Lait de foin is an association recognized as a Defending and Managing Organization since 2018, composed solely of producers and not directly involved in milk production or distribution. Its mission is to promote the hay milk sector nationally, distinguishing it from other types of milk. The association provides information and communication about the benefits of hay milk to consumers and manages certification requests from farms. It also conducts independent inspections as part of its role as a defending and managing organization for the traditional hay milk specialty in France.
