On September 16, 2026, a new GMO law took effect in Ukraine, and the 2007 law it replaces lapsed the same day. The change is not cosmetic. One clause in it makes the most common claim on Ukrainian labels illegal.
That claim is “GMO free” on salt, water, oil and anything else that cannot contain a GMO by definition.
What is banned from today
The wording is blunt: the use of a “GMO free” mark is prohibited on products that by their composition cannot contain GMOs and that were made from raw materials which by their composition cannot contain GMOs.
The reasoning is about the shopper. “GMO free” on a bottle of water says nothing about the water, and it says something about the bottles next to it: that those, presumably, are not. The label sells an advantage that does not exist, and the law takes it off the shelf.
The second prohibition covers trade itself. Placing a GMO or GM product on the market is allowed only after state registration of that GMO, and only for the use recorded in the State Register. If the entry is removed from the register, circulation of anything containing it stops.
The 0.9 percent threshold and what it actually covers
A “with GMO” mark is mandatory when any ingredient contains, consists of or is produced from a GMO. There is one exemption: the GMO share does not exceed 0.9 percent and its presence is accidental or technically unavoidable. In that case the business has to show the control authority, on request, what it did to keep the GMO out.
Those two words, accidental or unavoidable, carry the clause. The threshold does not license adding a little GM material and staying quiet. It acknowledges that grain travels in the same wagons and is milled on the same equipment, so a trace is physically inevitable.
The Cabinet of Ministers may set its own thresholds for particular product categories, within a corridor: no lower than 0.1 percent and no higher than 0.9.
| Case | What the label must say |
|---|---|
| An ingredient contains or is produced from a GMO | “with GMO” |
| GMO share up to 0.9%, accidental trace | no marking required |
| Product free of GMOs, but raw material contained them | “GMO free. Produced using raw materials that contained GMOs” |
| Product that cannot contain a GMO at all | “GMO free” is prohibited |
| Meat, milk, eggs from animals fed GM feed | no marking required |
A label that did not exist before
The third row is new. If the finished product contains no GMO but was made using ingredients or components that did, the label has to carry a long formula: “GMO free. Produced using raw materials that contained GMOs”.
It reads awkwardly and it is honest. Until today the same product could sit there marked simply “GMO free”, and the buyer learned nothing about the history of the raw material.
The gap left open on purpose
Labeling requirements do not extend to food of animal origin made from animals fed with GM feed. A chicken raised on transgenic soy carries no mark.
There is a body of work under that exemption rather than a lobbying win. A group at the University of California, Davis pulled together public data on livestock productivity and health from 1983, thirteen years before GM crops appeared, through to 2011. The field data covered more than 100 billion animals after 1996. It showed no unfavourable or perturbed trends in livestock health or productivity.
The same review states the reason the exemption holds up: DNA and protein are normal dietary components and they are digested, so there are no detectable or reliably quantifiable traces of engineered components in milk, meat or eggs after GM feed.
Growing counts as placing on the market
A separate clause treats production, meaning cultivation of genetically modified plants, animals, fungi and micro-organisms, as placing them on the market. The consequence is plain: sowing an unregistered GM line is the same offense as selling it.
Registration is paid for and runs for up to ten years, renewable for up to ten more on an application filed no later than a year before expiry. Whoever places a GMO on the market first draws up a declaration carrying the registration number, and a copy of it travels with the consignment at every stage.
What the science says about the crops themselves
The largest tally comes from the University of Göttingen: a meta-analysis of 147 studies on soybean, corn and cotton. On average, adopting GM technology cut chemical pesticide use by 37 percent, raised yields by 22 percent and raised farmer profits by 68 percent. Gains were larger for insect-resistant crops than for herbicide-tolerant ones, and larger in developing countries. What the herbicides themselves leave behind is covered in our piece on glyphosate in grains and bread.
The authors named the limitation themselves: several of the original studies reported neither sample sizes nor measures of variance. The numbers show a direction, not a guarantee for any given field.
An Italian meta-analysis of field data from 1996 to 2016 adds the part that matters more to a shopper than farm profit. Engineered corn carried lower mycotoxin levels: total concentrations down 28.8 percent, fumonisin down 30.6, trichothecenes down 36.5. The mechanism is mechanical. Insects chew the kernel, mold enters the wound. Fewer wounds, less toxin in the flour.
An honest correction: food DNA does reach the bloodstream
The most common fear is that a foreign gene will lodge in your own genome. A 2019 review, with Michael Antoniou of King’s College London among its authors and a known critic of GM crops, takes that apart piece by piece, and the answer is more interesting than a flat no.
Fragments of food DNA up to a few hundred base pairs survive processing and digestion and are detectable in the gastrointestinal tract. The presence of food-derived DNA, GM food included, in the blood and tissues of humans and animals is described as compellingly supported. Evidence of integration into the consumer’s genome is limited, and the key sentence is this: no evidence that transgenes have a greater propensity for uptake and integration than the plant’s own DNA.
So food DNA does circulate. It applies to all food, and an ordinary tomato behaves no differently from a transgenic one. The authors found no sign of function or expression of plant food DNA after transfer.
What the data does not contain
The question of what actually sits on Ukrainian shelves has no number attached. Published detection rates for the Ukrainian market are not available in the open sources, so any figure here would be invented. The law creates a State Register of GMOs, but on the day it took effect there is nothing in it to quote.
One more question stays open. The law defines a GMO through the transfer of exogenous nucleic acid into the recipient genome, and the phrase “genome editing” does not appear in its text once. The law also excludes methods that change genetic material without recombinant nucleic acid molecules, mutagenesis and protoplast fusion among them. Where crops edited without inserting foreign DNA land is not something the text answers. We have written about both kinds: the gene-edited tomato for vitamin D was made that way, while the purple tomato with snapdragon anthocyanins is a classic GMO with inserted genes.
Key points
- Law 3339-IX took effect on September 16, 2026, and the 2007 biosafety law lapsed the same day.
- “GMO free” on products that cannot contain a GMO is now prohibited.
- “With GMO” is mandatory for any ingredient containing or produced from a GMO. The 0.9 percent threshold applies only to accidental or technically unavoidable traces.
- A new label appears for products made from raw materials that contained GMOs.
- Meat, milk and eggs from animals fed GM feed need no marking, and the exemption rests on field data covering more than 100 billion animals with no perturbed health trends.
- Cultivation counts as placing on the market, so sowing an unregistered line is an offense in itself.
- Across 147 studies: pesticide use down 37 percent, yields up 22, profits up 68. Engineered corn carried 28.8 percent less mycotoxin.
- Food DNA does reach the bloodstream, but transgenes show no advantage over ordinary plant DNA, and no expression was found after transfer.
How the other control systems around food are built is covered in our pieces on antibiotics in meat and milk and on pesticides allowed in organic farming. The wider picture sits in our food safety hub. What the label itself has to carry changed on October 1, 2026, when Ukraine’s wartime labeling waivers were repealed.
