Cow brains. Sheep guts. Chicken heads. Road kill. Rancid grain. These are a few of the so-called nutritionally balanced ingredients found in the commercial pet food served to companion animals every day.
More than 95 percent of US companion animals derive their nutritional needs from a single source: processed pet food. When people think of pet food, many envision whole chickens, choice cuts of beef, fresh grains, and all the nutrition that a dog or cat may ever need -- images that pet food manufacturers promote in their advertisements. What these companies do not reveal is that instead of whole chickens they have substituted chicken heads, feet, and intestines. Those choice cuts of beef are really cow brains, tongues, esophagi, fetal tissue dangerously high in hormones, and possibly diseased and even cancerous meat. Those whole grains have had the starch removed for corn starch powder and the oil extracted for corn oil, or they are hulls and other remnants from the milling process. Grains used that are truly whole have usually been deemed unfit for human consumption because of mold, contaminants, poor quality, or poor handling practices. Pet food is one of the worlds most synthetic edible products, containing virtually no whole ingredients.
Pet food manufacturers have become masters at inducing companion animals to eat things cat and dogs would normally spurn. Pet food scientists have learned that it's possible to take a mixture of inedible scraps, fortify it with artificial vitamins and minerals, preserve it so that it can sit on the shelf for more than a year, add dyes to make it attractive, and then extrude it into whimsical shapes that appeal to the human consumer. For this, pet food companies can expect to earn $9 billion in sales in 1996.
It is not happenstance that four of the top five major pet food companies in the United States are subsidiaries of major multinational food production companies: Colgate Palmolive (which produces Hills Science Diet), Heinz, Nestle, and Mars )see The Corporate Connection). From a business standpoint, multi-national food companies owning pet food manufacturers is an ideal relationship. The multinationals have captive market in which to dump their waste products, and the pet food manufacturers have a direct source of bulk materials. Both make a profit from selling scraps that originate from places far worse than the dinner table. In his 1986 book Pet Allergies veterinarian Al Plechner sums up what goes into companion animals food: Condemned parts and animals rejected for human consumption are routinely rerouted for commercial pet foods. A similar fate applies to so-called 4-D animals. These are food animals picked up dead, or that are dying, diseased, or disabled, and do not meet human-food qualifications. They are processed straightaway for companion animal consumption. Little goes to waste. Says Plechner, Food processing refuse of all sorts winds up in your animals dinner bowls. Moldy grains. Rancid foods. Meat meal. The latter is ground-up slaughterhouse discards often containing disease-ridden tissue and high levels of hormones and pesticides, the very things that may have contributed to the death of the steer or hog. A decade later, his words still apply. When cattle, swine, chickens, lambs, or other animals meet their ends at a slaughterhouse, the choice cuts -- lean muscle tissue and organs prized by humans -- are trimmed away from the carcass for human consumption. Whatever remains of the carcass (bones, blood, pus, intestines, ligaments, subcutaneous fat, hooves, horns, beaks, and any other parts not normally consumed by humans) is, according to the pet food industry, perfectly fit as a protein source for cat and dog food.
The Pet Food Institute, the trade association of pet food manufacturers, acknowledges in its 1994 Fact Sheet the importance of using byproducts in pet foods as additional income for processors and farmers. The purchase and use of these ingredients by the pet food industry not only provides nutritional foods for pets at reasonable costs, but provides an important source of income to American farmers and processors of meat, poultry, and seafood products for human consumption. Many of these remnants are indigestible and provide a questionable source of nutrition. The amount of nutrition provided by meat byproducts, meals, and digests varies from vat to vat of this animal protein soup. A vat filled with chicken feet, beaks, and viscera is going to make available a lower amount of protein than a vat of breast meat. James Morris and Quinton Rogers, professors with Department of Molecular Biosciences at the University of California at Davis Veterinary School of Medicine, assert that there is virtually no information on the bio-availability of nutrients for companion animals in many of the common dietary ingredients used in pet foods. These ingredients are generally byproducts of the meat, poultry and fishing industries, with the potential for wide variation in nutrient composition. Claims of nutritional adequacy of pet foods based on the current AAFCO nutrient allowances (profiles) do not give assurances of nutritional adequacy and will not until ingredients are analyzed and bioavailability values are incorporated. Meat byproducts, the catch-all term of the pet food industry, is a misnomer because these byproducts contain little if any meat. Byproducts contain little if any meat. Byproduct are animal parts leftover after the meat has been stripped from the bone. Chicken byproducts include heads, feet, entrails, lungs, spleens, kidneys, brains, livers, stomachs, noses, blood, and intestines free of their contents. What the pet food manufactures fail to mention is that most byproducts, digests and meals are also filled with other substances, such as cancerous tissue cut from the carcass, plastic foam packaging containing spoiled meat from supermarkets, ear tags, spoiled slaughterhouse meat, road kill, and pieces of downer animals.
Many pet foods advertised as preservative-free do not contain preservatives. Almost all rendered meats have synthetic preservatives added as stabilizer, but manufacturers aren't required to list preservatives they themselves haven't added. Premixed vitamin additives can also contain preservatives. In the 1003 Journal of the American Veterinary Medical Association, veterinarian Philip Roudebush reported finding low concentrations of synthetic antioxidant preservatives in all analyzed samples of products labeled as chemical free or all-natural. Other types of additives depend on whether the pet food is semi-moist, dry or canned. Because semi-moist food contains 25-50 percent water, antimicrobial preservatives must be used. Propylene glycol was frequently used in cat food until it was pulled in 1992 for causing a variety of health problems. Processing greatly alters the nutritional value of the food ingredients. Veterinarian R. L. Wysong states in Rationale for Animal Nutrition: Processing is the wild card in nutritional value that is, by and large, simply ignored. Heating, freezing, dehydrating, canning, extruding, pelleting, baking and so forth, are so commonplace that they are simply thought of as synonymous with food itself. Because the ingredients that pet food companies use are not wholesome, and harsh manufacturing practices destroy what little nutritional value the food may have had in the first place, the final product must be fortified with vitamins and minerals.
It is sad to think that the food provided by animal care givers to their four-legged friends could be hazardous to the animals'; health and longevity. Care givers should assume responsibility for providing as healthful a diet as possible for the animals in the care. Consumers should be informed: speak with a holistic practitioner or herbalist, or consult your veterinarian (but be aware that a veterinarian's knowledge of nutrition may be limited to the two weeks of nutrition he or she had veterinary school 20 years ago). Although the ideal solution would be for companion animals to be fed only wholesome homemade and/or vegetarian diets, this is not an optician for everyone -- the cost and time commitment is sometimes prohibitive. By taking more moderate steps, however, care givers can still greatly improve a companion animals' diet and quality of life.
