OCU names the worst canned tuna brands sold in Spanish supermarkets
If you regularly reach for a tin of tuna when you need a quick lunch, you probably do not spend […]
A recent study by the OCU (Spanish Consumers' Union) has revealed significant differences in the quality of canned tuna sold in Spanish supermarkets. Researchers examined 32 tins of light tuna in oil, assessing various factors such as tuna species, oil, freshness, salt content, labelling, proportion of fish, physical defects, and professional tasting results. The study found that some brands scored significantly lower than others, with the lowest-scoring option receiving just 64 points out of 100.
Consolas Ortiz AOVE Eco received the lowest score due to its high salt content and subpar labelling, although no significant defects were found during tasting. Carrefour's sunflower oil pack scored 65 points, but its competitive price did not reflect quality matching better-performing products. Cabo de Peñas Aceite Eco scored 67 points, with high salt content, acceptable labelling, and high price affecting its rating.
Despite the varying scores, the study found no safety concerns, with all products containing authorised tuna species, matching oil, low histamine levels, and mercury concentrations well below permitted limits. Surprisingly, spending more did not guarantee better tuna, as two supermarket own-brand products—Sal de Plata from Aldi and Hacendado from Mercadona—offered excellent quality and value for less than €15 per kilogram.
The findings suggest that shoppers should pay attention to salt content, tuna proportion, and labelling when choosing tuna cans.
