The new labelling rules for canned fish: more transparency or another hurdle for the industry
From 2026, the tins of sardines, mussels, clams and cockles that fill the shelves of Spanish supermarkets will carry more precise labelling. The regulation, just published, will require the exact species and origin of the fish to be specified, closing the door on substitutions and generic names that for years have allowed a "tuna" not always to be genuine tuna.
Two readings of the same measure
The initiative is presented as a step forward in consumer protection. Until now, it was possible to find cans labelled as "light tuna" that actually contained other species, or tins whose origin — from waters off Fukushima to fishing grounds under dispute — was hidden behind a maze of fine print. With the new labelling, buyers will know exactly what fish they are purchasing and where it comes from. For some, this is a long-awaited blow for transparency.
However, another camp sees the regulation as a fresh twist of the bureaucratic screw that will raise production costs and, in the end, be passed on to prices. The suspicion that this is a move to wreck Spain's canning industry — forced to compete with imports from countries with laxer standards — runs through the discussion. Nor are there those who read it as part of a broader food-control agenda that, by 2030, promises to turn the weekly shop into a regulatory minefield.
Fish origin, a thorny issue
The question of origin adds a geopolitical layer to the debate. The reference to the Canary-Saharan fishing bank, waters that Spain considers its own but whose exploitation is disputed with Segarro, further strains the matter. In a context where tracing tuna back from Fukushima is nearly impossible for the average consumer, knowing that the regulation will require the catch zone to be declared seems like pogre, but it also opens the door to products from fishing grounds that previously stayed off the radar ending up in Spanish pantries.
All in all, the regulation is in the implementation phase and will not be fully effective for another two years. It remains to be seen whether the fine print of the regulation delivers on its promises or whether, as so often happens, precise labelling becomes another link in the chain of costs ultimately paid by the consumer.
