Organic vs natural vs non-GMO: what each word promises

Organic is a production standard with federal rules behind it. USDA says organic products must be overseen by a certifying agent authorized by the National Organic Program, produced without excluded or prohibited methods such as genetic engineering, ionizing radiation or sewage sludge, and produced using allowed substances.

It also comes with label rules. A product called "organic" must contain at least 95 percent organic ingredients, and one labeled "made with organic" at least 70 percent. Those tiers are explained in our guide to reading a USDA Organic label, and the seal itself on the USDA Organic label page.

Neither of the other two words covers that much ground. Natural, as the FDA uses it, is about what was added to a food. Non-GMO is about one kind of ingredient. Organic is the only one of the three that sets rules for the farm.

Very little that you can check. The FDA says it has not engaged in rulemaking to establish a formal definition for the term natural. What it has is a longstanding policy: it has considered natural to mean that nothing artificial or synthetic, including all color additives regardless of source, has been included in or added to a food that would not normally be expected to be in that food.

The FDA is direct about what that policy leaves out. It was not intended to address food production methods, such as the use of pesticides. It did not explicitly address food processing or manufacturing methods. And the agency did not consider whether natural should describe any nutritional or other health benefit.

The FDA asked the public for comments on the use of the term, and that comment period closed in May 2016. The agency's page on the subject, which we read in October 2026, still describes the same policy and no formal definition.

Meat and poultry are regulated by a different agency, the USDA Food Safety and Inspection Service, and it does have a definition. A natural meat or poultry product contains no artificial ingredient or added color and is only minimally processed, meaning it was processed in a way that does not fundamentally alter the product. The label must include a statement explaining the term, such as "no artificial ingredients; minimally processed."

Notice what is missing from that definition: anything about how the animal was raised, what it was fed or whether it received antibiotics. Those are covered by the organic rules, which is why the picks on our organic meat page are chosen by the seal and not by the word natural.

The butterfly seal belongs to the Non-GMO Project, a private organization, not a government agency. The Project says its Verified mark appears on products that have been evaluated by third-party technical administrators to confirm they meet the Non-GMO Project Standard. The Standard is revised periodically, and the Project states that Version 17 was published on October 1, 2026.

The method is traceability plus testing of ingredients. The Project says its Standard requires testing of individual ingredients or precursors, not finished products, and that ongoing testing is required for all major ingredients derived from high-risk crops. Verified products are reviewed annually to renew the verification.

The Project is also clear about a limit. In its own words, the butterfly label is not a GMO-free claim, because "GMO free" claims are not legally or scientifically defensible given the limits of testing and the risk of contamination. The seal means the product complies with a standard for avoiding GMOs.

That is the whole scope. The butterfly certifies GMO avoidance. It is not a claim about pesticides, additives or how animals were raised. Our Non-GMO Project Verified label page goes through the standard in more detail.

Organic rules prohibit genetic engineering as a method. A certified organic farmer may not plant genetically engineered seed, and an organic product may not use ingredients produced that way. In that sense organic includes non-GMO.

The two standards check it differently, though. The Non-GMO Project points out that the USDA National Organic Program does not require testing for GMOs, while its own Standard does require testing of major high-risk ingredients. That is the Project describing its own advantage, so read it as one standard owner's view, but the underlying difference is real: organic is a rule about practices, and the butterfly adds a testing requirement for certain ingredients.

This is why some products carry both seals, including staples on our organic grains, rice and pasta page. It does not work the other way around. The butterfly sets no organic farming rules, so a non-GMO product is not required to be grown organically.

This is a fourth term, and it works in the opposite direction. The National Bioengineered Food Disclosure Standard, announced by USDA in December 2018, requires food manufacturers, importers and certain retailers to disclose foods that are or may be bioengineered. It is a required notice that something is present, not a voluntary claim that something is absent.

USDA says the Standard defines bioengineered foods as those that contain detectable genetic material that has been modified through certain lab techniques and cannot be created through conventional breeding or found in nature. Disclosure can be made with text, a symbol, an electronic or digital link, or a text message option.

The word "detectable" matters. The disclosure rule is written around what can be detected in the food, and it is not a verification program, so the absence of a bioengineered disclosure is not the same as a non-GMO verification. If avoiding genetically engineered crops is your goal for something like organic cooking oils, the organic seal or the butterfly tells you more than a missing disclosure does.
