Fonterra is the world's largest dairy exporter, owned as a co-operative by approximately 10,000 New Zealand dairy farmers. It produces and markets dairy ingredients, consumer brands, and foodservice products globally, with key brands including Anchor, Mainland, Anlene, and Western Star. The company supplies significant dairy products to Australia and owns Australian brands, though it has faced scrutiny over milk pricing practices and the 2013 botulism contamination scare.
