Walk through almost any grocery store and you'll find foods made from genetically engineered crops everywhere.
They're in the chips stacked at the end of the aisle. The cooking oil in your pantry. The salad dressing in your refrigerator and the cereal boxes many families buy every week. More than 90% of the corn, soybeans, and cotton grown in the United States comes from genetically engineered varieties, making those crops a routine part of the American food supply.
Most shoppers probably assume they would know if those ingredients were in the products they buy.
No label, no GMO.
That seems reasonable. It also turns out not to be true.
In October 2025, a federal appeals court ruled that the USDA got part of its bioengineered food labeling rules wrong. The court found the agency made a legal error by exempting highly refined foods from disclosure, and it said the rules allowing disclosure by QR code or text message alone should be struck down.
The case highlights something many shoppers may not realize: some foods made from genetically engineered crops have not been required to carry a bioengineered disclosure on the package.
A Label Hidden in Plain Sight
The National Bioengineered Food Disclosure Standard gives companies several ways to disclose foods that meet the federal definition of bioengineered.
They can print plain text, use the USDA's green bioengineered symbol, provide a text-message option, or use an electronic link such as a QR code.
Once scanned, the bioengineered disclosure is supposed to appear on the first screen. But the wording next to the code does not necessarily tell shoppers that the information concerns bioengineered food. So a consumer may have to pull out a phone, scan the code, and follow the link to learn why it is there.
The information exists. It just requires another step to reach it.
And that matters because consumers do not all approach genetically engineered foods the same way. Some prefer to avoid them, while others are comfortable eating them. Questions about their safety remain part of the broader debate.
But whether someone chooses to eat genetically engineered food is one question. Whether that person can easily identify it is another.
The Larger Issue: Highly Refined Ingredients
Another part of the USDA standard centers on highly refined ingredients — and what happens after a genetically engineered crop is processed.
Corn oil is a good example. It may begin with genetically engineered corn, but refining can remove the modified genetic material until it is no longer detectable. At that point, under the USDA’s rules, the finished product may not need a bioengineered disclosure.
A natural-foods retailer and several advocacy groups challenged that approach.
Consumer groups argued that detectability and origin are not the same thing. A bottle of oil may no longer contain detectable modified DNA, but it can still come from a genetically engineered crop. In October 2025, the Ninth U.S. Circuit Court of Appeals agreed, holding that USDA committed legal error when it treated "undetectable" as if it meant "not there."
That is how a product can end up on the shelf without the bioengineered disclosure a shopper might expect to see.
Safety and Transparency Are Different Questions
This is where the discussion around genetically engineered food can get confusing. Questions about safety are one thing. Questions about transparency are another. USDA itself notes that a bioengineered disclosure is not a statement about whether a food is healthier, safer, or more environmentally sound than a non-bioengineered food. In other words, the word "bioengineered" is not a warning label.
That distinction matters because this is not an argument that genetically engineered food is inherently dangerous. That is a separate conversation for another day. The question here is whether consumers have enough information to understand what they are buying and make their own decisions. A label may not answer every question about a product, but it should at least make the basic facts easier to find.
