The National Food Chain Safety Office (Nébih) of Hungary regulates the production of food of animal origin for the Hungarian market. It ensures that milk, primarily from cows but also from sheep, goats, and buffalo, meets European Union standards. The agency conducts tests on milk and the animals that produce it twice a month. It also monitors the diet and health of the animals, as the quality of the milk can be affected by what they eat. The milk's color can vary based on the diet, with yellow milk resulting from consumption of green fodder rich in carotene. Nébih's website provides a list of establishments that are subject to a permit and the type of animal milk they can receive.
