Data from DECO (Associação Portuguesa para a Defesa do Consumidor) sent to Lusa show the price of a box of six eggs has risen by about €0.50 since February 2025 and has been broadly stable so far in 2026, ECO and CNN Portugal report. The outlets cite the same overall change but differ on baseline figures reported, so exact past prices vary by source. Shoppers and anyone budgeting household groceries should factor slightly higher basic‑food costs into monthly spending.

Context & Explainers
Deco Proteste is Portugal's largest consumer rights organization, providing independent product testing, legal advice, dispute mediation, and advocacy on behalf of consumers. It is part of the international Euroconsumers group.
Deco publishes comparative tests of products and services (from insurance policies to supermarket prices), lobbies for consumer-friendly legislation, and runs a mediation service that helps resolve disputes between consumers and companies. It also operates helplines during crises — such as severe weather events — to advise on insurance claims, billing disputes, and emergency consumer rights.
Membership is paid, but Deco's public advocacy and media presence make it a significant voice in Portuguese consumer affairs. Its studies and reports are frequently cited in news coverage of cost-of-living, energy prices, and financial products.
