The Shocking Truth About Commercial Dog Food

Share

Warning!  The following story is shocking… but true.  It’s taken with permission from an article which appeared in the Earth Island Journal:

“The rendering plant floor is piled high with “raw product”… Thousands of dead dogs and cats; heads and hooves from cattle, sheep, pigs and horses; whole skunks; rats and raccoons… all waiting to be processed. In the ninety degree heat, the piles of dead animals seem to have a life of their own as millions of maggots swarm over the carcasses.

“Two bandanna-masked men begin operating Bobcat mini-dozers, loading the “raw” into a ten-foot deep stainless steel pit. They are undocumented workers from Mexico doing a dirty job. A giant auger at the bottom of the pit begins to turn. Popping bones and squeezing flesh are sounds from a nightmare you will never forget.

“Rendering is the process of cooking raw animal material to remove the moisture and fat. The rendering plant works like a giant kitchen. The cooker, or “chef”, blends the raw product in order to maintain a certain ratio between the carcasses of pets, livestock, poultry waste and supermarket rejects.

“Once the mass is cut into small pieces, it is transported to another auger for fine shredding. It is then cooked at 280 degrees for one hour. The continuous batch cooking process goes on non-stop, 24 hours a day, seven days a week as meat is melted away from bones in the hot “soup”. During this cooking process, the “soup” produces a fat of yellow grease or tallow that rises to the top and is skimmed off. The cooked meat and bone are sent to a hammer-mill press, which squeezes out the remaining moisture and pulverizes the product into a gritty powder. Shaker screens sift out excess hair and large bone chips. Once the batch is finished, all that is left is yellow grease, meat and bone meal.”

Welcome to the Dark Side of Recycling

So, what on earth could this unsavory concoction be legitimately used for?

Certainly not to make anything edible… right?

Unfortunately… as hard as it is to believe… the final “product” of this grisly process is sold as a source of protein and fat for making animal feeds.

That’s right… food ingredients to be fed to chickens, pigs, cattle… and you guessed it… dogs!

These revolting products are actually used to make dog food.

Every day, hundreds of rendering plants across America ship thousands of pounds of this recycled garbage to ranches, farms, feed lots… and pet food manufacturers.

Each batch of rendered product is labeled… according to its dominant animal source.  That’s why on a dog food label you’ll see so many ingredients that look like these…

  • Poultry by-product meal
  • Meat by-product meal
  • Fish meal
  • Animal fat

All are products of the rendering process.

Toxic Waste and Euthanized Pets

But this same complex system which converts waste into animal feed has also evolved into a recycling nightmare.  That’s because rendering plants are unavoidably processing toxic waste, too.

Here’s how…

The dead animals are frequently accompanied by a host of unwanted ingredients.  Pesticides enter the rendering process via tainted livestock.

Fish oil is commonly contaminated with mercury and other heavy metals.

Dead pets are frequently thrown into the grinder with their flea collars still attached.  Insecticide-laced patches found on the skin of slaughtered cattle are also carelessly added to the mix.

Antibiotics and other pharmaceuticals follow livestock directly into the soup.  And drugs given to euthanize pets have been regularly found in the rendered product.

Unwanted metal contaminants can be traced to a variety of sources including pet collars, ID tags, surgical pins, and needles.

Even plastics end up getting into the process.

Finding a Use for Spoiled Grocery Meats

Every day, out-of-date supermarket meats as well as spoiled fish and poultry arrive by the truckload… right in their original Styrofoam trays and shrink wrap.  There’s simply no time for the tedious task of unwrapping each individual package of the many thousands of rejected products.

Plastic cattle ID lags, pesticide patches and even the green waste disposal bags containing pets from veterinarians are tossed directly into the pit.

As you can see, literally all of it (plastic, paper, cardboard, and whatever) goes right into the rendering machine.

By now, you must be starting to figure it all out.  Much of what goes into dog food is simply what’s left over after the processing of human food.  It’s what’s commonly classified as “unfit for human consumption”.

Unfit for Humans… Legal for Dog Food

Here’s a short list of some of the unsavory raw materials I’ve already mentioned… plus a few others.  All of the following ingredients are appalling… yet each can be lawfully used to make dog food:

  • Slaughterhouse waste (organs, heads, hooves, beaks, feet)
  • Bread and cereal rejects (cobs, stalks, mill sweepings)
  • Contaminated grain middlings
  • Dying, diseased and disabled farm animals
  • Road kill (deer, skunks, and raccoons)
  • Distiller fermentation waste
  • Spoiled supermarket food
  • Dead zoo animals
  • Restaurant grease
  • Euthanized cats and dogs

The pet food industry can be… at least in part… a sinister waste disposal vehicle for the human food manufacturers… and a way to profit from its own garbage.  Many companies practice legal witchcraft by magically turning their trash… into cash.

My Strongest Recommendation

Learn to readily spot these “profit-first” dog food companies… and avoid buying their second-rate products.

Look for brands made by conscientious manufacturers who take great pride in producing top-tier products… products designed to significantly enhance… and extend your dog’s life.

Learn why you should be skeptical of dog food products that claim to be “premium”, “natural” or “gourmet”.

    Yeah, one of these days, Gordon, I’ll get her switched to raw or at least a high quality canned. For right now, though, I have a daughter, and two new baby boys, so it’s going to be a minute before we can afford any extras! By the way, you mention grass-fed meats, and let me tell you, they are not readily accessible. You can’t get them in a grocery store on anything like that. You really have to find local farms that raise grass-fed meats, and even then, you have to make sure they are truly grass-fed and not just “pastured”. Grass-fed is quite expensive, too. Have a look at this website… he sells grass-fed meats for people and pets, and has a bunch of interesting omega-3 essays…

    texasgrassfedbeef.com

  • Gordon

    My apologies, as there is a usually, regular 4th BARF (Biologically Appropriate Raw Foods) proponent and advocate (Not including the website’s author, as I’m specifying posters only) that posts here and that’s Jonathan, although he mostly feeds his Lab a rotation of the better quality kibble brands, but more so due to the economy of it, as do I, albeit an alternation of raw and so-called top drawer kibbles (I’m always cautious to give the latter my full faith), for the very same economical reasons. With added raw organic and antibiotic raw eggs once a week, and 100% air-dried beef liver, lamb crumbles, pig ears, roo tails etc, as a small daily treat, sometimes placed in a Buster Cube.

    I’ll also give them variety of hopefully drug free raw meaty bones, one each on a nightly basis, and organic yoghurt every second dinner mixed with so-called premium grain free kibble.

  • Gordon

    Having said the above, and as much as I’d like to find the time to formulate my own BARF meals for my dogs, as I said I would now do, thanks to Dr. B’s profanity, I realistically can not do this, time-wise. And because, I’m more limited in my choices down under re commercial type BARF dog foods, due to less competition (309 mill people in US as opposed to 21 mill in Australia), I am considering K9′s raw frozen (Not freeze-dried, as we have access to the actual raw frozen version down under), until my investigation into that product is complete. The other consideration is ZiwiPeak’s air-dried raw brand, which is not exactly cheap.

  • Gordon

    With regard to BARF diets of raw meats etc. These also can cause diseases including cancers for the very fact as Shawna, stated, the added hormones, and antibiotics in such meats. Not to mention grain fed meat that such to help make the meat fatter and heavier in weight, so to make more of it and increase sales. These should also be avoided at all cost!

    Shawna – I read under another thread that you used to feed Primal until you found they add hormones or something along that line. Well I used to feed commercial BARF patties (Still do, until I finish my dogs’ last box of the pork favoured ones), not because it contains added hormones, as Dr. Billinghurst guarantees in writing via his product guide, that his products are free of these, but rather because he literally, told me to f*** off during a recent phone conversation. He was basically cornered with regard to….. (Well I’d encourage you to read recent comments under the BARF thread here of the last 2 weeks, to get the whole picture), and hence whilst he may be highly educated in his fields, he lacks any customer service skill or people skills and therefore certainly does not deserve my business!

    It is always best to formulate ones own BARF meal using trusted sources of organic and grass fed meats and plant materials etc, as possible.

    Shawna – You are a very welcomed fellow like minded proponent to Shameless (Cathy) and I, that a third regular such proponent poster is so welcomed for that reason. Although there have been other irregular posters come and go that advocated the truth.

  • Gordon

    I’m not usually here at this time, but I’ve woken up early afternoon on a Saturday afternoon AEST and won’t be working tonight.

    Thunders Mom – Your situation is all too often the case. Kibbles and all processed dog foods for that matter, are a man made concept (Not Nature’s concept), born out of convenience, business, and these days, greed!

    All mainstream kibbles (including commercial holistic type kibbles, albeit lesser of evils) are so far away from what Nature intended for dogs or cats for that matter that they are as unnatural as possibly could be. There are so many expert anecdotal evidence (Never permitted or accepted as scientific evidence. i.e. a threat to the establishment) that mainstream grain, generic meat and bone meals (containing even euthanised dogs, cats, cattle etc, hence containing traces of pentobarbital and even sodium thiopental), most by-products unfit for human consumption, and high carbohydrate (A reversal of Nature’s rule on the amount of carbs dogs were meant to consume), riddled kibbles in fact, almost certainly have increased cases of pet cancers in the last 50 to 70 years.

  • Shawna

    I agree with Shameless…

    You can even get commercial products that are GREAT quality (pending the manufacturer is honest — which would be the case with kibble as well as raw).

    Bravo as an example —-
    “Our red meat products are hormone-free and grass-fed
    Our lamb and beef is 100% pure grass fed New Zealand lamb and beef. The result is a lean, rich red meat that is better for a pet’s health.
    Our poultry is antibiotic-free”
    http://www.bravorawdiet.com/bravodifference.html

    Poultry can not legally have added hormones so no worries about that… You can get “complete and balanced” diets from Bravo as well as component diets..

    Answer’s makes a great product too — including a raw goat milk… http://www.answerspetfood.com/sourcing.html

  • ShamelessRawFoodie

    Thunders Mom – I feed my dog mostly raw. I am very frugal, but also quality-conscious. Often, there is a way to get high-quality BARF ingredients, like pasture-raised meat, from farms near your area. Most of the smaller local farms are either certified organic or they use organic practices.
    http://www.eatwild.com/products/index.html

    Some meat deals can be found through some of the raw dog food co-ops. Some are ‘clean’ meat:
    http://www.dogaware.com/diet/rawgroups.html

    Costco sells a lot of organic foods for a fair price.
    Coleman Whole Organic Chicken $2.29/lb
    http://www.thethriftymama.com/2011/01/costco-organic-price-list.html
    http://www.thethriftymama.com/2011/05/organic-costco-shopping-trip-2011.html

    I also get some organic meat at my local organic market – chicken and turkey necks and backs for 50 cents/lb. Organic organs average around $2/lb.

  • Shawna

    Thunders Mom,

    I think you are right, there is no best choice. Hormones in meats are definitley a concern… However, kibble has its own set of risks.

    Dr. Demian Dressler DVM runs the dog cancer blog.com website and has written a book on cancer in dogs. He has an article on his website titled “Dog Food: Is There A Cancer Risk” then goes on to explain why ALL kibbles, even organic, increase the risks of cancer. http://www.dogcancerblog.com/dog-food-is-there-a-cancer-risk/

  • Thunders Mom

    After losing my beautiful German Shepherd to cancer I considered a BARF diet for my other dogs. But I became concerned about the level of hormones given to feedstock to increase weight and milk/egg production. Organic is just too expensive to be an option. I decided to go with Wellness Core as the best alternative for my pets. It seems like there is no best choice, but lots of bad ones!

    So are you saying that Taste of the Wild is not a good dog food? Face it it’s got to be better than Ole Roy, Alpo, or any of those other dog food out there that have less than 3 or 4 star ratings. I’ve been feeding TOTW for a couple of years to my APBT and she’s doing great on it. She’s been on it all of her life. She’s 2.5 years old.

    After reading the above , I got sick to my stomach . That’s the food I fed my last two dogs . I never had a clue . When we adopted our new dog , I started to research dog cancer and eventually ended up finding Mike’s site . Thank God for that and all the wonderful caring people that contribute to it . I only wish that Rusty and Roxy can forgive me for the crime I commited in feeding them Ole Roy .

    I feed my German Shepard Orijin and Acana – can anyone tell me if they use recycled food? Or confirm that they don’t? Thanks!

  • ShamelessRawFoodie

    Jane – People should heed your warning about consuming ‘secondhand recycled garbage from these rendering plants’, (although most Won’t, because they think they Can’t).

    For those who desire local meat and dairy that is as clean as possible on this toxic planet, for you and your pets, click this link – http://www.eatwild.com/ – where you can find “your source for safe, healthy, natural and nutritious grass-fed beef, lamb, goats, bison, poultry, pork, dairy…and other wild edibles.”

    And we wonder why something like 80% of dogs in the US die of cancer…
    Reading through the comments on this outstanding article (NOT news to me), I read a couple of questions about the cost of high quality kibble (I am not sure such a thing exists). For those with access to Costco, they have started carrying a brand called “Domain” reputed to be identical to Taste of the Wild.
    I also highly recommend this article:
    What’s Really in Pet Food http://www.bornfreeusa.org/facts.php?more=1&p=359

  • Jane Eagle

    “Every day, hundreds of rendering plants across America ship thousands of pounds of this recycled garbage to ranches, farms, feed lots… and pet food manufacturers.”
    So remember, boys and girls, that this is also fed to the animals you eat; you are just getting it secondhand :-(

  • Kris

    Given the fact that the pet food industry does sometimes use euthanized pets in their products, you should look beyond and consider why such practices are in place… why shelters knowingly allow their euthanized animals to be rendered.

    In many cases, these animals will be picked up & disposed of for FREE by rendering companies. Yes, they could simply cremate every animal they get but guess what — this costs money (operating the furnaces +/- labor costs). I personally opted to have every single one of my pets cremated & had their ashes returned to me. This may not be an issue either in smaller shelters which has a small coverage area, but how about in large cities & metros which may have to dispose of thousands of unwanted animals every year?

    I’m sure you won’t disagree that budgets are probably already running thin to support our local shelters. What other alternatives are available? dumping their dead bodies to further fill our local landfills?

    You don’t like the aspects of “recycling”, but what other cost effective way to deal with carcasses (not just of these pets, but also of the cattle, roadkill, etc). If everyone insists on feeding animals pure foods not derived from intentionally killed for food animals, then not only would it drive prices up and make owning pets unfeasible for a larger portion of the population but we would also be promoting the killing of more animals to support our + our pet’s carnivorous needs.

  • Peter

    Dogs and cats should not be given dry food at all, especially food containing cereals. Dogs are carnivores and should be eating a fresh raw meat diet including fish and eggs (inlcuding meaty bones!). Some shredded raw vegetable may be included but only very little to simulate the stomach of a fresh kill. Do a google search on BARF feeding and treat your pets with the nutrition and wholesome diet they deserve and stay away from ALL commercial dog food.

  • Gordon

    Interesting that you say that about Diamond Pet MRogers. That’s more often the vibe I’m getting from those who claim to be in the know, from other forums, regarding their Quality Control.

    That beggars the question Dr. Melissa Brookshire, formerly of Diamond Pet Foods, now a pet food industry consultant, and owner of her establish North River Enterpirses. I wonder if Robert’s (my cousin) emailed question to her was too difficult to answer? Surely answering all questions makes a significant part of a company’s Quality Control. Perhaps Diamond Pet’s former director Veterinary Services, should get another Vet to answer customer queries.

    Mary Lou, while I guess Tomato Pomace may be a problem, I do believe beet pulp is colorless.

  • Mary Lou

    I’m not sure where to place this comment, but wanted to share some results from personal experience with feeding our bichon. I had read early on, not to feed beet pulp to bichons because it contributes to tear stains. Our pup has been on Angels’ Eyes over time to rid him of tear stains. Since removing tomato pomace from his diet ~ no more tear stains!May be just a coincidence, but wanted to pass this on to those of you that may have white dogs. Thanks so much, Mike, for highlighting tomato pomace. Because of that, I began to look into this ingredient a bit more. In this case, it has been best to eliminate it from our dog’s diet.

  • Jonathan

    Smart dog. lol! No, but really, I’m glad you found this site. Have a look at some of the 3, 4, and 5 star dog foods. Be sure to transition to a new food by mixing it with the previous food for about a week.

    My dog stopped eating her pedigree last month and I been feeding her pedigree since she was a puppy 2 years ago.

  • Meagan

    Jenn- That is why we are all so happy that Mike Sagman has taken the time for this advisor site!

  • Jenn

    my dog recently stopped eating her pedigree dog food, they changed the recipe and this “meal” product is now the first ingredient, now i see why she refuses to touch it after 7yrs eating the prior ‘recipe’….this makes me completley sick this is even legal and something needs to be done about it. thats not right, and unsuspecting dog owners buy their dog food not knowing this could essentially be slowly killing their own pet…completely DISGUSTING that people will make product like this to save a few dollars…how do u sleep at night knowing that – ugh

  • MRogers

    Too bad that the general public chooses to ignore. In reality all manufactured food is suspect, most are obvious. By the way, i see here that taste of the wild is 5 star here. We used this for a while but learned that Diamonnd makes it. Although we had no problems with it Diamond has one of the worst quality control programs after Walmart. Recent corporate buyouts and interests will continue to bring quality down ….

  • Jonathan

    Jesse, you should see if there are any stores that carry Pro Pac. that is usually $25.99-28.99 for 33 pounds. Then there is Kirkland at Costco which I have heard is under $30 for 40 pounds. Also, Tractor Supply has 4Health around the same price. If you can find Diamond Naturals, that’s pretty much the same food as the previous two which are both made by Diamond. Also, keep in mind, your dog may eat LESS of a higher quality (as in more expensive) food, making the price difference a little more negligible. Good luck!

  • Meagan

    i just recently in the last 7 month became aware of the bad food out there. one is 7 years old b4 those 7 months for 6 years she had wal-mart food. i feel so bad for not knowing how horrible it is. i will never feed crap with my future pups

    Hi Jesse… The 3, 4 and 5-star foods on our lists can make an excellent choice. However, I’m not the pricing expert here. Maybe one of our other readers can help you pick a product in your price range. Wish I could be more help.

  • Jesse

    Hi –
    I’m just figuring out what to feed my pup, she’s 8 months old, and I’m starting to have to think about what sort of adult food to feed her. There are a million different “better” products out there and I have no idea where to even start when picking one for her. She’s extremely athletic, (She’s a Basenji with a little bit of terrier, and she is in love with agility) so I’d need something higher in fat and protein to keep her weight on, but I also want something that is good for her, and is going to give her a long happy life. Anyway, can you guys give me an idea of what is good? Something a college student on a budget could afford. (i.e., not $30-40/bag) Thanks!

    Hi Daniela… You’ve nothing to feel guilty about. Real food (meat, veggies, etc.) is always better than any factory-assembled “food-like” product. Harry is one lucky dog.

  • Daniela Desilets

    I wish I lived where meat was under a dollar a pound! I have a very energetic 60 pound Australian Cattle Dog and here in Canada’s north, it would cost $10.00 a day to feed him a diet of raw meat. He is on one of the 5 star grain-free dog foods evaluated on this site. I make sure he gets nice meaty bones every week, and add leftovers and when available and on sale, different kinds of meat. Even just the bones cost more than a dollar a pound.

    This week in addition to his Before Grain Chicken, he had beef kidney (raw), beef heart (cooked) and 2 bones to gnaw on, plus strawberries, avocado, banana, broccoli and mushrooms.

    There is no way I could afford to feed him raw all the time. Harry is high energy and needs “jet fuel” to keep weight on, and he is allergic to grain. I fed my old female raw, and homemade, but she was the “easy keeper” type.

  • Carrie

    I do not know how anyone could come in defense of feeding their animals anything but good quality foods. If you cannot afford decent food for your pets you should not have pets. That is just selfish. Would you adopt a child if all you had to feed it was trash?

    Feeding raw of gently cooked foods is actually very inexpensive.
    Meat can be gotten at the grocery for under a dollar a pound. An 80lb dog only eats two pounds a day!
    As far as manufactures not being able to get enough quality meat to manufacture foods if we stopped this abhorrent practice if rendering, that is ridiculous. The meat is available.
    Where do these people come up with this garbage?
