BHA and BHT in Pet Food: The Truth Every Pet Parent Needs to Know

Learn why BHA and BHT are dangerous preservatives found in pet food, the science behind their risks, and how to choose safer alternatives for your dog or cat’s long-term health.

🧫 What Are BHA and BHT in Pet Food?

BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) are synthetic preservatives used to extend the shelf life of fats and oils in pet food. While this might sound harmless, these ingredients come with serious health concerns for pets—and humans, too.

These chemicals are still found in many mass-market pet food brands, especially lower-cost dry kibble and treats. Their job? Keep fat from spoiling. But what’s the long-term cost to your pet?

⚠️ Are BHA and BHT Safe for Pets?

The short answer is no. These preservatives have been linked to cancer, hormone disruption, and organ damage in scientific studies.

🔬 BHA: “Reasonably Anticipated to Be a Human Carcinogen”

According to the National Toxicology Program, BHA has been shown to cause tumors in the forestomachs of rats and hamsters. While those studies were conducted on rodents, the concern for long-term exposure in pets remains valid—especially since dogs and cats eat the same food daily.

BHA has also been linked to:

• Kidney dysfunction
• Liver enlargement
• Behavioral changes in lab animals

🧪 BHT: Hormonal Disruptor & Organ Toxicant

BHT has been studied for its ability to interfere with hormones. According to Everyday Health, BHT may:

• Disrupt the endocrine system (hormone balance)
• Affect thyroid function
• Cause liver and kidney damage in animals

Even though some regulatory agencies consider BHA and BHT “safe in small amounts,” pets are exposed to them daily over years. That adds up.

🌍 What Do Other Countries Say?

Many European nations have banned or heavily restricted the use of BHA and BHT in food products, including pet food. In the U.S., these additives are still widely used—despite concerns and outdated safety data.

🐶 Why This Matters So Much for Your Pet

Unlike people, pets eat the same formula of food day in and day out. If that food contains toxic additives like BHA or BHT, the exposure isn’t just occasional—it’s constant.

Your pet’s body doesn’t get a break from these ingredients. And over time, the risks compound. Chronic exposure to these additives has been associated with:

• Increased cancer risk
• Immune dysfunction
• Organ stress and inflammation

✅ How to Avoid BHA and BHT in Pet Food

Making better choices doesn’t have to be overwhelming. Here’s where to start:

🛑 Check the Label

Avoid any food or treat that lists:

• “Preserved with BHA” or “BHT”
• Generic terms like “artificial preservatives”
• “Animal fat preserved with BHA/BHT”

🍃 Look for Natural Preservatives

Safer alternatives include:

• Mixed tocopherols (Vitamin E)
• Rosemary extract
• Ascorbic acid (Vitamin C)

🧾 Choose Transparent Brands

Buy from companies that are clear about what’s in their food and why. If they don’t disclose full ingredients or avoid questions, that’s a red flag.
