|---|---|
| Publication | 31 March 2026 |
| Entry into force | 27 March 2026 |
| Affected parties | Importers, manufacturers and distributors of food and feed containing maize MON 87419 |

| Category | European Regulation |
| GMO affected | Genetically modified maize MON 87419 |
Any company in the agri-food sector that has transgenic maize MON 87419 in its supply chain must act now. Implementing Decision (EU) 2026/739, adopted on 27 March 2026 and published on 31 March, eliminates the only legal framework that covered the marketing of this GMO in Europe: Decision 2023/2134, which is formally repealed.
This is not a partial restriction or a labelling change. The revocation is total: no product that contains, consists of or is produced from MON 87419 may remain on the European market.
What does this regulation establish?
Decision 2026/739 formally revokes the authorisation granted in 2023 for genetically modified maize MON 87419. The regulation affects three categories of products:
- Products that contain maize MON 87419
- Products that consist of maize MON 87419
- Products produced from maize MON 87419
This triple category covers both grain in its natural state and processed derivatives, which significantly broadens the scope of the withdrawal. It affects both the food for human consumption sector and the animal feed sector.
| Aspect | Decision 2023/2134 (repealed) | Decision 2026/739 (in force) |
|---|---|---|
| Authorisation status | Valid authorisation to market MON 87419 | Authorisation revoked |
| Permitted products | Food and feed with MON 87419 authorised | Marketing in the EU prohibited |
| Legal framework | Decision 2023/2134 as legal basis | Decision 2023/2134 repealed with no replacement |
Economic and operational impact
The impact is not only regulatory: it has direct consequences on operations, inventories and contracts. Affected companies must bear real costs on several fronts:
- Withdrawal of products from the market: logistical costs of collection, temporary storage and destruction or return of goods.
- Supply chain review: supplier audits to verify the absence of MON 87419 in raw materials, ingredients and compound feed.
- Product reformulation: if any product uses MON 87419 as an ingredient, it must be replaced by a non-transgenic or authorised variety.
- Risk of administrative penalties: the competent authorities of each Member State may impose penalties and order forced withdrawal if non-compliance is detected.
The cost of inaction far exceeds the cost of adapting. A forced withdrawal ordered by the competent authority implies loss of control over the process, public exposure and potential cumulative penalties.
Who is affected?
- Importers of maize or maize derivatives from countries where MON 87419 is authorised (such as the USA or Brazil)
- Food manufacturers that use maize or maize starch as an ingredient and have not verified the variety used
- Compound feed manufacturers that include maize in their formulation
- Wholesale and retail distributors that have products containing MON 87419 in stock
- Agri-food chain operators acting as intermediaries between foreign producers and the European market
Practical example
A Spanish compound feed manufacturer for livestock imports bulk maize from Argentina. In its latest shipment, the maize acquired corresponds to the MON 87419 variety, which until March 2026 was authorised in the EU under Decision 2023/2134.
From 27 March 2026, that shipment can no longer be marketed or incorporated into any feed intended for the European market. The company must:
- Halt the use of that shipment in its production line.
- Check whether there are batches of finished feed that already incorporate that maize and, if so, withdraw them from the market.
- Contact its supplier to renegotiate or return the shipment.
- Document all actions in anticipation of a possible inspection by the competent Spanish authority.
If the company fails to act and the competent authority detects non-compliance, it may order the forced withdrawal of the products and impose administrative penalties.
What should companies do now?
- Audit the supply chain: identify whether any raw material, ingredient or finished product contains, consists of or is produced from maize MON 87419.
- Halt the marketing of any affected product with immediate effect, given that the regulation entered into force on 27 March 2026.
- Withdraw from the market any products already in distribution or at points of sale, coordinating reverse logistics with distributors and customers.
- Replace the supply: contact suppliers to ensure that new maize shipments do not correspond to the MON 87419 variety.
- Document all actions taken (audits, withdrawals, communications with suppliers) to demonstrate due diligence in the event of a possible inspection by the competent authority.
- Review contracts with international suppliers to include clauses guaranteeing the absence of GMOs not authorised in the EU.
