A food enzyme derived from a genetically modified strain of Aspergillus just passed EFSA's safety review. Somewhere between the press release and the production line, Irish food businesses started asking the wrong question.
The question most are asking: do we need to put "GMO" on the label?
The question they should be asking: do we need to label the enzyme at all?
What EFSA Actually Approved
EFSA's Panel on Food Contact Materials, Enzymes and Processing Aids assessed a phospholipase A1 enzyme produced using a GM strain of Aspergillus oryzae. The GM organism is the production host, not the final product. The enzyme itself is extracted, purified, and added to food during processing.
EFSA found no safety concerns. That matters. It is a rigorous review covering identity, characterisation, toxicology, and exposure estimates. EFSA does not rubber-stamp these applications.
What EFSA does not decide is labelling. That is a separate legal question, and this is where businesses are getting tangled.
The Processing Aid Exemption: Why Most Enzymes Stay Off the Label
Under EU food law, specifically Regulation (EC) No 1333/2008 and Regulation (EC) No 1332/2008, food enzymes used exclusively as processing aids do not need to be declared in the ingredient list. A processing aid is a substance used during manufacturing that has no technological function in the final food.
Lipases and phospholipases used in baking, dairy production, and oil processing almost always qualify. They break down fats during processing. By the time the product reaches the consumer, the enzyme is either denatured, removed, or present at levels too low to have any effect. It did its job. It left the building.
That means no ingredient declaration. No "contains food enzyme." No mention at all.
This is not a loophole. It is deliberate policy, built into the architecture of EU food law from the start.
Where GMO Labelling Rules Fit In
Regulation (EC) No 1829/2003 requires GMO labelling when a final food product contains, consists of, or is produced from a GMO. The key phrase is "produced from."
Interpretations of "produced from" have been contested in European courts. The consistent position is that if the GM organism was used in production but is not present in the final product, and no DNA or protein derived from the GM organism can be detected in the final food, the GMO labelling obligation does not apply.
Enzymes produced using GM host organisms like Aspergillus are a classic example. The enzyme protein itself is not a GMO. It was made by one, but it is a purified protein. If that protein is then used as a processing aid and leaves no detectable trace in the final product, the GMO labelling trigger is not met.
This covers the vast majority of food enzyme applications in commercial use across Ireland and the EU right now.
The Confusion Is Real, and Understandable
Consumers hear "genetically modified" and reasonably assume transparency should follow. That instinct is not wrong. The issue is that EU food law drew a line between GMO-derived products that end up in food versus GM organisms used as production tools that do not.
Whether that line is drawn in the right place is a legitimate debate. Ireland's Food Safety Authority, the FSAI, operates within the EU framework on this. They do not have discretion to impose stricter GMO labelling than the regulation provides for, except where national rules explicitly permit it, which they do not here.
Food business operators who want to go beyond the legal minimum can. Voluntary labelling like "made using enzymes derived from GM sources" is permitted, provided it is not misleading. Some operators in premium and organic-adjacent markets are starting to include this. It is a commercial decision, not a legal one.
What Food Businesses Actually Need to Do
Check how the enzyme is used. If it functions as a processing aid with no technological effect in the final product, standard labelling rules apply. No declaration needed.
Check your supplier documentation. Your enzyme supplier should provide a technical dossier confirming the production organism, purification process, and whether any GM material is detectable in the finished enzyme preparation. Keep this on file. If an inspector or buyer asks, you need to show your reasoning.
Check your finished product specification. If the enzyme has a technological function in the final food, say it acts as a preservative or texture modifier in the finished product, the processing aid exemption does not apply. It becomes a food additive and must be declared.
Review your allergen and novel food position separately. EFSA approval under the food enzymes framework does not automatically cover all regulatory bases. If your product goes into the UK market post-Brexit, you are dealing with the Food Standards Agency's food regulation framework as a parallel system, and the positions do not always align neatly.
Do not guess. The FSAI has a business helpline. Use it. The cost of a brief call is considerably lower than the cost of a mislabelled product.
The Transparency Problem Nobody Wants to Name
EU food law was built to protect consumers from genuine risks, while allowing an efficient food system to function. That balance made sense when the choices were simple. Now consumers want to know more, not just whether something is safe, but how it was made, what systems were used, and whether the values of the producer match their own.
The regulation has not caught up with that expectation. EFSA's scientific process is robust. The labelling framework is legally coherent. But the gap between what the law requires and what consumers think they are being told is growing wider.
Food businesses that get ahead of that gap, with clear supplier transparency, documented decision-making, and honest voluntary disclosures where appropriate, will be better placed when the rules inevitably tighten.
The enzyme is safe. The approval was sound. The label probably stays blank, legally speaking. Whether that is the full answer is a different question entirely.
