The Misleading Label: Understanding "Uncured" Bacon
When you see a package of bacon labeled "uncured" or "no nitrates or nitrites added," it's important to understand what this really means. By law, a product can only be called "cured" if it uses synthetic sodium nitrite to preserve the meat. Brands that use naturally occurring nitrates from vegetable sources, like celery powder, are required to label their product as "uncured," even though it has gone through a curing process.
This labeling distinction can be confusing for consumers who assume "uncured" means a complete absence of nitrates. In reality, these natural nitrates are converted to nitrites during the curing process, and the final product can have similar nitrite levels to traditionally cured bacon. The key difference lies in the source of the preservative, not its presence or absence.
How Natural Nitrates are Used
Instead of a direct injection of a synthetic chemical, uncured bacon is cured using natural substances. The most common of these is celery powder or juice, which is rich in nitrates. When this powder is added to bacon, it interacts with bacterial cultures to create nitrites, which then act as the preservative. Other natural ingredients like sea salt and beet juice can also be used. The USDA requires these products to carry a label stating, "no nitrates or nitrites added except those naturally occurring in ingredients like celery powder".
Brands of Uncured Bacon
Many brands now offer uncured varieties to meet consumer demand. Here are some examples to look for on your next grocery trip:
- Applegate: A popular and widely available brand that offers several varieties of uncured, organic bacon.
- Hormel Natural Choice: This line from Hormel includes uncured original bacon and is available in most major supermarkets.
- Naked Bacon: A specialty company focusing on bacon with no sugar, nitrates, nitrites, or celery powder, using herbs and spices for flavor and preservation.
- Tender Belly: Cures their bacon with a dry rub of celery powder and sea salt.
- Broadbent Hams: Known for dry-cured country products, they offer a nitrite-free bacon option using simple ingredients like salt and sugar.
- Reber Rock Farm: An example of a specialty brand that explicitly states their product is truly nitrate-free, using only salt and sugar.
Cured vs. Uncured Bacon: A Comparison
| Feature | Cured Bacon | Uncured Bacon | 
|---|---|---|
| Curing Agent Source | Synthetic sodium nitrite | Natural sources like celery powder or beet juice | 
| Labeling | Labeled as "cured" | Labeled as "uncured" and "no nitrates or nitrites added..." | 
| Final Nitrite Level | Can be similar to uncured bacon after processing | Varies, but still contains naturally derived nitrites | 
| Appearance | Maintains a distinct pink color for a longer time due to synthetic preservatives | May turn gray more quickly when exposed to air | 
| Primary Preservation | Extends shelf life with synthetic agents | Extends shelf life with natural agents | 
| Health Implications | Potential for nitrosamine formation during high-heat cooking | Potential for nitrosamine formation during high-heat cooking, although natural antioxidants may help | 
The Health Debate: Separating Fact from Hype
For many years, synthetic nitrates in processed meats were linked to the formation of nitrosamines, which are considered carcinogenic. The industry's move to natural curing agents like celery powder was a response to this concern, with the assumption that "natural" is healthier. However, the scientific community has pointed out that a nitrite molecule is chemically identical whether it comes from celery or a lab. Studies have shown that natural nitrites, when exposed to high heat with proteins, can also form nitrosamines.
Some vegetables contain protective compounds like Vitamin C, which can mitigate nitrosamine formation. However, the benefit is not absolute, and experts caution that the overall health impact may not be significantly different between uncured and cured bacon. The key takeaway is that moderation is essential, regardless of the curing method. Consumers should be aware that the "uncured" label does not necessarily mean a nitrosamine-free product.

Making the Best Choice for You
Ultimately, the choice between cured and uncured bacon depends on your priorities. If you are focused on avoiding synthetic chemicals, brands labeled "uncured" that use celery powder or other natural agents are the correct choice. If you are concerned with nitrites in general, regardless of their source, you may want to seek out the rare specialty brand that avoids any form of curing agent besides salt and sugar, like Reber Rock Farm, or opt for healthier alternatives altogether.
For most people, the difference in taste is minimal and more dependent on the cut, seasonings, and smoking process than the curing agent. By understanding what the labels truly mean, you can make a more informed decision for your diet and preferences, remembering that bacon, cured or uncured, is a food best enjoyed in moderation.
