In Spain there is since 2020 a ban on selling food below cost price. This applies to each link in the production chain to protect producers. The Spanish organization of dairy processors FENIL is now challenging this ban at the Spanish supreme court. FENIL argues that the ban is contrary to the common market organization, which stipulates that all contractual elements are freely negotiable when selling milk. In addition FENIL points to possible damage to dairy farmers as a result of price regulation. If it is no longer possible to sell milk at prices that only cover costs, overproduction could lead to sales problems, according to FENIL. The farmers organization UPA has asked the supreme court to uphold the current ban. Because despite the fact that Spain has to import milk to meet demand, dairy farmers are suffering losses, which has led to the closure of thousands of dairy farms in recent years. Spanish dairy farmers accuse dairies of paying farmers too little for their milk, causing them to work at a loss.
