Industrial Agriculture
Many of the ingredients used in food animal feed these days are not the kind
of food the animals are designed by nature to eat, including same species
meat; diseased animals; feathers, hair, skin, hooves, and blood; manure and
other animal waste; plastics; drugs and chemicals; and unhealthy amounts of
grains.

29968153 When many Americans think of farm animals, they picture cattle
munching grass on rolling pastures, chickens pecking on the ground outside
of picturesque red barns, and pigs gobbling down food at the trough.
Over the last 50 years, the way food animals are raised and fed has changed
dramatically—to the detriment of both animals and humans. Many people are
surprised to find that most of the food animals in the United States are no
longer raised on farms at all. Instead they come from crowded animal
factories, also known as large confined animal feeding operations (CAFOs).
Just like other factories, animal factories are constantly searching for
ways to shave their costs. To save money, they've redefined what constitutes
animal feed, with little consideration of what is best for the animals or
for human health. As a result, many of the ingredients used in feed these
days are not the kind of food the animals are designed by nature to eat.
Just take a look at what's being fed to the animals you eat.
Same Species Meat
Diseased Animals
Feathers, Hair, Skin, Hooves, and Blood
Manure and Other Animal Waste
Plastics
Drugs and Chemicals
Unhealthy Amounts of Grains
Are these ingredients legal? Unfortunately, yes. Nevertheless, some raise
human health concerns. Others just indicate the low standards for animal
feeds. But all are symptoms of a system that has lost sight of the
appropriate way to raise food animals.
Same Species Meat, Diseased Animals, and Feathers, Hair, Skin, and Blood
The advent of "mad cow" disease (also known as bovine spongiform
encephalopathy or BSE) raised international concern about the safety of
feeding rendered[1] cattle to cattle. Since the discovery of mad cow disease
in the United States, the federal government has taken some action to
restrict the parts of cattle that can be fed back to cattle.
However, most animals are still allowed to eat meat from their own species.
Pig carcasses can be rendered and fed back to pigs, chicken carcasses can be
rendered and fed back to chickens, and turkey carcasses can be rendered and
fed back to turkeys. Even cattle can still be fed cow blood and some other
cow parts.
Under current law, pigs, chickens, and turkeys that have been fed rendered
cattle can be rendered and fed back to cattle—a loophole that may allow mad
cow agents to infect healthy cattle.
Animal feed legally can contain rendered road kill, dead horses, and
euthanized cats and dogs.
Rendered feathers, hair, skin, hooves, blood, and intestines can also be
found in feed, often under catch-all categories like "animal protein
products."
Manure and Other Animal Waste
Feed for any food animal can contain cattle manure, swine waste, and poultry
litter. This waste may contain drugs such as antibiotics and hormones that
have passed unchanged through the animals' bodies.
The poultry litter that is fed to cattle contains rendered cattle parts in
the form of digested poultry feed and spilled poultry feed. This is another
loophole that may allow mad cow agents to infect healthy cattle.
Animal waste used for feed is also allowed to contain dirt, rocks, sand,
wood, and other such contaminants.
Plastics
Many animals need roughage to move food through their digestive systems. But
instead of using plant-based roughage, animal factories often turn to
pellets made from plastics to compensate for the lack of natural fiber in
the factory feed.
Drugs and Chemicals
Animals raised in humane conditions with appropriate space and food rarely
require medical treatment. But animals at animal factories often receive
antibiotics to promote faster growth and to compensate for crowded,
stressful, and unsanitary living conditions. An estimated 13.5 million
pounds of antibiotics—the same classes of antibiotics used in human
medicine—are routinely added to animal feed or water. This routine,
nontherapeutic use of antibiotics speeds the development of
antibiotic-resistant bacteria, which can infect humans as well as animals.
Antibiotic resistance is a pressing public health problem that costs the
U.S. economy billions of dollars each year.
Some of the antimicrobials used to control parasites and promote growth in
poultry contain arsenic, a known human carcinogen. Arsenic can be found in
meat or can contaminate human water supplies through runoff from factory
farms.
Unhealthy Amounts of Grains
One last surprise. While grain may sound like a healthful food, the
excessive quantities fed to some animals are not. This is especially true
for cattle, which are natural grass eaters. Their digestive systems are not
designed to handle the large amounts of corn they receive at feedlots. As a
result of this corn-rich diet, feedlot cattle can suffer significant health
problems, including excessively acidic digestive systems and liver
abscesses. Grain-induced health problems, in turn, ramp up the need for
drugs.

Want to Change What Animals are Fed?
The rise in animal factories over the last 50 years has led to a system that
is out of control. Mad cow disease, increased liver abscesses, and the rise
of antibiotic-resistant bacteria are just some examples of the damage that
comes from unwise and often inhumane approaches to raising food animals.
As a consumer armed with information, you have the power to promote a modern
approach to raising animals that is both productive and healthful. You can
help to effect change by supporting systems and producers that feed animals
the food they were meant to eat.
You can:
Avoid factory farmed animal products altogether by choosing plant-based
foods.
Choose grass-fed and grass-finished beef and dairy products and
pasture-raised pork, poultry, and egg products.
Select certified organic meats, eggs, and dairy and those clearly labeled as
using only vegetarian animal feed.
Purchase meats, eggs, and dairy products from local farmers on the farm, at
farmers markets, or by buying a share from a local farmer as part of a
Community Supported Agriculture (CSA) program.

[1] Rendering is an industrial process in which animal carcasses, parts, and
other wastes are ground up, heated, and further processed to create a
variety of products, including animal feed ingredients. Meat and bone meal,
blood meal, and feather meal are some examples of rendered products.
