Swiss Court Bans 'Milk' Label for Plant-Based Drinks in Landmark Ruling

Switzerland's highest court has ruled that only dairy products from animal udders can legally be called 'milk'. The decision, announced on 27 March 2026, blocks plant-based brands from using the term—even in negated forms like 'not milk'. The case centred on Danone's Alpro oat drink, whose playful packaging sparked a legal battle over consumer clarity and food labelling rules. The dispute began when the Zurich Cantonal Laboratory flagged the Alpro oat drink's design as misleading. Its packaging featured the phrase 'SHHH.... THIS IS NOT MILK', with the 'i' in 'Milk' replaced by a milky droplet. The Zurich Administrative Court agreed, ruling that the overall look could trick shoppers into thinking it was cow's milk.

The Swiss Federal Supreme Court upheld this stance in a 4-1 vote. Judges sided with the Swiss Food Safety and Veterinary Office (FSVO), which argued that even negative claims like 'I am not milk' were deceptive. This aligns with a 2025 ruling that banned the term 'Planted Chicken' for similar reasons.

The Swiss Protein Association (SPA) had pushed for more flexible labelling, suggesting phrases like 'This is not milk' could help consumers compare products. However, the Swiss Consumer Protection Foundation (SKS) countered that defining a product by what it isn't makes little sense. The court's strict interpretation now prohibits any reference to 'milk'—positive or negative—on plant-based drinks.

Danone's Alpro oat drink remains on shelves at major retailers like Migros and Coop. But the company must now rethink its branding to comply with the ruling, which goes further than the EU's 2017 ban on dairy terms for plant products. The ruling sets a clear boundary for Swiss food labels: 'milk' is reserved for animal-derived dairy only. Plant-based brands must avoid the term entirely, even in negated or playful forms. With the court dismissing Danone's appeal, the decision reinforces Switzerland's stricter stance compared to EU regulations.
