A good dairy farm looks after its animals, land and water, producing milk safely under New Zealand food safety rules. If you are visiting a farm, ask first, as working farms have machinery, livestock and biosecurity rules, and follow instructions about gates, dogs and keeping to marked areas. Regulars buy farm products such as milk, cheese or ice cream where sold directly, ask about how animals are kept and check dates and storage, as fresh dairy needs to stay cold. In New Zealand, raw milk sales are tightly regulated, so it is worth asking about the rules. Rural businesses often work by appointment or keep shorter hours, so ringing ahead is wise.
