,11 concentrated over a small area of land. To dispose of IFAP waste, producers typically spread or spray the manure onto nearby agricultural land.
When applied to crop fields, animal waste provides nutrients and organic matter that help crops grow, transforming waste into food. For this reason, farmers don’t typically think of it as “waste” and instead call it “manure.” IFAP facilities generate such a large quantity of waste in one place, however, that it is often much more than nearby crops can use—becoming a pollution problem rather than a source of fertility. When waste is over-applied, the excess may seep down into groundwater or be carried into nearby waterways as runoff (the flow of water,such as from rain or irrigation, over land). IFAP waste may also leak out of storage pits, or worse, overflow or rupture during heavy storms.12,13
Pollution from IFAP facilities is a public health and ecological problem because it may contain bacteria, viruses, parasites, veterinary drugs, hormones, heavy metals, excess nutrients, and other potentially harmful contaminants. People may be exposed to these hazards by drinking contaminated well water, for example, or by swimming and fishing in contaminated waters.10,14–16

In medicine, antibiotic drugs are used to kill or inhibit pathogens (disease-causing organisms), such as Staphylococcus aureus—bacteria that can cause skin, blood, and urinary tract infections. If a patient does not complete her or his full dose of antibiotics, however, they may succeed only in killing the most susceptible bacteria. Sir Alexander Fleming, who discovered the lifesaving antibiotic drug penicillin, warned in 1945 that “the ignorant man may easily underdose himself and by exposing his microbes to nonlethal quantities of the drug, make them resistant.” In a case of survival of the fittest, bacteria capable of surviving in the presence of the antibiotic grow and multiply. Eliminating the infection would then require treatment with a different antibiotic drug, or potentially several different drugs—and there are only so many different drugs available. For this reason, antibiotic-resistant infections are more difficult and expensive to treat,20 and potentially fatal.
Experiments in the 1940s and 1950s found that feeding low doses of antibiotics to animals caused them to gain weight faster and on less feed. These findings prompted the introduction of antibiotics to the diets of healthy poultry, swine, and cattle.21 By 2009, 80 percent of antibiotic drugs sold in the U.S. were used not for human medicine but for food animal production.22
The nonmedical use of antibiotics in food animal production creates an environment that favors antibiotic-resistant bacteria, eroding the effectiveness of lifesaving drugs. A growing body of evidence suggests pathogens (resistant or otherwise) spread from IFAP operations to nearby communities via workers,23,24 air,25–27 water,28 and flies,29 and to consumers via contaminated meat.30 These pathways add to the growing dangers of antibiotic-resistant infections.
WORKER HEALTH, WORKER JUSTICE
Who is responsible for the health and ecological problems of IFAP? Blame is sometimes targeted at the people who raise the animals. In many cases, however, they are as much a victim of an industrial system as they are a part of the problem.
In industrial swine and poultry production, for example, farmers (or “growers”) are often pressured into signing contracts with vertically integrated corporations that dictate how the animals must be raised.32 Signing a contract with an “integrator” often means taking out loans to build the required facilities. Debt can further pressure growers to accept the terms mandated by the integrator when it comes time to renew the contract. As one poultry grower said, “When you have that kind of debt load over you … you’re going to choose to sign the contract. You feel that there’s no other option when you owe … a million dollars.”32
People who raise animals in IFAP operations also face numerous health risks. Crowded conditions in IFAP operations present frequent opportunities for the transmission of disease-causing organisms between animals, and from animals to workers. IFAP workers may be responsible for handling animals, animal waste, and carcasses—all of which may harbor bacteria, viruses, and other pathogens, including antibiotic-resistant strains. Once infected, workers may spread these pathogens into their homes and communities.33
IFAP workers may also be exposed to a range of airborne hazards, including harmful gases emitted from animal waste, particles of dried feces and urine, animal dander, fungal spores, and bacterial toxins. These hazards contribute to a heavy health burden: at least one in four workers in indoor IFAP operations is estimated to have a respiratory illness such as asthma.34,35

Living near IFAP often means coping with flies, odors, polluted air, contaminated water, and an environment populated by disease-causing pathogens.
Studies suggest bacterial pathogens, harmful gases, and other environmental contaminants may spread from IFAP facilities to surrounding communities, increasing residents’ disease risks. Contaminants may be brought into communities by workers,23,24 blown out of ventilation systems,25–27 introduced into drinking and recreational waters,10,14–16,28 and spread by flies, birds, and other animals.29,36 People living closer to IFAP operations (or where IFAP waste is applied) often have higher rates of illness, including respiratory problems37–42 and infections with antibiotic-resistant pathogens.43
Overwhelming odors from IFAP facilities can be a nuisance for nearby residents—interfering with daily activities, social gatherings, and overall quality of life. One North Carolina resident living near an industrial hog facility testified, “I think about the time everybody sat down to eat supper, we had all the windows closed, but you couldn’t eat because the odor was just that strong … It’s just like you could eat [your food], but as soon as you got up or went outside … you threw it back up.”44 More than just an unpleasant smell, odors from IFAP facilities have been associated with physical and mental health problems, including high blood pressure, depression, anxiety, and difficulty sleeping.45–47.
IFAP facilities and the problems they bring are often unwanted in communities. Proposals for the construction of new facilities are frequently met with strong opposition from local residents. IFAP facilities are disproportionately located in low-income communities and communities of color, where residents may have less political influence to oppose them—a form of environmental injustice.48

All the arguments to prove man’s superiority cannot shatter this hard fact: In suffering, the animals are our equals.
– Peter Singer, ethicist
To accommodate the industrial model, animals and their environments are engineered to maximize productivity. Raising animals indoors eliminates weather from the equation, giving producers greater control over temperature, lighting, and other factors that influence productivity.5 Specialized confinement facilities maximize the number of animals per area, and allow for automated feeding, watering, ventilation, and waste removal.49
As a result, most animals in IFAP rarely if ever see the outdoors, let alone feel sunshine, experience day or night, or walk on grass. They are unable to perform many of their natural behaviors; pigs raised on concrete are unable to root in the earth with their powerful nose discs, chickens are unable to dust bathe, cattle are fed unnatural diets of grain that cause painful liver abscesses. In most egg production facilities, hens are confined to “battery cages” so small they are unable to spread their wings. Female pigs (sows) used for breeding are confined to “gestation crates” in which they are unable to turn around or groom themselves.5,49,50
The stress and crowding of confinement can cause animals to become aggressive toward one another. To prevent pecking among laying hens, beaks are removed with a hot blade. Pigs’ tails are amputated to prevent them from being bitten. Bodily alterations to animals are usually performed without anesthesia or any other form of pain relief, partly because it is viewed as too costly, even though it is widely accepted that such alterations are painful.5,49,51,52 Bodily alternations are not unique to IFAP; practices such as castration and dehorning are common on pasture-raised farms.
These physical and psychological harms are among many others not described here.
CHANGING DIETS, POLICIES, AND FARMING PRACTICES

How can the harms of industrial food animal production (IFAP) be remedied? Changing diets, government policies, and the way animals are raised could all make a difference.
Each of our food purchases is a “vote with our fork” that sends a market signal affecting what, where, and how food is produced. In the words of farmer and author Wendell Berry, “How we eat determines, to a considerable extent, how the world is used.”53
Compared to typical high-meat diets, eating a diet of mostly plants requires less agricultural land (see image),54–57 and produces less nitrogen pollution54,57 and greenhouse gas emissions.54,57–62 Reducing meat and dairy consumption, particularly among high meat-consuming countries like the U.S., is an urgent and necessary step toward achieving a sustainable future.63
IFAP is enabled by weak environmental regulations and economic incentives. Strengthening restrictions on antibiotic use, improving the enforcement of air- and water-quality standards, and raising animal welfare standards are just a few of the policy changes that could improve the lives of workers, communities, and animals.5
Changing farming practices
Ecological approaches to livestock production typically involve raising animals outdoors (weather permitting), at lower densities, without growth-promoting drugs, and on diverse farms that cultivate a variety of crop or animal species. Well-managed pasture-based farms avoid many of the public health problems of IFAP, offer farmers greater autonomy, and allow animals freedom to express their natural behaviors. Pasture-based production is not a perfect solution, however, however, in part because it requires much more land (see image)64,65 and may produce more greenhouse gas emissions than industrial production.Food animal production64–67
