Natural and Artificial Preservatives in Dog Food – Preserving ..
Ethoxyquin is a fat preservative sometimes used in dog food that has garnered a controversial reputation.
The food should be preserved naturally with vitamin E (tocopheral), vitamin C, or oils of rosemary, clove, or other spices. Natural preservatives do not provide as long a shelf life but are generally safer (make sure that you buy your food from a store with a quick turn-over. Read the date code on the bag to determine how fresh the food is - 160206 or 021606 means made on February 16, 2006. 10206 or 1026 means made on the 102nd day of 2006. Best before 2/16/07, probably means it was made on February 16, 2006. If the bag shows grease on the outside, do not buy it. Always return food that smells rancid, appears moldy, or seems unfresh in any manner. Never feed it to your dog).
is another preservative commonly found in many dog food brands. This preservative is a by-product of herbicide. The herbicide is a chemical used to kill unwanted vegetation, and when added to dog food it damages its liver and kidneys. This preservative also causes cancers, immune deficiency syndrome, leukemia, blindness, and much more. This harmful chemical present in any dog food could potentially kill your GS.

Under a typical pet food diet, the average dog (44 lbs) can consume 26 lbs of preservatives a year! The FDA currently allows only a trace amount of ethoxyquin residue (.5 to 5 ppm) in human consumed foods, yet it allows high amounts (150 ppm) to be used in pet food and livestock feeds. Of note, in 1997, the FDA's Center for Veterinary Medicine (CVM) made a request to manufacturers of ethoxyquin and the pet food industry to voluntarily lower ethoxyquin residue in pet foods to 75 parts per million (ppm). To date, there is still no mandatory requirement to meet the voluntary request.Yes, the research article states that rosemary oil should never be taken orally, and the reason is, is that it is a volatile oil...like many herbs, and volatile oils are not the form that is used for eating, it is the form used as a natural preservative, massage oils or fragrance oils. It would never be a form that is used in a dog food anyway, it would be a powdered form from dried leaves and it would be in tiny amounts along with other botanicals, which is evident by its placement on the label - provided one know how to read a dog food label.The use of Rosemary as a natural preservative in dog foods has come under question due to misinformation that has been generated on the internet.
In this article I want to explore this topic and get all this into perspective. I received another email today questioning the use of rosemary extract in pet foods stating, that this owner read on the internet that it is a neurotoxin and can cause seizures.
Like most things in life, nothing is black/white but when these things get started on these discussion lists, they seem to develop a life of it's own. Often this is where pet nutritional information is regurgitated by individuals who are not credible nor knowledgeable, and information is inaccurate, misinterpreted and/or taken out of context. Such is the case with the information about "rosemary".
Many pet discussion lists and general pet care websites are organized by individuals who love their pets. And under the pretense of gathering information to help other pet owners, they do not have the knowledge to discern what is accurate or inaccurate information before posting it to their websites. Such as the case of one particular website that has an article posted on it concerning the herb, rosemary. Rosemary has been used in natural pet foods for over 20 years, the amount that is used in the foods is an miniscule and not a volatile oil extract. If it were a problem, after all these years, AFFCO and the natural/holistic pet food industry and breeders would have know it by now.
Actually, you can use 1 drop of rosemary oil extract (antioxidant) to a gallon of olive oil it will prevent it from going rancid, a chemical reaction which is by far more toxic to the body than the minuscule amount of rosemary oil. Yet an ounce of it consumed can be a problem for humans or pets.
Rosemary has not been studied in children for medicinaluses in therapeutic dosages, which are much stronger and higher quantities than ever used in dog foods or when eaten. It is safe to eat as a spice in food, and it is safe to use in miniscule amounts for a preservative.
