5 min read

Over 90% of some key U.S. crops, including corn and soybeans, are now grown using bioengineered seeds. This widespread adoption naturally leads many to question: Are bioengineered food ingredients safe? The answer involves understanding scientific consensus, stringent regulatory processes, and the lingering public concerns surrounding these modern food innovations.

Quick Summary

The safety of bioengineered ingredients is widely affirmed by leading scientific and regulatory bodies, though public opinion remains divided. Regulations and labeling standards aim to ensure food safety and transparency for consumers.

Key Points

Scientific Consensus Confirms Safety: Major scientific bodies like the FDA, WHO, and National Academies of Sciences confirm that currently available bioengineered foods are as safe as their conventional counterparts.
Rigorous Regulatory Oversight: Bioengineered foods undergo extensive pre-market testing and are regulated by multiple government agencies (FDA, USDA, EPA) to ensure they are safe for people, animals, and the environment.
BE Labeling Is Mandatory But Limited: The USDA's disclosure standard requires labels on many bioengineered foods, but excludes highly refined ingredients and products from restaurants or very small manufacturers.
Potential for Environmental and Health Benefits: Bioengineering can offer benefits such as higher yields, improved nutrition, and reduced pesticide use for specific crops, contributing to greater food security.
Public Concern Persists Despite Evidence: Factors like lack of transparency, distrust in biotech companies, and media reporting can fuel public skepticism and misinformation about the long-term safety of bioengineered foods.

Understanding the Terminology: Bioengineered vs. GMO

Before delving into safety, it's crucial to clarify the terms 'bioengineered' and 'genetically modified organism' (GMO). While often used interchangeably by the public, the USDA's National Bioengineered Food Disclosure Standard (NBFDS) uses "bioengineered" (BE) as the official term for labeling purposes. A BE food is defined as one that contains detectable genetic material modified through laboratory techniques that could not be achieved through conventional breeding. Not all GMOs require the BE label; for example, highly refined products like oils and sugars derived from BE crops are often exempt if they do not contain detectable genetic material from the modification.

A Closer Look at the Regulatory Landscape

In the United States, the regulation of bioengineered foods is a collaborative effort involving three federal agencies: the Food and Drug Administration (FDA), the U.S. Department of Agriculture (USDA), and the Environmental Protection Agency (EPA). This multi-agency approach ensures comprehensive oversight from various safety perspectives.

The FDA's Role: The FDA evaluates the safety and nutritional characteristics of foods from new plant varieties, regardless of the method used to produce them. Before a BE food can enter the market, its developer voluntarily consults with the FDA, providing data on potential toxicity, allergenicity, and changes in nutritional content. The FDA has consistently stated that foods from genetically engineered plants are as safe and wholesome as their non-GE counterparts.
The USDA's Role: The USDA's Animal and Plant Health Inspection Service (APHIS) is responsible for ensuring that BE plants are not harmful to other plants. The USDA also manages the National Bioengineered Food Disclosure Standard, which mandates the labeling of most foods containing BE ingredients.
The EPA's Role: The EPA evaluates and regulates pesticides, including those engineered into food crops (called Plant-Incorporated Protectants or PIPs), to ensure they are safe for consumption and the environment.

The Scientific Consensus: A Foundation of Safety

An overwhelming consensus among major scientific and health organizations supports the safety of currently available bioengineered foods. For example, a thorough review by the National Academies of Sciences, Engineering, and Medicine found no evidence that foods from GE crops were any less safe than those from non-GE crops. The World Health Organization (WHO) and Health Canada have also reached similar conclusions, noting that GM products currently on the market have passed safety assessments and are unlikely to present risks to human health.

This consensus is built on decades of research and rigorous testing. In fact, many experts argue that due to the heightened scrutiny, BE foods may be among the most thoroughly tested foods in the supply chain.

The Potential Benefits of Bioengineered Foods

Bioengineered ingredients are not just about cost reduction and efficiency; they offer a range of potential benefits that address significant global challenges.

Increased Crop Yield: Bioengineered crops can be modified to better resist pests, diseases, and harsh weather conditions like drought, leading to more stable and reliable food supplies.
Enhanced Nutrition: Some bioengineered foods, such as Golden Rice, have been developed to enhance nutritional value, providing vital nutrients like Vitamin A in regions with widespread deficiencies.
Reduced Pesticide Use: Insect-resistant crops, like certain varieties of Bt corn and Bt cotton, have led to a significant reduction in the use of chemical pesticides, which benefits environmental sustainability and farmer health.
Lowered Production Costs: Increased efficiency and higher yields can reduce overall production costs, which can translate into lower food prices for consumers.

Consumer Concerns and Remaining Questions

Despite the scientific consensus, public concern persists, often centered on potential long-term health effects that may not have been detected yet. Other issues include potential allergenicity and antibiotic resistance. While regulatory bodies and industry-funded studies have not identified significant issues, some animal studies with methodological limitations have raised concerns about adverse events, necessitating further, high-quality, independent research, particularly long-term human studies. Concerns also exist over the corporate control of seed patents and potential impacts on smaller farmers.

Navigating the Disclosure Standard and Your Choices

Understanding the labeling requirements can help consumers make informed decisions. Since January 1, 2022, manufacturers have been required to disclose BE ingredients on food packages in the U.S..

Key points about the USDA BE Disclosure:

Required Disclosure: Manufacturers can use text (e.g., “Contains a bioengineered food ingredient”) or a specific USDA-created symbol.
Digital or Text Option: A QR code or phone number can also be used to provide disclosure information.
No Identification of Specific Ingredient: The disclosure indicates the presence of a BE ingredient but does not require identifying which one.
Voluntary Disclosure: Ingredients derived from BE crops but with no detectable modified DNA in the final product (like corn oil or sugar) have a voluntary disclosure option.
Exemptions: Food from restaurants, very small manufacturers, and most products where meat, poultry, or eggs are the primary ingredient are exempt.

Comparison: Bioengineered vs. Conventional Food Attributes


Feature	Bioengineered Food	Conventional Food
Regulation	Subject to rigorous, multi-agency regulatory review (FDA, USDA, EPA) before market entry.	Regulated under general food safety laws, but does not undergo the specific, extensive pre-market review required for BE foods.
Safety Consensus	Leading scientific bodies globally consider currently approved BE foods to be as safe as conventional foods.	Considered safe based on a long history of traditional breeding and consumption.
Purpose	Created in a lab to enhance specific traits like pest resistance, nutritional value, or yield.	Developed through traditional selective breeding methods to achieve desirable traits.
Labeling (US)	Mandatory disclosure using text, a symbol, or a digital link (QR code), with some exemptions.	Does not require a bioengineered disclosure label.
Associated Herbicide Use	Often engineered to be tolerant to specific herbicides, potentially leading to increased use of certain chemicals.	Can involve the use of pesticides and herbicides, but without the specific genetic link to herbicide-tolerant traits.

Conclusion

The question of are bioengineered food ingredients safe? has been addressed extensively by the scientific community, with major health and regulatory organizations worldwide finding them to be safe for consumption. However, the conversation is complex, encompassing not only safety but also public trust, environmental impacts, and ethical considerations. Consumers have access to labeling information, though its scope has limitations, and can choose to seek out alternatives like organic foods, which prohibit the use of bioengineered ingredients. Ultimately, making an informed decision requires understanding the science, the regulatory landscape, and the ongoing public debate. For the latest scientific perspectives, consulting reputable organizations like the National Academies of Sciences, Engineering, and Medicine is recommended.

Frequently Asked Questions

Not exactly. The term 'bioengineered food' is the specific, official label mandated by the USDA's disclosure standard. While it refers to certain genetically modified organisms (GMOs), the standard has a narrower definition and includes exemptions, meaning not all foods containing GMOs will carry a 'bioengineered' label.

No. The American Cancer Society and other health bodies have stated there is no evidence that eating genetically engineered foods will change your DNA. The genetic material in food is digested and broken down in the stomach and intestines like all other food components.

While regulatory assessments and decades of research have not shown any long-term health risks from currently available bioengineered foods, some critics argue for more long-term, independent human studies. All approved products are considered safe based on the data available to regulatory bodies.

When developing bioengineered foods, developers are required to test for potential allergens. Regulatory agencies like the FDA have concluded that currently available BE foods are no more likely to cause allergies than their non-BE counterparts.

To avoid bioengineered ingredients, look for the USDA Organic seal, as the organic program prohibits their use. Alternatively, choose products with the 'Non-GMO Project Verified' label, which follows stricter guidelines. You can also focus on whole, unprocessed foods.

Public perception is influenced by various factors beyond scientific data, including media reporting, ethical beliefs about 'tampering with nature,' and distrust in regulatory agencies and biotech companies. Lack of information and confusing terminology can also contribute to negative sentiment.

Yes, one application of bioengineering is to improve the nutritional content of food. For example, 'Golden Rice' was developed to contain higher levels of beta-carotene to combat Vitamin A deficiency.
