BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) are synthetic preservatives that have been used for many years to help prevent fats and oils from becoming rancid. They extend shelf life and help maintain the flavor of some pet foods and treats.

The use of these preservatives has been debated for decades. Some laboratory animal studies have raised concerns about possible health effects when large amounts were consumed over long periods. Because of these findings, many pet owners choose foods preserved with natural alternatives whenever possible.

It is important to recognize that laboratory studies do not always reflect the way companion animals are exposed to these ingredients in commercial pet foods. However, many holistic veterinarians and pet nutritionists believe there is little advantage to using synthetic preservatives when effective natural alternatives are available.

Today, many premium pet food manufacturers preserve their foods with mixed tocopherols (a natural form of vitamin E), rosemary extract, or other naturally derived antioxidants instead of BHA and BHT.

When reading a pet food label, look carefully at both the ingredient list and the preservative statement. BHA and BHT may appear by name or may be listed among the preservatives used to protect fats and oils in the food.

Pet owners who prefer to avoid synthetic preservatives should look for foods that specifically state they are preserved with mixed tocopherols or other natural preservatives.

Choosing a high-quality diet involves much more than avoiding one or two ingredients. The quality of the protein sources, the overall ingredient selection, the manufacturing practices, and the company's commitment to nutritional excellence are all important considerations.

For this reason, I encourage pet owners to select diets made with wholesome ingredients and natural preservation methods whenever practical. While BHA and BHT continue to be permitted in some pet foods, many excellent products are now available that do not rely on these synthetic preservatives.

Key Points:

• Read ingredient labels carefully.
• Choose foods preserved with mixed tocopherols or other natural preservatives whenever possible.
• Evaluate the overall quality of the diet rather than focusing on a single ingredient.

If your pet has a medical condition, consult with your veterinarian or a qualified pet nutrition professional before making significant dietary changes.
