What is BHA and Why Is It Used in Some Bacon?
Butylated hydroxyanisole, or BHA (E320), is a synthetic phenolic antioxidant used in the food industry to preserve products containing fats and oils. Its primary function is to prevent oxidation, a chemical process that causes fats to spoil, leading to off-flavors, unpleasant odors, and changes in color. For bacon manufacturers, this means extending the product's shelf life, ensuring flavor stability, and preventing rancidity.
While BHA is not present in all bacon, it is sometimes added to specific types, particularly pre-cooked bacon and rendered bacon grease products. The fat content in bacon makes it susceptible to oxidation, and BHA acts as a chemical scavenger of free radicals, effectively delaying the spoilage process. However, its use is optional and many companies now produce bacon without this additive, relying on alternative methods like natural preservatives or flash-freezing.
The Difference Between BHA and Curing Agents
It is important to distinguish BHA from the curing agents traditionally associated with bacon, such as sodium nitrite. Curing is the process of preserving meat by using salt and other additives. Traditional cured bacon uses synthetic sodium nitrite, while products labeled "uncured" use natural sources of nitrates, like celery powder, which still convert to nitrites during the curing process. BHA is a separate additive and not a curing agent itself, though it may be used in conjunction with other preservatives in some products. The presence of BHA is not dictated by whether the bacon is "cured" or "uncured"; consumers must check the ingredient list for BHA specifically.
Health and Regulatory Controversies Surrounding BHA
The safety of BHA has been a subject of ongoing debate for decades. While the U.S. Food and Drug Administration (FDA) has classified BHA as "generally recognized as safe" (GRAS) for use in food at a maximum concentration of 0.02% of the fat content, this status is controversial.
- The National Toxicology Program (NTP) has listed BHA as "reasonably anticipated to be a human carcinogen" since 1991, based on studies where high doses caused tumors in the forestomachs of rats, mice, and hamsters.
- Concerns have also been raised about BHA's potential to act as an endocrine disruptor, affecting hormone function.
- Unlike the FDA's position, other countries and regions have taken stricter measures. BHA is banned in several European countries, the UK, and Japan, which follow a precautionary principle requiring additives to be proven safe before approval.
How to Tell if Your Bacon Contains BHA
The most reliable way to know if a bacon product contains BHA is to read the ingredients list on the packaging. Federal regulations require that food additives are clearly listed. Look for "BHA" or "butylated hydroxyanisole" in the list of ingredients. Many brands, particularly those marketing themselves as "natural" or "clean label," will explicitly state "no BHA," "no artificial preservatives," or similar claims on the front of the packaging.
BHA vs. Natural Preservatives: A Comparison

Is BHA in bacon? A Closer Look at the Controversial Additive
Butylated hydroxyanisole (BHA) is a synthetic chemical antioxidant sometimes used as a preservative in certain food products, including some bacon. Its purpose is to prevent fat from becoming rancid and spoiling, thereby extending the product’s shelf life. However, the use of BHA is a subject of debate due to health concerns raised by various studies. While the U.S. FDA deems it safe in small amounts, other countries have banned it entirely.
The Role of BHA in Food Preservation
BHA works by acting as an antioxidant, scavenging free radicals that initiate the oxidation of fats and oils. This process is crucial in prolonging the freshness, flavor, and color of fat-containing foods. For products like bacon, which have a high fat content, preventing this oxidation is a key part of the manufacturing process to ensure consistent quality and a long shelf life. BHA is especially effective in cooked or pre-cooked items where the preservation needs are more immediate.

What is BHA? Understanding the Additive in Some Bacon Products
Butylated hydroxyanisole (BHA), also known by its European food additive code E320, is a synthetic antioxidant. It is often used in processed foods that contain fats and oils, such as some types of bacon, to prevent rancidity. By inhibiting the oxidation process, BHA extends the product's shelf life and preserves its flavor and color. While the U.S. Food and Drug Administration (FDA) has classified BHA as "generally recognized as safe" (GRAS) within specific limits, its safety is a subject of controversy due to animal studies linking it to potential carcinogenicity.
Reading the Labels: How to Tell if Your Bacon Has BHA
To determine if your bacon contains BHA, you must examine the product's ingredient list. All food additives are required to be disclosed on the label. Look for the specific term "butylated hydroxyanisole" or its acronym "BHA." Many brands that do not use BHA will advertise this prominently on the packaging, stating "no artificial preservatives" or similar phrases. Furthermore, remember that the "uncured" label indicates the use of natural nitrates for curing, which is separate from the potential use of BHA.
The BHA Debate: Health Concerns and Global Regulations
The health risks associated with BHA are a significant reason for consumer concern. The National Toxicology Program has classified BHA as "reasonably anticipated to be a human carcinogen," based on animal studies. Additionally, some research has suggested BHA may act as an endocrine disruptor. In contrast to the U.S. FDA's GRAS designation, which is based on older data, many other countries, including several in Europe and Japan, have banned BHA. These different approaches reflect the ongoing debate about the long-term safety of BHA consumption.
