Dive into our in-depth analyses of bioengineered ingredients, genetic modification techniques, and transparent labeling practices to enhance your understanding of food biotechnology and promote informed decision-making in your diet.

1. What Exactly Is Bioengineered Food?

Bioengineered (BE) food, in essence, is the United States government’s chosen term for what are commonly known as Genetically Modified Organisms (GMOs). Under the National Bioengineered Food Disclosure Standard (NBFDS), which took full effect on January 1, 2022, certain foods containing detectable modified genetic material must disclose this fact through labeling. However, this definition and its application are more nuanced than a simple GMO label.

1.1. Delving Deeper into the Definition

The key phrase in the BE food definition is “detectable modified genetic material.” This means that if a food product contains genetic material that has been altered through genetic engineering and this alteration is detectable through testing, it falls under the BE labeling requirements.

1.2. The Implications of “Detectable”

This detectability clause is crucial because it exempts many products derived from GMOs from mandatory labeling. Here’s why:

New Genomic Techniques: Some foods are created using advanced techniques like CRISPR, TALEN, and RNAi. In many cases, the modifications made through these methods are currently undetectable using commercially available tests.
Highly Refined Ingredients: Many processed foods contain highly refined ingredients, such as sugar from GMO sugar beets or oil from GMO canola. The refining process often removes any detectable modified genetic material from the final product.

1.3. Why This Matters

The detectability requirement creates a loophole that allows many foods derived from GMOs to avoid BE labeling. This can be confusing for consumers who are trying to make informed choices about the food they buy.

2. What Foods Require a Bioengineered Label?

The USDA maintains a List of Bioengineered Foods that dictates which foods, in their raw form, are subject to the BE labeling law. As of the latest update, this list includes:

Alfalfa
Arctic Apple
Canola
Corn
Cotton
Bt Eggplant
Papaya (Ringspot virus-resistant)
Pineapple (Pink)
Potato
Salmon (AquAdvantage)
Soybean
Summer Squash
Sugarbeet
Sugarcane

2.1. The “Raw Form” Exception

It’s important to understand that this list applies to these foods in their most basic, unprocessed form. Many products derived from these ingredients may not require a label due to the way the law is structured.

2.2. Exemptions to the Rule

Several categories of products are exempt from the BE labeling law, even if they contain ingredients derived from the USDA’s list:

Animal Feed, Pet Food, and Personal Care Products: These products are entirely exempt from BE labeling requirements.
Meat, Poultry, and Eggs: Foods intended for direct human consumption, such as meat, poultry, and eggs, are also exempt.
Multi-Ingredient Products: Multi-ingredient products where meat, poultry, or eggs are the first ingredient listed are exempt, even if they contain other ingredients with detectable modified genetic material.

2.3. Pork Stew: A Case Study

To illustrate the complexities of the BE labeling law, the USDA provides the example of a can of pork stew. This stew might contain bioengineered ingredients such as sweet corn. Whether or not the stew requires a BE label depends on the order in which the ingredients are listed on the label:

Pork First: If pork is the predominant ingredient listed first, the stew is exempt.
Water/Broth First: If water, broth, or stock is listed first, and pork is second, the stew is still exempt.
Corn First: If the stew contains more corn than pork, the ingredient panel will list corn first, and a BE disclosure is required.

This example highlights a critical flaw in the BE labeling law: Whether a product requires a label depends on the order of ingredients, not necessarily the presence of bioengineered ingredients.

3. What Does a Bioengineered Food Label Look Like?

The USDA allows for several options for how bioengineered food disclosures can appear on packaging:

BE Symbol: The USDA Agricultural Marketing Service has created specific symbols to indicate the presence of bioengineered ingredients.
Text Disclosure: The product package can display a simple text statement, such as “Bioengineered food” or “Contains a bioengineered food ingredient.”
Text Message or Phone Number: Brands may choose to display the phrase “Text [number] for bioengineered food information” or “Call [phone number] for more food information,” which directs consumers to a pre-recorded message.
URL: Small manufacturers are permitted to direct consumers to a website for more information.

3.1. The Problem with Variety

While this variety provides flexibility for brands, it can be confusing for consumers. Consistency in language and labeling is crucial for an effective information campaign.

3.2. Transparency and Intuitiveness

For a label to be truly effective, it must be transparent and easily understood by the average shopper. However, the BE food label doesn’t appear on all products made with GMOs, meaning that the absence of a BE disclosure doesn’t necessarily mean the absence of GMOs.

4. Bioengineered vs. GMO: What’s the Real Difference?

The bioengineered food label was intended to replace earlier GMO labels required by some state authorities. However, the way the term “bioengineered” is applied under the labeling law excludes many products made with GMOs. The key difference lies in the “detectable modified genetic material” requirement.

4.1. The Prevalence of GMOs

GMOs are widely used in the United States, with estimates suggesting they are present in over 70% of conventional processed foods. Organizations like the Non-GMO Project have worked to raise public awareness about GMOs in the food supply.

4.2. Awareness Gap

A 2023 survey indicated that 63% of consumers were familiar with the term “GMO,” while only 36% were familiar with “bioengineering.” This highlights a significant gap in understanding, suggesting that many people are unaware of what a bioengineered food disclosure actually means.

4.3. The Choice of Terminology

The decision to use the term “bioengineered” instead of the more widely recognized “GMO” can be seen as a barrier to transparency in the food system. Clarity and accessibility are essential for effectively communicating information to the public.

5. The “Nature-Identical” Argument

The bioengineered food labeling law requires that the modification made to the GMO cannot be found in nature or achieved through traditional crossbreeding. However, biotechnology companies are increasingly using new genomic techniques to create GMOs that they claim achieve the same results as traditional crossbreeding, only faster.

5.1. Oversimplification of Complex Processes

This claim is reductive and potentially misleading. Gene functions and evolutionary changes are incredibly complex, relying on intricate connections that are not fully understood.

5.2. The Interconnectedness of Nature

To claim that a genetic modification engineered in a lab produces an identical result to an evolutionary process found in nature or traditional breeding is a presumption. It ignores the larger, interconnected picture of how genes and organisms function within their environment.

5.3. Challenging the Premise

As Megan Westgate, Executive Director, aptly puts it: “Whether a GMO is created by combining genes from multiple species or by rearranging or silencing genes within a species, the fundamental premise remains the same — the flawed idea that genes can be reduced to isolated functions, without regard for the complex interplay of the entire genome.”

5.4. Avoiding Disclosure

The biotech industry argues that genetic engineering can create “nature-identical” non-GMO products. This argument supports the development of new GMOs while simultaneously avoiding BE disclosure, leaving consumers in the dark about how their food is produced.

6. What Are the Advantages of Bioengineered Foods?

Bioengineered foods, also known as genetically modified (GM) foods, have become increasingly prevalent in our food supply. While they often spark debate, they also offer several potential advantages.
