chosen.content: The reason milk does not go bad inside a cow is because of anaerobic fermentation. During this process, the milk is kept at a certain temperature which prevents aerobic bacteria from forming which causes spoilage. Anaerobic bacteria, which are also found in the animal's gut, produce lactic acid, which preserves the milk. The presence of these bacteria is what gives raw, unpasteurized milk its distinct taste. Pasteurization, which involves heating the milk to a high temperature, kills the bacteria and prevents spoilage. This process also reduces harmful bacteria present in unpasteurized milk, making it safer for consumption.

rejected.content: Cow's milk does not go bad due to the presence of antibodies which fight off bacteria and keep it fresh for the calf's consumption. Milk contains numerous beneficial bacteria that help to keep it from spoiling, and its heat stable protein constituents prevent it from spoiling at warm temperatures. Additionally, milk has a natural coagulating agent (clotting enzyme), called a protease, which aids in the curdling of milk and prevents further growth of harmful bacteria. These factors working together allow cows’ milk to keep fresh and be safely consumed by calves.
