Natural and Artificial Preservatives in Dog Food – Preserving ..

Commonly used artificial preservatives in dry dog foods include ethoxyquin, butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). They are very effective at preventing fats from becoming rancid (the primary problem we face in preserving dry dog food) and can greatly extend the product’s shelf life (a year is typical). On the other hand, some studies have linked the ingestion of large amounts of ethoxyquin to health problems. While there is certainly no "smoking gun" out there indicating most pets need to avoid the levels of artificial preservatives currently present in dry food, out of an abundance of caution, many owners understandably prefer to avoid feeding them to their dogs.

well I hope a study is done soon this bha needs banning in dog food,I use acana food.

Hi Darryl… The answer to all your questions can be found right here on this website. Look in our Library for articles about other problem ingredients in addition to BHA. And there are hundreds of dog food reviews I’ve arranged according to their star ratings. Unfortunately, I cannot provide customized reviews and product recommendations for each reader. For more information, please check out my reviews and visit our . Look for the topic, “Help Me Choose a Dog Food”. Or check back for a possible response from one of our other readers. Wish I could be more help.

Aug 17, 2013 - Do you have your dog's food label in front of you

Unfortunately, both BHA and BHT can still be found in a number of commercial dog foods. Is there a definitive list of foods containing the bha range of chemicals ? I suggest a simple list is constructed,the sooner a list is printed the better,dog treats included.

BHT, even more potent than BHA, is used to help reduce food spoiling

BHA Enhanced stomach and urinary bladder carcinogenesis


However, the FDA allows BHA to be added to human food (and dog treats) at certain levels and classifies the preservative as “generally regarded as safe.” The idea is that although BHA might cause cancer in lab rats, its metabolized differently by other animals —humans and dogs in particular — and it’s used in foods at amounts well below levels that would cause problems. Still, the :Check the kind of preservative used in your pet’s food. While most manufacturers have switched to natural preservatives like vitamin C, vitamin E or tocopherols, some foods and treats still use chemical preservatives, including BHA, BHT and ethoxyquin. Whole Dog Journal notes that BHA and BHT have been linked to cancer in laboratory animals, though it’s unknown whether they are equally carcinogenic in people and pets. The publication also points out that manufacturers have favored artificial preservatives because they preserve food longer and are cheaper. If you choose naturally preserved food, be ready to pay a bit more, and don’t buy a huge bag for a small dog — while food past its prime may not make your dog sick, it may lose nutritional value over time.
