The Case AGAINST Raw Frozen Pet Foods

12 Nov

For some twenty five years I actually have alerted the general public to the hazards of solely feeding heat processed foods. Companion animal feeding has progressed – really digressed – from table scraps and real foods the family might spare to today’s “100 p.c complete” processed foods in primarily kibble type, with some canned and semi-moist additionally on the market. The foods seem to be scientific and improved, however they’re so much worse for the animals. Not solely is nutrient worth diminished by heat, however a spectrum of poisons is formed. Additionally, the singular feeding of processed food has led to the spurious “100% complete and balanced” claim that’s each logically and scientifically flawed.
Entrepreneurs have seized upon this data to make a spate of raw frozen (RF) foods to capture a market niche and to fill the demand from shoppers wanting a raw various to straightforward heat processed canned, semi-moist and dried pet foods. This market trend, like most others, might begin with some truth (raw food is that the best food) however gets distorted, if not perverted, once economic chance enters the image. This paper can examine the rationale of those merchandise, their economics and dangers. A additional intelligent and healthy various are proposed.


1. Weakened Pets And Highly Virulent Organisms – A raw state and also the presence of moisture in food give the right atmosphere for the expansion of pathogenic organisms. though prey foods within the wild usually putrefy and are teeming with microorganisms, carnivores within the wild are immunologically tailored to those organisms and even like the probiotic effects of some. On the opposite hand, domestic pets eating sterilized heat processed foods are immunologically compromised and are threatened by mutated and highly virulent pathogenic strains created by fashionable circumstances and antibiotic resistance. Freezing at acceptable temperatures puts pathogens during a state of arrest however doesn’t eliminate them. though all foods contain some pathogens, unless they’re sterilized (requiring high heat or different measures that greatly diminish the nutritional worth and make toxins), it’s the load of those pathogens that has got to be of concern to shoppers. RF foods are a possible reservoir and vector of enormous numbers of pathogens.

2. Producers With solely Kitchen Technology – thanks to the minimal technology needed to supply a RF pet food, basically anyone despite credentials or experience will bring a product to plug. All one must do is grind and blend ingredients during a kitchen, package and place during a freezer. There are not any controls over the conditions within the kitchen, the standard of the ingredients or the tactic of freezing. of these factors will dramatically influence the nutritional worth and pathogenic and toxic content of the food. however being during a frozen state hides these potential dangers and so poses a threat to each pets and also the humans who handle the foods. John Doe will build a food beneath unknown conditions and with unknown ingredients, label, package, freeze and deliver to shoppers or stores while not one single management monitoring or impeding the method. Regulators might eventually examine the label if they happen to examine it during a store (they can never see it if shipped on to consumers) and object to some terminology or the like; however, all John must do is amendment the label and every one are well. the merchandise might contain each manner of ingredient, be laced with virulent pathogens, and receive the aegis of regulators … and into the put up for sale goes.

3. Raw Frozen Foods aren’t “100% Complete” – several RF foods build (or imply) an equivalent spurious 100% complete claim as heat processed foods and so carry with them an equivalent health dangers. Feeding any food solely, as well as a nondescript packaged food containing who-knows-what from who-knows what producing atmosphere, could be a dangerous alternative if health and safety are of concern. (See the reality concerning Pet Foods by Dr. Wysong).

4. issues Are Ignored By Producers – RF food pathogens embody not solely bacteria, but fungi, viruses and parasites. Toxins embody those from molds (mycotoxins), bacteria and people created by oxidation. In our study of RF merchandise within the stream of commerce, not one producer addressed these issues with any technological know-how that we have a tendency to might discern, and most failed to even acknowledge the issues probably lurking in their foods.

5. Freezing Masks Inedibles – Raw meat and organ tissue continues to use ATP (source of energy) till it’s exhausted and also the tissue enters a state of rigor. Endogenous enzymatic activity at intervals the tissue continues to digest the muscle tissue (proteolysis), softening it till it becomes tender and develops the standard palatable style. This method is retarded by cold. The freezing of properly aged meat presents few issues, however, any residual ATP gift within the tissue throughout freezing can contract the muscle upon thawing leading to a additional unpalatable product. Mixed RF foods would hide this drawback.

6. Free Radical issues Masked – Essential fatty acids and different health enhancing lipids are vital within the diet. Once foods are ground, mixed, exposed to air, light-weight and pro-oxidants like heme iron and different metals found in plant and animal tissue, the contained lipids are oxidized to chain reaction manufacturing free-radicals, inflicting rancidity and oxidant toxins. Freezing at appropriately low temperatures slows this method however doesn’t stop it. The temperature in typical freezers used for RF foods isn’t insurance against such oxidation. as a result of the frozen state masks olfactory detection of rancidity, foods that will be otherwise rejected find yourself being consumed. The free-radical pathology potential will then work its chronic muscular disease and immune weakening effects.

7. Freezer Burn Indicates A additional major problem – Air reaching the meat surface is that the cause for the freezer burns that lead to the standard grayish-brown leathery spots. Frozen water on the surface or simply beneath it sublimates (from solid state on to vapor) into the air, inflicting moisture to be lost from the meat over time leading to discoloration and a dry, leathery texture. correct packaging helps maintain quality and stop freezer burn, but most packaging is permeable to air. The prevalence of freezer burn in RF merchandise speaks to the very fact that the merchandise is being oxidized and with that making free radical toxins to get the seeds for numerous degenerative diseases.

8. show Packaging Causes Free Radicals – light-weight, likewise as air, will promote free radical production. Retail show packaging that’s clear or light-weight permeable permits light-weight to catalyze the free radical (disease promoting) method.

9. Frozen merchandise aren’t Inert To Degradation – In frozen storage there’s deterioration in organoleptic quality – meat texture, fat turning granular and crumbly, and discoloration. Microbial enzymes additionally stay active, particularly lipases that break down fats increasing their susceptibility to oxidation.

10. Frozen Foods will result in Acidemia – Tissue degradation and oxidation beneath high heat freezing (above 29° F), that happens along the availability chain with most RF merchandise, additionally ends up in acidification. Increasing acid consumption will contribute to acidemia that lies at the bottom of just about each chronic muscular disease plaguing fashionable pets. (See reference below.)

11. Temperature And Time Are vital – Ice nucleation, as hostile ice crystallization, is that the primary vector in manufacturing a stable, tasty, frozen product. Freezing could be a technically advanced method primarily based on the optimum combination of temperature and time, amongst different factors. within the wrong processor’s hands, slips in correct freezing care will result in a microbiologically unstable product and/or a sensory inferior one. speedy freezing ends up in nucleation, thereby preventing undesirable massive ice crystals from forming throughout the merchandise. With speedy freezing the molecules don’t have time to create positions within the characteristic six-sided snowflake, thus nucleation overrides crystallization. On the opposite hand, slow freezing (the usual RF situation) creates massive ice crystals, that on thawing causes cellular injury to the meat. This in flip causes meat to “drip” – lose juiciness – and type an ideal liquid medium for bacterial growth.

12. The High Risk In Thawing – Thawing is another vital part within the freezing method because it involves a amendment from crystal ice to melted water, that upon reabsorption leads to microbial reactivation. Pathogenic bacteria inherently contaminate raw meat, fish, and poultry and can begin to multiply once more when the temperature reaches simply twenty nine.3º F – that is below freezing! so a product that will seem subjectively frozen may be a veritable incubator of pathogens. When shoppers commit to thaw RF foods, dangers dramatically increase. The surface temperature rises long before the inside is sufficiently thawed to serve. as an example, it takes concerning fifteen hours for the center of a 22-pound turkey to induce to 32º F. within the interim the surface temperature rises to 53º F. during this quantity of your time there would be concerning four multiplications
of spoilage bacteria likewise as non-detectable multiplications of pathogens. The FDA Model Food Code (1999) recommends that food be thawed within the refrigerator or in flowing water. Thawing RF food within the refrigerator are often inefficient and time consuming, additionally to occupying refrigeration house needed for different food things. Most of all, this lengthy procedure will result in the danger of cross-contamination when the drip from the raw meat comes involved with ready-to-eat food stored within the refrigerator. within the various, shoppers sometimes place the RF food out at area temperature, making the right circumstance for pathogen proliferation.

13. Undetected Freeze-Thaw Cycles – The transit time of RF food from the processor (or John Doe’s kitchen) to the distributor, to the stores and eventually to the buyer is extremely vital. though freezer delivery trucks may putatively maintain stable product temperatures, lack of thermocouples fitted within the truck to point out temperature readings, and/or inadequate TTIs (time-temperature indicators) will result in microbiologically infested merchandise with none visible spoilage signs. If the refrigeration in any a part of the availability chain fails briefly and then goes back to frozen (freeze-thaw-freeze), the buyer would never understand of this abuse and danger.

14. offer Chain Time Dangers – Time is that the enemy of nutrition and safety. The longer the time between the farmer’s field and also the belly, the larger the potential issues. RF foods produce the illusion that point isn’t an element. as a result of the frozen state masks toxins and odors, the buyer are often given the impression of worth and freshness when, in fact, they’ll be obtaining age and toxicity.

15. Microwave Thawing Dangers – If RF foods are thawed within the microwave as a matter of convenience, the worth of the food is greatly compromised. Microwaves will just about boil the liquid part at intervals cells and electromagnetically alter vital food parts rendering them not solely useless nutritionally, however toxic likewise.

16. Mycotoxins Go Undetected – RF foods, notably people who are a combination of cooked grains (which after all negates the claim for “rawness”) and vegetables, will contain mycotoxins. None of the producers surveyed addressed this drawback.

17. Frozen Product Mixtures build No Health Sense – In an effort to hide each conceivable base and not miss any chance for profit, several RF producers combine each manner of ingredient. as an example, watermelon, grains, persimmons, liver, lamb, etc. Not solely would creatures within the wild never eat such a mixed gruel at one sitting, such mixtures within the contemporary state will cause serious digestive stress. several of the exotic RF ingredients don’t keep well within the contemporary frozen state (for example, freeze watermelon alone and see what happens, as well as combining it with meat). Also, the mix of fruit sugars with proteins will probably produce toxins like glycation finish merchandise, acrylamides (particularly in those “RF” foods containing cooked carbohydrates) and reaction merchandise of proteins with plant tannins, phenols and flavonoids. Producers “throwing the book” at RF formulations in desperate makes an attempt to capture
market share build evident their motives and their scientific, health and technical naiveté.

18. Parasites Are Ignored – a large vary of parasites are often found at intervals RF foods. though there’s technology in terms of freezing and natural ingredients that may be used to thwart this drawback, none of the producers examined used any of it that we have a tendency to might detect.


The best packaging for any food, notably RF foods, is light- and oxygen-barrier and changed atmosphere flushed. within the absence of this, oxidation proceeds rendering the lipids toxic. None of the producers surveyed used these technologies that we have a tendency to might detect. albeit they did, the opposite issues and dangers listed higher than would stay.


We live in an age of pollution and energy diminishment. RF foods need an amazing quantity of refrigeration and equipment all along the availability path. Freezing is energy inefficient and consumes valuable energy resources. Since RF foods are seventieth water (at least) there are huge resources wasted in freezing and transporting the a lot of this food-contained water through the availability chain. beside all the equipment, trucking, freezing and frozen water handling inefficiency comes the pollution that parallels such business.


In order to form their foods anywhere close to reasonable, RF producers should search the ingredient marketplace for things {that can|which will|that might} carry the name of real food however may actually be solely a hollow shell of the $64000 factor. Inferior meat and organ ingredients, heat processed grains and vegetable riffraff (for example “broccoli” on a label might very be broccoli stems – like eating a branch from an apple tree instead of the apple) are used as a result of they’re of low value. that’s to not say the promoting brochures and labels don’t build it seem as if the complete isn’t a real connoisseur meal. If one reviews the assorted labels it becomes clear that the race is on to examine who will place the fanciest and most exotic ingredients on labels … as if that’s the road to pet health. (It is not.) during a transient ingredient survey this can be what we have a tendency to found:

Every manner of “pureed” vegetable

Organic beef, rabbit, chicken, turkey, goat, lamb, duck, pork

Organic honey

Organic papaya, persimmons, blueberries, oranges, apples, pears

Organic yogurt

Organic alfalfa, millet, quinoa and barley sprouts

Wheat grass


Bok choy

Cultured kefir

Cod liver oil



The reader is challenged to travel to the shop and total up the value of such ingredients. a number of the organic ingredients will value over $15 per pound. however the RF diets containing them will retail for as very little as $2-4 per pound. subtract margins for distributors and retail stores and also the producer is selling them wholesale for near a dollar per pound. currently on prime of the value of ingredients is that the production, advertising, packaging, freezing and in some cases a sales force creating six figures. one thing most actually doesn’t add up. the sole factor that may be missing is true ingredient quality. however how will the label say these expensive ingredients are within the food? All the producer must do is place in pinches of the expensive ingredients simply to mention they’re there.

The only economic hope for a RF producer is to make the perception of “value added.” They merely couldn’t place the expensive ingredients within the food to any degree and build a profit for themselves and every one the middlemen up and down the chain. the worth they might ought to charge would be ridiculous. In effect, so as to achieve success, producers should become accomplished at propaganda, not health and nutrition.

Consumers inquisitive about cutting through to the reality do themselves and their pets a service by getting to the grocery with a listing of the ingredients ostensibly during a RF diet. though some RF diets within the lower cost vary seem to not be trying to mislead, shoppers ought to do the maths comparing the exotic ingredients in
RF pet foods to the costs for the $64000 factor within the store and choose for themselves whether or not either worth or honesty resides in RF merchandise.


Consumers are beneath the mistaken assumption that a nondescript package mixture of ingredients with an officious label and from a producer posing as a nutritional authority (none of the producers we have a tendency to examined had folks at the helm with experience or credentials) would be the simplest alternative. very little do they notice that they might avoid basically all of the caveats listed higher than by merely getting to the grocery store and shopping for contemporary meats and manufacture. Pets don’t need each nutrient existing at each meal, as is that the impression given by the 100% complete RF producers, and for that matter the remainder of the pet food business. Why would folks like better to pay a producer to combine inferior ingredients, package them, label them, freeze them, transport them, advertise them and pay the margin for the producer, the distributor, sales force and also the retailer after they will avoid all that value and place their cash into real quality contemporary foods? Some folks are thus convinced that RF makers perform some kind of magic that they’re going to pay to possess such foods place in special insulated containers full of dry ice and overnight delivered! this can be notably ridiculous when one considers that no real convenience – and definitely no health or nutritional worth – is added within the method. geter|the patron} still should move to the shop and buy one thing.

At the grocery store an individual should buy contemporary, raw, untainted meats and manufacture acceptable for pet carnivores at but $1 per pound. Slightly out-of-date meats, sale items, trimmings or different still wonderful merchandise that can’t be place within the meat case are often even less. True, if you’re to buy the ingredients listed higher than in excellent human grade organic type (as several RF producers boast) the value may be so much larger. however a minimum of you’d understand what you’re obtaining. RF foods will value the maximum amount as $7 per pound with a median of concerning $3-4 per pound (not together with shipping to the customer’s door) and most of that value goes into freezing, transportation and profits through an entire chain of participants. Here could be a case where a shopper gets to pay heap of} (a whole ton more) and acquire less (a whole lot less). Isn’t promoting an exquisite thing?

A Better various

Fresh foods fed in selection are while not question the right kind of nutrition. Appropriately designed supplements to assist scale back the danger of food-borne pathogens and oxidation, and to assist balance high meat meals and supply a spectrum of vegetable-based nutrients and nutraceuticals also can be of nice profit. something but this can be a compromise. following best various is packaged dried raw foods that have incorporated in them food technology to impede pathogens, parasites and oxidation. The low water activity of those merchandise could be a nice inhibitor of pathogens and also the low level of moisture build storage and shipping economical and environmentally friendly. sensible quality table scraps and properly designed dried extruded and canned foods are often mixed into the diet rotation with profit likewise.

Consumers should learn the principles of contemporary foods fed in selection and to trust in nature. each pet owner needs the simplest for a beloved pet, and is correct in thinking food is an important component in achieving that goal. however it’s incorrect to believe that another person will do additional for his or her pet’s health than they’ll do themselves. All that’s needed could be a very little understanding and use of sense.
