How do you know if a product has GMO in it?

4 min read

Since January 2022, the U.S. Department of Agriculture (USDA) has required mandatory labeling for certain foods containing genetically modified ingredients. This means that knowing how do you know if a product has GMO in it is now more straightforward for consumers who want to make informed decisions about their food choices.

Quick Summary

This guide provides practical methods for identifying genetically modified organisms (GMOs) in products. It explains how to interpret the Bioengineered (BE) food symbol, understand the significance of organic certification, and decipher PLU codes on fresh produce.

Key Points

  • Check for the Bioengineered (BE) Symbol: The USDA requires a round symbol or text on packaging for products containing detectable genetically modified material.

  • Look for the Non-GMO Project Verified Seal: This voluntary third-party certification with a butterfly logo indicates rigorous testing and avoidance of GMOs.

  • Choose USDA Certified Organic Products: Any product with the USDA Organic seal is, by definition, non-GMO, along with other strict environmental standards.

  • Decipher PLU Codes on Produce: A 5-digit PLU code starting with '9' means organic (and non-GMO), while a code starting with '8' theoretically signifies GMO, though it's rarely used.

  • Be Aware of High-Risk Ingredients: Processed foods containing ingredients like corn, soy, canola oil, and sugar from sugar beets are likely to be genetically modified unless otherwise certified.

  • Consider Refined Ingredients: Be mindful that federal labeling laws have exemptions for highly refined oils and sugars, which may contain GMOs but lack a BE label.

Navigating the grocery store aisles can be confusing, especially with so many labels and certifications claiming to offer transparency about food production. For consumers who want to know how do you know if a product has GMO in it, a few simple steps can help clarify the situation. Understanding the different labeling systems, both mandatory and voluntary, is key to making choices that align with your personal preferences.

Decoding mandatory GMO and Bioengineered (BE) labels

Since early 2022, the U.S. has a mandatory labeling standard for bioengineered foods, which are foods that contain detectable genetic material modified through genetic engineering. This is one of the most reliable ways to identify products with genetically modified ingredients in the U.S.

The official Bioengineered (BE) symbol

Look for a circular green, white, and blue symbol on product packaging. The symbol contains a plant, sun, and stylized text that says "Bioengineered". Some brands may use alternative disclosures, including:

  • Text on packaging: Phrases like "Bioengineered food" or "Contains a bioengineered food ingredient" may be printed near the ingredient list.
  • QR codes: A square QR code can be found on some packages, which you can scan with a smartphone to visit a website with more information.
  • Electronic links: Some brands provide a text message number or website address to provide information upon request.

This mandatory labeling standard is enforced by the USDA. However, it's important to note that the law has some exemptions. For example, animal products may not be labeled as bioengineered even if the animal consumed genetically modified feed. Highly refined ingredients, such as refined oils and sugars, are also exempt if the processing removes all detectable modified genetic material.

Recognizing trusted third-party certifications

Voluntary labels can provide additional assurance and often have stricter standards than the federal mandate. These labels are typically overseen by non-profit organizations or certification bodies.

The Non-GMO Project Verified seal

The most recognizable voluntary label is the Non-GMO Project Verified seal, which features a monarch butterfly. This certification means the product has been evaluated by an independent third party and has met a rigorous standard for GMO avoidance. The Non-GMO Project requires ongoing testing of high-risk ingredients and annual renewal of certification, providing a higher degree of confidence. Some of its key features include:

  • Testing of ingredients: The program tests ingredients derived from high-risk crops like corn, soy, and canola.
  • Animal feed consideration: For animal products like meat, eggs, and dairy, the certification requires proof that the animal feed was non-GMO.
  • Coverage of processed foods: This certification is valuable for processed foods where refined ingredients might be exempt from the federal Bioengineered label.

USDA Organic certification

The USDA Organic seal is also a reliable indicator that a product is non-GMO. The standards for organic certification strictly prohibit the use of genetically modified organisms in any part of the production process. If a product carries the USDA Organic seal, you can be certain that it is also non-GMO. However, a product that is Non-GMO Project Verified is not necessarily organic, as it might have been grown with synthetic pesticides or fertilizers.

Deciphering PLU codes on fresh produce

For fresh fruits and vegetables, the sticker with the Price Look-Up (PLU) code can provide information on how the item was grown. While this method isn't foolproof, it offers a quick check for unpackaged produce.

  • 4-digit code: Indicates the produce was conventionally grown using standard agricultural practices, which may include GMO seeds.
  • 5-digit code starting with an "8": This code theoretically identifies genetically modified produce. However, its use is voluntary and extremely rare in the marketplace.
  • 5-digit code starting with a "9": This identifies certified organic produce, which is non-GMO.

Understanding high-risk ingredients and foods

Some crops are more likely to be genetically modified than others. If you see these ingredients on a label without a Non-GMO or Organic certification, it's safe to assume they may be genetically modified. The most common GMO crops include:

  • Corn
  • Soybeans
  • Canola oil
  • Sugar beets
  • Cottonseed oil
  • Papaya (most Hawaiian papaya is GMO)
  • Zucchini and yellow summer squash (some varieties)
  • Potatoes and apples (certain non-browning varieties)

Navigating the labels: A comparison table

Feature Bioengineered (BE) Label Non-GMO Project Verified USDA Organic Seal
Regulation Type Mandatory for certain products with detectable GM material in the U.S. since 2022. Voluntary, independent, third-party verification. Federally regulated organic standard.
Requirements Disclosure required for foods with detectable levels of modified DNA. Has exemptions for highly refined ingredients. Avoidance of GMOs down to a strict action threshold (0.9% in some cases). Prohibits GMOs entirely. Also forbids synthetic pesticides, fertilizers, and antibiotics.
Certification Cost Cost is for compliance with federal law, built into business operations. Fee-based, varies by product complexity. Fee-based, covers broader organic standards.
Key Identifier Circular BE symbol, text, QR code, or electronic link. Distinctive monarch butterfly logo. Green and white USDA Organic seal.

Conclusion: Empowering your choices at the store

While identifying products with genetically modified ingredients can seem complex, using a combination of methods allows for a comprehensive assessment. The federal Bioengineered label provides a mandatory baseline for disclosure, while the Non-GMO Project Verified and USDA Organic seals offer more stringent third-party verification. By understanding these labels, recognizing high-risk crops, and using tools like PLU codes, consumers can confidently navigate the supermarket and feel empowered by their purchasing decisions. Remember, every label provides a piece of the puzzle, and informed choices are a matter of knowing how to interpret the information available.

Frequently Asked Questions

The terms are used interchangeably, but "bioengineered" is the official term used by the USDA for its mandatory labeling standard. A "bioengineered food" is one that contains detectable genetic material that has been modified through genetic engineering.

No, not all products. Some foods are exempt from the mandatory BE labeling requirement, including certain refined ingredients like oils and sugars where the modified genetic material is no longer detectable after processing.

No. The USDA Organic standards prohibit the use of genetically modified organisms. Any product carrying the USDA Organic seal is considered non-GMO.

Not necessarily. The Non-GMO Project Verified seal focuses exclusively on GMO avoidance. The product may have been grown with synthetic pesticides or fertilizers, which are prohibited in organic production.

On fresh produce, a 5-digit PLU code starting with a '9' indicates it is organic and non-GMO. A conventional product has a 4-digit code. While a code starting with an '8' can indicate GMO, its use is rare.

Common genetically modified crops include corn, soybeans, canola, sugar beets, and Hawaiian papaya. Derivatives from these crops are frequently found in processed foods.

No. In the U.S., the term "natural" is not regulated to mean non-GMO. A product can be labeled "natural" but still contain genetically modified ingredients.
