Dairy plants are facilities where milk and other dairy products are processed and manufactured. They receive raw milk from farms and transform it into various products such as cheese, yogurt, and butter. The process involves pasteurization, which kills harmful bacteria, and other methods to ensure the products are safe for consumption. These plants play a crucial role in the dairy industry, supporting local farmers and providing a steady supply of dairy products to consumers. They often adhere to strict health and safety regulations to maintain quality and hygiene, ensuring that products meet the standards set by organizations like the Food and Drug Administration (FDA).
