What's Really in Pet Food

Plump
whole chickens, choice cuts of beef, fresh grains, and all the wholesome
nutrition your dog or cat will ever need.
These
are the images pet food manufacturers promulgate through the media and
advertising. This is what the $11 billion per year U.S.
pet food industry wants consumers to believe they are buying when they purchase
their products.
This
report explores the differences between what consumers think they are buying
and what they are actually getting. It focuses in very general terms on the
most visible name brands -- the pet food labels that are mass distributed to
supermarkets and discount stores -- but there are many highly respected brands
that may be guilty of the same offenses.
What
most consumers don't know is that the pet food industry is an extension of the
human food and agriculture industries. Pet food provides a market for
slaughterhouse offal, grains considered "unfit for human
consumption," and similar waste products to be turned into profit. This
waste includes intestines, udders, esophagi, and possibly diseased and
cancerous animal parts.
Three
of the five major pet food companies in the United States are subsidiaries of
major multinational companies: NestlŽ (Alpo, Fancy Feast, Friskies, Mighty Dog,
and Ralston Purina products such as Dog Chow, ProPlan, and Purina One), Heinz
(9 Lives, Amore, Gravy Train, Kibbles-n-Bits, Nature's Recipe),
Colgate-Palmolive (Hill's Science Diet Pet Food). Other leading
companies include Procter & Gamble (Eukanuba and Iams), Mars (Kal Kan, Mealtime,
Pedigree, Sheba, Waltham's), and Nutro. From a business standpoint,
multinational companies owning pet food manufacturing companies is an ideal
relationship. The multinationals
have increased bulk-purchasing power; those that make human food products have
a captive
market in which to capitalize on their waste products, and pet food
divisions have a more reliable capital base and, in many cases, a convenient
source of ingredients.
There
are hundreds of different pet foods available in this country. And while many
of the foods on the market are similar, not all of the pet food manufacturing
companies use poor quality or potentially dangerous ingredients.
Ingredients
Although
the purchase price of pet food does not always determine whether a pet food is
good or bad, the price is often a good indicator of quality. It would be
impossible for a company that sells a generic brand of dog food at $9.95 for a
40-lb. bag to use quality protein and grain in its food. The cost of purchasing
quality ingredients would be much higher than the selling price.
The
protein used in pet food comes from a variety of sources. When cattle, swine, chickens,
lambs, or other animals are slaughtered, the choice cuts such as lean muscle
tissue are trimmed away from the carcass for human consumption. However, about
50% of every food-producing animal does not get used in human foods. Whatever
remains of the carcass -- bones, blood, intestines, lungs, ligaments, and
almost all
the other parts not generally consumed by humans -- is used in pet food,
animal feed, and other products. These "other parts" are known as
"by-products," "meat-and-bone-meal," or similar names on
pet food labels.
The
Pet Food Institute -- the trade association of pet food manufacturers --
acknowledges the use of by-products in pet foods as additional income for
processors and farmers: "The growth of the pet food industry not only
provided pet owners with better foods for their pets, but also created
profitable
additional markets for American farm products and for the byproducts of
the meat packing, poultry, and other food industries which prepare
food for human consumption." 1
Many
of these remnants provide a questionable source of nourishment for our animals.
The nutritional
quality of meat and poultry by-products, meals, and digests can vary
from batch to batch. James Morris and Quinton Rogers, two professors with
the Department of Molecular Biosciences, University of California at Davis
Veterinary School of Medicine, assert that, "There is virtually no
information on the bioavailability of nutrients for companion animals in many
of the common dietary ingredients used in pet foods. These ingredients are
generally by-products of the meat, poultry and fishing industries, with
the
potential for a wide variation in nutrient composition. Claims of
nutritional adequacy of pet foods based on the current Association of American
Feed Control Officials (AAFCO) nutrient allowances ('profiles') do not give
assurances of nutritional adequacy and will not until ingredients are analyzed
and
bioavailability values are incorporated." 2
Meat
and poultry meals, by-product meals, and meat-and-bone meal are common
ingredients in pet foods. The term "meal" means that these materials
are not used fresh, but have been rendered. What is rendering? Rendering, as
defined by Webster's
Dictionary, is "to process as
for industrial use: to render livestock carcasses and to extract
oil from fat, blubber, etc., by melting." Home-made chicken soup,
with its thick layer of fat that
forms over the top when the soup is cooled, is a sort of mini-rendering
process. Rendering separates fat-soluble from water-soluble and solid
materials, removes most of the water, and kills bacterial contaminants, but may
alter or destroy some of the natural enzymes and proteins found in the raw
ingredients. Meat and poultry by-products, while not rendered, vary widely in
composition and quality.
What
can the feeding of such products do to your companion animal? Some
veterinarians claim that feeding slaughterhouse wastes to animals increases
their risk of getting cancer and other degenerative diseases. The cooking
methods used by pet food manufacturers -- such as rendering, extruding (a
heat-and-pressure system used to "puff" dry foods into nuggets or
kibbles), and baking -- do not necessarily destroy the hormones used to fatten
livestock or increase milk production, or drugs such as antibiotics or the
barbiturates used to euthanize animals.
Animal and Poultry Fat
You
may have noticed a unique, pungent odor when you open a new bag of pet food --
what is the source of that delightful smell? It is most often rendered animal
fat, restaurant grease, or other oils too rancid or deemed inedible for humans.
Restaurant
grease has become a major component of feed grade animal fat over the last
fifteen years. This grease, often held in fifty-gallon drums, may be kept
outside for weeks, exposed to extreme temperatures with no regard for its
future use. "Fat blenders" or rendering companies then pick up this
used grease and mix the different types of fat together, stabilize them with
powerful antioxidants to retard further spoilage, and then sell the blended
products to pet food companies and other end users.
These
fats are sprayed directly onto extruded kibbles and pellets to make an
otherwise bland or distasteful product palatable. The fat also acts as a binding
agent to which manufacturers add other flavor enhancers such as digests.
Pet food scientists have discovered that animals love the taste of these
sprayed fats. Manufacturers are masters at getting a dog or a cat to eat
something she would normally turn up her nose at.
Wheat, Soy, Corn, Peanut Hulls, and Other
Vegetable Protein
The
amount of grain products used in pet food has risen over the last decade. Once
considered filler by the pet food industry, cereal and grain products now
replace a considerable proportion of the meat that was used in the first
commercial pet foods. The availability of nutrients in these products is
dependent upon the digestibility of the grain. The amount and type of
carbohydrate in pet food determines the amount of nutrient value the animal
actually gets. Dogs and cats can almost completely absorb carbohydrates from
some grains, such as white rice. Up to 20% of the nutritional value of other
grains can escape digestion.
The availability of nutrients for wheat, beans, and oats is poor. The
nutrients in potatoes and corn are far less available than those in rice. Some
ingredients, such as peanut hulls, are used for filler or fiber, and have no
significant nutritional value.
Two
of the top three ingredients in pet foods, particularly dry foods, are almost
always some form of grain products. Pedigree Performance Food for Dogs lists
Ground Corn, Chicken By-Product Meal, and Corn Gluten Meal as its top three
ingredients. 9 Lives Crunchy Meals for cats lists Ground Yellow Corn, Corn Gluten Meal,
and Poultry By-Product Meal as its first three ingredients. Since cats are true
carnivores -- they must eat meat to fulfill certain physiological needs -- one
may wonder why we are feeding a corn-based product to them. The answer is that
corn is a much cheaper "energy source" than meat.
In
1995, Nature's Recipe pulled thousands of tons of dog food off the shelf after
consumers complained that their dogs were vomiting and losing their appetite.
Nature's Recipe's loss amounted to $20 million. The problem was a fungus that
produced vomitoxin (an aflatoxin or "mycotoxin," a toxic substance
produced by mold) contaminating
the wheat. In 1999, another fungal toxin triggered the recall of dry dog food
made by
Doane Pet Care at one of its plants, including Ol' Roy (Wal-Mart's brand) and
53 other brands. This time, the toxin killed 25 dogs.
Although
it caused many dogs to vomit, stop eating, and have diarrhea, vomitoxin is a
milder toxin than most. The more dangerous mycotoxins can cause weight loss,
liver damage, lameness, and even death as in the Doane case. The Nature's
Recipe incident prompted the Food and Drug Administration (FDA) to intervene.
Dina Butcher, Agriculture Policy Advisor for North Dakota Governor Ed Schafer,
concluded that the discovery of vomitoxin in Nature's
Recipe wasn't much of a threat to the human population because "the grain
that would go into pet food is not a high quality grain." 3
Soy
is another common ingredient that is sometimes used as a protein and energy
source in pet food. Manufacturers also use it to add bulk so that when an
animal eats a product containing soy he will feel more sated. While soy has
been linked to gas in some dogs, other dogs do quite well with it. Vegetarian
dog foods use soy as a protein source.
Additives and Preservatives
Many
chemicals are added to commercial pet foods to improve the taste, stability,
characteristics, or appearance of the food. Additives provide no nutritional
value. Additives include emulsifiers to prevent water and fat from separating,
antioxidants to prevent fat from turning rancid, and artificial colors and
flavors to make the product more attractive to consumers and more palatable to
their companion animals.
Adding
chemicals to food originated thousands of years ago with spices, natural
preservatives, and ripening agents. In the last 40 years, however, the number
of food additives has greatly increased.
All
commercial pet foods must be preserved so they stay fresh and appealing to our
animal companions. Canning is a preserving process itself, so canned foods
contain less preservatives than dry foods. Some preservatives are added to
ingredients or raw materials by the suppliers, and others may be added by the manufacturer.
Because manufacturers need to ensure that dry foods have a long shelf life to
remain edible after shipping and prolonged storage, fats used in pet foods are
preserved with either synthetic or "natural" preservatives. Synthetic
preservatives include butylated
hydroxyanisole (BHA) and butylated hydroxytoluene
(BHT) , propyl gallate, propylene
glycol (also used as a less-toxic version of automotive antifreeze), and ethoxyquin . For these antioxidants, there is little information
documenting their toxicity, safety, interactions, or chronic use in pet foods
that may be eaten every day for the life of the animal.
Potentially
cancer-causing agents such as BHA, BHT, and ethoxyquin are permitted at
relatively low levels. The use of these chemicals in pet foods has not been
thoroughly studied, and long term build-up of these agents may ultimately be harmful. Due to questionable
data in the original study on its safety, ethoxyquin's manufacturer, Monsanto,
was required to perform a new, more rigorous study. This was completed in 1996.
Even though Monsanto found no significant toxicity associated with its own
product, in July 1997, the FDA's Center for Veterinary Medicine requested that
manufacturers voluntarily reduce the maximum level for ethoxyquin by half, to
75 parts per million. While some pet food critics and veterinarians believe
that ethoxyquin is a major cause of disease, skin problems, and infertility in
dogs, others claim it is the safest, strongest, most stable preservative
available for pet food. Ethoxyquin is approved for use in human food for
preserving spices, such as cayenne and chili powder, at a level of 100 ppm --
but it would be very difficult to consume as much chili powder every day as a
dog would eat dry food. Ethoxyquin has never been tested for safety in cats.
Some
manufacturers have responded to consumer concern, and are now using
"natural" preservatives such as Vitamin C (ascorbate), Vitamin E
(mixed tocopherols), and oils of rosemary, clove, or other spices, to preserve
the fats in their products. Other ingredients, however, may be individually
preserved. Most fish meal, and some prepared vitamin-mineral mixtures, contain
chemical preservatives. This means that your companion animal may be eating
food containing several types of preservatives. Federal law requires
preservatives to be disclosed on the label; however, pet food companies only
recently started to comply with this law.

Some authors have suggested that
dangerous interactions occur among some of the common synthetic preservatives. 4Natural
preservatives do not provide as long a shelf life as chemical preservatives,
but they are safe.
The Manufacturing Process
How Pet Food Is Made
Although
feeding trials are no longer required for a food to meet the requirements for
labeling a food "complete and balanced," most manufacturers perform palatability
studies when developing a new pet food. One set of animals is fed a new food
while a "control" group is fed a current formula. The total
volume
eaten is used as a gauge for the palatability of the food. The larger
and more reputable companies do use feeding trials, which are considered to be
a much more accurate assessment of the actual nutritional value of the food. They keep large colonies
of dogs and cats for this purpose, or use testing laboratories that have their
own animals.
Most
dry food is made with a machine called an expander or extruder. First, raw
materials are blended, sometimes by hand, other times by computer, in
accordance with a recipe developed by animal nutritionists. This mixture is fed
into an expander and steam or hot water is added. The mixture is subjected to
steam,
pressure, and high heat as it is extruded through dies that determine
the shape of the final product and puffed like popcorn. The food is allowed to
dry, and then is usually sprayed with fat, digests, or other compounds to make
it more palatable. Although the cooking process may kill bacteria in pet food,
the final
product can lose its sterility during the subsequent drying, fat
coating, and packaging process. A few
foods are baked at high temperatures rather than extruded. This produces
a dense, crunchy kibble that is palatable without the addition of sprayed on
palatability enhancers. Animals can be fed about 25% less of a baked food,
by volume (but not by weight), than an extruded food.
Ingredients
are similar for wet, dry, and semi-moist foods, although the ratios of protein,
fat, and fiber may change. A typical can of ordinary cat food reportedly
contains about 45-50% meat or poultry by-products. The main difference between
the types of food is the water content. It is impossible to directly compare labels from different
kinds of food without a mathematical conversion to "dry matter
basis." 5Wet or canned food begins with ground ingredients
mixed with additives. If chunks are required, a special extruder forms them.
Then the mixture is cooked and canned. The sealed cans are then put into
containers resembling pressure cookers and commercial sterilization takes place.
Some manufacturers cook the food right in the can.
There
are special labeling requirements for pet food, all of which are contained in
the annually revised Official Publication of AAFCO. 6The use of the
terms "all" or "100%" cannot be used "if the product
contains more than one ingredient, not including water sufficient for
processing, decharacterizing agents, or trace amounts of preservatives and
condiments." Products containing multiple ingredients are covered by AAFCO
Regulation PF3(b) and (c). The "95% rule" applies when the
ingredient(s) derived from animals, poultry, or fish constitutes at least 95%
or more of the total weight of the product (or 70% excluding water for
processing).
Because
all-meat diets are usually not nutritionally balanced, they fell out of favor
for many years. However, due to rising consumer interest in high quality meat
products, several companies are now promoting 95% and 100% canned meats as a
supplemental feeding option.
The
"dinner" product is defined by the 25% Rule, which applies when
"an ingredient or a combination of ingredients constitutes at least 25% of
the weight of the product" (excluding water sufficient for processing) as
long as the ingredient(s) shall constitute at least 10% of the total product
weight; and a
descriptor that implies other ingredients are included in the product
formula is used on the label. Such
descriptors include "recipe," "platter,"
"entree," and "formula." A combination of ingredients
included in the product name is permissible when each ingredient comprises at
least 3% of the product weight, excluding water for processing, and
the ingredient names appear in descending order by weight.
The
"with" rule allows an ingredient name to appear on the label, such as
"with real chicken," as long as each such ingredient constitutes at
least 3% of the food by weight, excluding water for processing.
The
"flavor" rule allows a food to be designated as a certain flavor as
long as the ingredient(s) are sufficient to "impart a distinctive
characteristic" to the food. Thus, a "beef flavor" food may contain
a small quantity of digest or other extract of tissues from cattle, without
containing any actual beef meat at all.
What Happened to the Nutrients?
Dr.
Randy L. Wysong is a veterinarian and produces his own line of pet foods. A
long-time critic of pet food industry practices, he said, "Processing is
the wild card in nutritional value that is, by and large, simply ignored.
Heating, cooking, rendering, freezing, dehydrating, canning, extruding,
pelleting, baking, and so forth, are so commonplace that they are simply
thought of as synonymous with food itself." 7Processing meat and by-products
used in pet food can greatly diminish their nutritional value, but cooking
increases the digestibility of cereal grains.
To
make pet food nutritious, pet food manufacturers must "fortify" it
with vitamins and minerals. Why?
Because the ingredients they are using are not wholesome, their quality
may be extremely variable, and the harsh manufacturing practices destroy many
of the nutrients the food had to begin with.
Contaminants
Commercially
manufactured or rendered meat meals and by-product meals are frequently highly
contaminated with bacteria because their source is not always slaughtered
animals. Animals that have died because of disease, injury, or natural causes
are a source of meat for meat meal. The dead animal might not be rendered until
days after its death. Therefore the carcass is often contaminated with bacteria
such as Salmonella and Escherichia coli. Dangerous E. Coli bacteria are estimated
to contaminate more than 50% of meat meals. While the cooking process may kill
bacteria, it does not eliminate the endotoxins some bacteria produce during their growth
and are released when they die. These toxins can cause sickness and disease.
Pet food manufacturers do not test their products for endotoxins.
Mycotoxins
-- These toxins comes from mold or fungi, such as vomitoxin in the Nature's
Recipe case, andaflatoxin in Doane's food. Poor farming practices and improper
drying and storage of crops can cause mold growth. Ingredients that are most
likely to be contaminated with mycotoxins are grains such as wheat and corn,
cottonseed meal, peanut meal, and fish meal.
Labeling
The
National Research Council (NRC) of the Academy of Sciences set the nutritional
standards for pet
food that were used by the pet food industry until the late 1980s. The
NRC standards, which still exist
and are being revised as of 2001, were based on purified diets, and
required feeding trials for pet foods claimed to be "complete"
and "balanced." The pet food industry found the feeding trials too
restrictive and expensive, so AAFCO designed an alternate procedure for claiming
the nutritional adequacy of pet food, by testing the food for compliance with
"Nutrient Profiles." AAFCO also created "expert committees"
for canine
and feline nutrition, which developed separate canine and feline standards.
While feeding trials can still be done, a standard chemical analysis may be
also be used to determine if a food meets the profiles.
Chemical
analysis, however, does not address the palatability, digestibility, or
biological availability of nutrients in pet food. Thus it is unreliable for
determining whether a food will provide an animal with sufficient nutrients.
To
compensate for the limitations of chemical analysis, AAFCO added a "safety
factor," which was to exceed the minimum amount of nutrients required to
meet the complete and balanced requirements.
The
digestibility and availability of nutrients is not listed on pet food labels.
The 100% Myth -- Problems Caused by Inadequate
Nutrition
The
idea of one pet food providing all the nutrition a companion animal will ever
need for its entire life is a myth.
Cereal
grains are the primary ingredients in most commercial pet foods. Many people
select one pet food and feed it to their dogs and cats for a prolonged period
of time. Therefore, companion dogs and cats eat a primarily carbohydrate diet
with little variety. Today, the diets of cats and dogs are a far cry from the
primarily protein diets with a lot of variety that their ancestors ate. The
problems associated with a commercial diet are seen every day at veterinary
establishments. Chronic digestive problems, such as chronic vomiting, diarrhea, and
inflammatory bowel disease are among the most frequent illnesses treated. These
are often the result of an allergy or intolerance to pet food ingredients. The
market for "limited antigen" or "novel protein" diets is
now a multi-million dollar business. These diets were formulated to address the
increasing intolerance to commercial foods that animals have developed. The
newest twist is the truly "hypoallergenic" food that has had all its
proteins artificially chopped into pieces smaller than can be recognized and
reacted to by the immune system.
Dry
commercial pet food is often contaminated with bacteria, which may or may not
cause problems. Improper food storage and some feeding practices may result in
the multiplication of this bacteria. For example, adding water or milk to
moisten pet food and then leaving it at room temperature causes bacteria to multiply. 8Yet this
practice is suggested on the back of packages of some kitten and puppy foods.
Pet
food formulas and the practice of feeding that manufacturers recommend have
increased other digestive problems. Feeding only one meal per day can cause the
irritation of the esophagus by stomach acid. Feeding two smaller meals is
better.
Feeding
recommendations or instructions on the packaging are sometimes inflated so that
the consumer will end up purchasing more food. However, Procter & Gamble
allegedly took the opposite tack with its Iams and Eukanuba lines, reducing the
feeding amounts in order to claim that its foods were less expensive to feed.
Independent studies commissioned by a competing manufacturer suggested that
these reduced levels were inadequate to maintain health.
Procter & Gamble has since sued and been countersued by that competing manufacturer,
and a consumer complaint has also been filed seeking class-action status for
harm caused to dogs by the revised feeding instructions.
Urinary
tract disease is directly related to diet in both cats and dogs. Plugs,
crystals, and stones in cat bladders are often triggered or aggravated by
commercial pet food formulas. One type of stone found in cats is less common
now, but another more dangerous type has become more common. Manipulation
of
manufactured cat food formulas to alter the acidity of urine and the
amount of some minerals has directlyaffected these diseases. Dogs also form
stones as a result of their diet.
History
has shown that commercial pet food products can cause disease. An often-fatal
heart disease in cats and some dogs is now known to be caused by a deficiency
of the amino acid taurine. Blindness is another symptom of taurine deficiency.
This deficiency was due to inadequate amounts of taurine in cat food formulas,
which itself occurred because of decreased amounts of animal proteins and
increased reliance on carbohydrates. Cat foods are now supplemented with
taurine. New research suggests that supplementing taurine may also be helpful
for dogs, but as yet few manufacturers are adding extra taurine to dog food.
Inadequate potassium in certain feline diets also caused kidney failure in
young cats; potassium is now added in greater amounts to all cat foods.
Rapid
growth in large breed puppies has been shown to contribute to bone and joint
disease. Excess calories and calcium in some manufactured puppy foods promoted
rapid growth. There are now special puppy foods for large breed dogs. But this
recent change will not help the countless dogs who lived and died with hip and
elbow disease.
There
is also evidence that hyperthyroidism in cats may be related to excess iodine
in commercial pet food diets. 9This is a new disease that first surfaced in the
1970s, when canned food products appeared on the market. The exact cause and
effect are not yet known. This is a serious and sometimes terminal disease, and
treatment is expensive.
Many
nutritional problems appeared with the popularity of cereal-based commercial
pet foods. Some have occurred because the diet was incomplete. Although several
ingredients are now supplemented, we do not know what ingredients future
researchers may discover that should have been supplemented in pet foods all
along. Other problems may result from reactions to additives. Others are a
result of contamination with bacteria, mold, drugs, or other toxins. In some
diseases the role of commercial pet food is understood; in others, it is not.
The bottom line is that diets composed primarily of low quality cereals and
rendered meat meals are not as nutritious or safe as you should expect for your
cat or dog.
