Spanish Supermarket Giant Fined €30,000 Over Labelling That ‘misled Shoppers’

Spain’s Ministry of Consumer Affairs has fined Mercadona €30,000 after concluding that the labelling and presentation of one of its private-label food products could mislead shoppers about its ingredients. The sanction relates to the supermarket chain’s “tortillas de avena 51%”, an ”oat” wrap-style bread product sold under Mercadona’s Hacendado range.

The investigation began following a complaint filed by FACUA-Consumidores en Acción, which argued that the packaging created confusion about the cereal content of the product. According to Spain’s Ministry of Social Rights, Consumer Affairs and Agenda 2030, the retailer committed three separate breaches of food labelling rules. Authorities issued three fines of €10,000 each covering misleading product presentation, incomplete company information and failures linked to mandatory naming requirements.

Authorities say packaging created confusion

Consumer officials stated that the wording and design of the packaging gave the impression that oat flour was the primary or sole cereal ingredient, despite the inclusion of refined flours. Regulators argued that this could influence purchasing decisions among consumers specifically looking for wholegrain or oat-based alternatives. Under Spanish food regulations, bread and wrap products must clearly identify the cereals used in their preparation. Authorities concluded that the presentation of the product did not provide sufficiently clear information about its true composition.

The ministry also found that the packaging omitted details identifying the company responsible for marketing the product. In the case of supermarket own-brand goods, retailers themselves are legally responsible for ensuring labels comply with consumer protection laws, even when products are manufactured by external suppliers. Officials stated that consumers must be able to understand the nature of a product quickly and accurately without needing to closely analyse ingredient lists or nutritional tables. The investigation concluded that the overall presentation of the wraps could lead shoppers to assume they were buying a product with a greater oat content than was actually the case.

Mercadona rejects the sanction

Mercadona has disputed the ministry’s conclusions and is considering an appeal before the High Court of Justice of Madrid.

The company stated that the product already included the legally required ingredient information and maintained that the labelling complied with applicable regulations. Mercadona also defended the standards used across its private-label range, saying its products are designed to provide customers with clear and accurate information.

Reports indicate that the ministry did not initially identify the supermarket publicly because of restrictions surrounding the publication of sanction procedures before they become fully finalised. However, the case quickly became linked to Mercadona following the original FACUA complaint and later reporting by national news outlets.

The ruling formally closes an investigation carried out by the Directorate-General for Consumer Affairs. Alongside the financial penalty, the ministry has ordered the supermarket to correct the issues identified during the inspection process.

Wider implications for supermarkets

Although €30,000 is a relatively small fine for a retailer of Mercadona’s size, the decision is significant because it reinforces the responsibility supermarkets hold over the marketing and labelling of their own-brand products. The case comes with growing scrutiny across Europe over food packaging and the way products marketed as healthier alternatives are presented to consumers. Terms linked to oats, wholegrains and fibre are increasingly used in supermarket branding because they appeal to shoppers seeking healthier diets and less processed foods.

Consumer organisations have repeatedly argued that some packaging creates misleading impressions even when ingredient lists technically comply with regulations. Regulators across several European countries have stepped up monitoring of claims linked to nutrition, natural ingredients and wholegrain content in recent years. The decision may encourage supermarkets to review the wording, branding and imagery used across private-label packaging. Retailers could also place greater pressure on suppliers to ensure products meet both legal requirements and consumer expectations regarding transparency.

What the ruling means for consumers

For consumers, the ruling highlights the importance of carefully checking ingredient lists rather than relying solely on front-of-pack branding or product names.Spanish authorities concluded that the overall appearance and wording of the packaging could lead the average shopper to believe the wraps contained a higher proportion of oat or wholegrain ingredients than they actually did. Consumer groups say this is particularly important for shoppers making purchasing decisions based on health or dietary concerns.

The case may also lead to clearer food labelling standards in supermarkets if retailers take steps to avoid similar investigations. Greater transparency could help consumers compare products more easily and better understand exactly what they are buying. The ruling comes at a time of increasing public attention on food marketing and nutritional claims across Europe. As regulators continue to examine how products are presented to shoppers, supermarkets may face greater pressure to ensure packaging reflects the true nature and composition of the foods they sell.
