How to tell the difference between GMO and organic

4 min read

According to the USDA, all organic products are, by definition, non-GMO, but the reverse is not true. Consumers can learn how to tell the difference between GMO and organic products by paying close attention to specific labels and codes, which reveal a product's farming and processing methods.

Quick Summary

This guide explains how to identify genetically modified organisms (GMOs) and organic products using clear labeling information. Key identifiers include official certification seals, specific language on packaging, and standardized PLU codes found on fresh produce, empowering shoppers to make informed decisions.

Key Points

  • The USDA Organic Seal: Products with this seal are guaranteed to be produced without genetically modified organisms, synthetic pesticides, or synthetic fertilizers.

  • Not All Non-GMO is Organic: The term 'non-GMO' only means a product does not contain genetically engineered ingredients, but it does not restrict the use of synthetic chemicals like pesticides.

  • Check PLU Codes: Fresh produce with a 5-digit code starting with '9' is organic, while a 4-digit code signifies conventional farming.

  • Recognize Bioengineered Labels: In the U.S., some foods containing genetically modified ingredients are now required to display a 'Bioengineered' or 'BE' label.

  • Organic is a Comprehensive Standard: Organic certification covers the entire farming and processing lifecycle, promoting environmental stewardship and prohibiting GMOs.

Demystifying GMO and Organic Labels

Navigating supermarket aisles can feel like a maze of competing claims and certifications. Understanding the fundamental distinctions between genetically modified organisms (GMOs) and organic products is key for making informed purchasing decisions. While GMOs involve the artificial alteration of an organism's genetic material in a lab, organic farming is a regulated system that prohibits the use of genetic engineering, synthetic pesticides, and synthetic fertilizers.

The USDA Organic Seal: Your Assurance of No-GMOs

For consumers in the United States, the most definitive way to ensure a product is non-GMO is to look for the USDA Organic seal. This certification signifies that the product was grown and processed according to strict federal guidelines, which explicitly prohibit the use of excluded methods, including genetic engineering. The organic standard covers the entire production process, from soil quality and pest control to handling and processing.

Here’s a breakdown of what the seal represents:

  • For crops: No GMO seeds are planted. Prohibited substances like synthetic pesticides and fertilizers are avoided.
  • For livestock: Animals must be fed organic feed and are not given antibiotics or growth hormones.
  • For processed goods: The product must contain at least 95% certified organic ingredients to use the seal.

Decoding Produce (PLU) Codes

For fresh fruits and vegetables, Price Look-Up (PLU) codes offer a quick way to discern farming practices right on the sticker. While not always foolproof or consistently enforced, this system provides valuable clues:

  • 4-digit codes: Conventionally grown produce (e.g., a standard banana coded 4011).
  • 5-digit codes starting with '9': Certified organic produce (e.g., an organic banana coded 94011).
  • 5-digit codes starting with '8': Genetically engineered (GMO) produce (e.g., a GMO banana coded 84011). However, the use of this specific code is rare.

The Rise of Bioengineered (BE) Labeling

As of January 1, 2022, the U.S. National Bioengineered Food Disclosure Standard (NBFDS) mandates disclosure for certain foods containing genetically engineered ingredients. This replaced older, voluntary systems. Look for the 'Bioengineered' symbol or a text disclosure. It's important to note that this labeling does not apply to all products; exemptions exist for refined ingredients with undetectable GMO material, and not all genetically modified items are included.

Understanding the Nuances: Non-GMO vs. Organic

It is a common mistake to think that "non-GMO" and "organic" are the same. A product can be labeled "non-GMO" without being organic. The Non-GMO Project Verified seal is an independent certification that ensures a product was produced without genetic engineering, but it does not prohibit the use of synthetic pesticides, herbicides, or conventional farming methods. Organic certification, on the other hand, is a much more comprehensive standard that includes a no-GMO rule.

Comparison of GMO, Non-GMO, and Organic Labeling

Feature Genetically Modified (GMO/Bioengineered) Non-GMO Organic
USDA Regulation Can be required under NBFDS. Not government-regulated; voluntary standard. Strict USDA certification.
Genetic Engineering Intentionally altered genetic material. No genetic modification; standard breeding. Prohibited.
Synthetic Pesticides/Fertilizers Permitted. Permitted. Prohibited (natural alternatives allowed).
Antibiotics/Growth Hormones Permitted in conventional livestock. Permitted in conventional livestock. Prohibited in livestock.
PLU Code (Produce) May start with '8' (rare). 4-digit code. 5-digit code starting with '9'.

How Intentionality Affects Labeling

An important distinction is that while the presence of a GMO is intentional in a bioengineered product, it can be unintentional in a non-GMO or organic product. For instance, trace amounts of GMOs can inadvertently contaminate organic crops through cross-pollination from a neighboring conventional farm. In these cases, the organic certifying agent will investigate how the contamination occurred and work to prevent it in the future, but it does not automatically revoke the organic certification.

Conclusion: Empowering Your Choices

Ultimately, learning how to tell the difference between GMO and organic requires more than a casual glance at a product. It involves understanding the regulatory frameworks behind the labels. While the presence of the USDA Organic seal offers the most comprehensive assurance of a non-GMO and chemical-free product, other labels like "Non-GMO Project Verified" or the new "Bioengineered" symbol provide specific, but narrower, information. By recognizing these key identifiers—on packaged goods, fresh produce PLU stickers, and ingredient lists—consumers are empowered to make choices that align with their health values, budget, and sustainability concerns. Understanding the distinctions helps move beyond simple buzzwords to a deeper appreciation of our food's journey from farm to table. For more details on the regulations governing organic products, consumers can consult the USDA's National Organic Program website.

Key Takeaways

  • USDA Organic = No GMOs: The presence of the USDA Organic seal is the most definitive guarantee that a product has not been genetically engineered.
  • Not All Non-GMO is Organic: A product can be non-GMO but still be conventionally farmed with synthetic pesticides and other conventional methods.
  • Look for Official Seals: The USDA Organic seal is a federal standard, while the 'Non-GMO Project Verified' butterfly is a third-party, voluntary certification.
  • Produce Code Clues: On fresh produce, a 5-digit PLU code beginning with '9' indicates organic, while a 4-digit code is conventional.
  • Bioengineered Labeling: The term 'Bioengineered' (BE) is now used on some U.S. food labels to indicate genetically engineered ingredients, but there are exemptions.

Frequently Asked Questions

No, non-GMO is not the same as organic. While all certified organic products are non-GMO, a product labeled non-GMO is not necessarily organic. The non-GMO label focuses only on the absence of genetically engineered ingredients, whereas organic certification covers a much broader range of standards, including farming practices, soil quality, and the prohibition of synthetic pesticides.

Look for the USDA Organic seal on packaged goods or a Price Look-Up (PLU) sticker on fresh produce. On the PLU sticker, a five-digit number starting with '9' indicates that the item is certified organic.

No, a non-GMO label does not guarantee that food is chemical-free. Non-GMO products are often grown using conventional farming methods, which can include synthetic pesticides and fertilizers, as long as no genetic engineering was used.

The Bioengineered (BE) food label is part of the U.S. National Bioengineered Food Disclosure Standard. It requires manufacturers to disclose certain foods that contain genetically engineered ingredients using text or a symbol. The standard has some exemptions, notably for refined ingredients where genetic material is no longer detectable.

While the intentional use of GMOs is strictly prohibited in organic products, trace amounts can occur unintentionally, for example, through pollen drift from a neighboring conventional farm. The USDA requires organic certifiers to investigate and ensure prevention measures are in place, but it doesn't automatically mean a violation has occurred.

There is no definitive, universal evidence of a taste difference between GMO and organic foods. Some claim to taste a difference, which may stem from differences in crop varieties, soil health, and farming methods rather than genetic modification itself. Any perceived difference is often subjective.

For meat to be certified organic, animals must be raised according to specific USDA regulations. This includes being fed certified organic feed and not receiving antibiotics or growth hormones. Products with the USDA Organic seal guarantee these standards were met.
