Understanding Nitrates and Organic Standards
Nitrates are chemical compounds composed of nitrogen and oxygen, found naturally in soil, water, and many vegetables. For centuries, nitrites and nitrates have also been used in meat processing as curing agents to extend shelf life, prevent bacterial growth (especially Clostridium botulinum), and preserve the meat's characteristic pink color and flavor. While synthetic nitrates and nitrites are widely used in conventional processed meats like bacon and hot dogs, organic food production operates under a different set of rules.
The Role of Synthetic vs. Natural Nitrates
Organic standards, such as those set by the USDA's National Organic Program (NOP), explicitly prohibit the use of synthetic additives, including sodium nitrate and sodium nitrite. This means that fresh, whole organic chicken is naturally free of any added curing agents. The concern arises with processed organic poultry, such as deli meats or sausages, which may require preservatives for safety and shelf life. Instead of synthetic chemicals, organic processors use 'natural' sources of nitrates derived from vegetables.
The 'Uncured' and 'No Nitrates Added' Labels
One of the most confusing aspects for consumers is the labeling of organic and natural processed meats. You might see a package of organic chicken sausages labeled "uncured" or "no nitrates or nitrites added," but with a note stating "except for those naturally occurring in celery powder". This is because celery powder and other vegetable extracts contain high concentrations of natural nitrates. When added to meat with a bacterial starter culture, these natural nitrates convert into nitrites, performing the same curing function as their synthetic counterparts. The body metabolizes these naturally derived nitrates and synthetic ones in the same way, meaning the chemical reaction that can form potentially harmful nitrosamines still occurs, especially when meat is cooked at high temperatures.
Comparison Table: Organic vs. Conventional Chicken Processing
| Feature | Fresh Organic Chicken | Fresh Conventional Chicken | Processed Organic Chicken | Processed Conventional Chicken |
|---|---|---|---|---|
| Synthetic Nitrates Added | No | No | No | Yes |
| Natural Nitrates Used | No | No | Yes (via celery powder, etc.) | Sometimes (in "uncured" products) |
| Source of Nitrates | N/A | N/A | Plant-derived | Synthetic (sodium nitrite/nitrate) and/or natural |
| Antibiotics | Prohibited | Often used | Prohibited | Often used |
| Animal Welfare | Higher standards, outdoor access | Variable, often confined | Higher standards, outdoor access | Variable, often confined |
| Nutrient Profile | Often higher in Omega-3s | Variable | Depends on processing | Depends on processing |
The Broader Context of Nitrate Exposure
It's important to remember that cured meats are not the primary source of dietary nitrates for most people. A large portion of our nitrate intake, up to 80%, comes from vegetables like leafy greens (spinach, lettuce) and root vegetables (beets, carrots). In fact, the natural nitrates found in plants are often consumed alongside antioxidants, which can help prevent the formation of nitrosamines. However, the high heat cooking of processed meats—whether cured with synthetic or naturally derived nitrates—is what creates the most concern.
How to Minimize Nitrates in Your Diet
- Prioritize Freshness: Choose fresh, whole, unprocessed organic chicken over any processed variety, as it will have no added nitrates. Look for fresh chicken breasts, thighs, or a whole roaster to cook at home.
- Read Labels Carefully: For organic deli meat or sausages, check the ingredient list for celery powder, celery juice, or other vegetable extracts high in nitrates. The "uncured" label indicates the use of these natural sources, not the total absence of nitrates.
- Consider Alternatives: Opt for non-meat sources of protein like legumes or fresh fish to significantly reduce dietary nitrates from meat products.
- Focus on Whole Foods: A diet rich in fresh fruits and vegetables provides healthy nutrients and antioxidants that counteract the potential negative effects of nitrates.
Conclusion
In conclusion, does organic chicken have nitrates? The answer depends on whether the chicken is fresh or processed. Fresh, certified organic chicken is guaranteed to have no added synthetic or natural nitrates. However, processed organic chicken products, despite being labeled "uncured" or "no nitrates added," contain naturally derived nitrates from sources like celery powder. From a physiological standpoint, the body processes nitrates from natural and synthetic sources similarly. For consumers concerned about nitrates, the best approach is to choose fresh, whole organic poultry and carefully read the labels of any processed meat products to understand exactly what ingredients have been used.

Frequently Asked Questions
Q: Is organic chicken healthier than regular chicken? A: Organic chicken is often considered healthier by consumers because it is raised on organic, non-GMO feed without synthetic pesticides and typically has higher animal welfare standards. Some studies suggest it may also have a more favorable fatty acid profile.
Q: What is the difference between "uncured" and "cured" meat? A: "Cured" meat uses synthetic sodium nitrite or nitrate as a preservative. "Uncured" meat does not use these synthetic chemicals but is instead preserved using natural sources of nitrates like celery powder, which still convert to nitrites during processing.
Q: Are nitrates from vegetables harmful? A: Nitrates found naturally in vegetables are generally not considered harmful and are consumed alongside antioxidants that can mitigate potential risks. The concern lies in the high-heat cooking of processed meats where nitrates and nitrites can react with proteins to form nitrosamines.
Q: Can I tell if a processed meat contains nitrates by the color? A: Not reliably. Both conventional (synthetic nitrate) and organic (natural nitrate) processed meats can achieve the pink, cured color through the action of nitrites, regardless of their source.
Q: Why do some processed organic meats require preservatives? A: Preservatives, whether synthetic or natural, are necessary for processed meats to inhibit bacterial growth, especially spoilage bacteria and dangerous pathogens, ensuring food safety and extending shelf life.
Q: How do natural nitrates like celery powder work? A: Natural nitrates from sources like celery powder are added to processed meats, where bacteria in a starter culture convert the nitrates into nitrites. The nitrites then perform the curing functions of preservation and color development.
Q: Does eating organic chicken help prevent cancer? A: There is no definitive evidence to state that organic chicken, in and of itself, prevents cancer. A diet focused on fresh, whole foods, regardless of organic status, is widely recommended for cancer prevention. The primary risk associated with nitrates comes from the consumption of processed meats, not fresh chicken.
