We all know that milk goes bad if not refrigerated, but why doesn’t it go bad inside the cow?
<|assistant|>
Milk is an incredibly perishable substance and without refrigeration the milk would quickly go bad, just as milk that has been spilt does. Cows produce milk which contains anti-microbial elements, proteins and enzymes which work together to protect the milk and keep it from going bad. In addition, the acidity of the cow's udders helps to keep the milk from being a hospitable environment for bacterial growth. Furthermore, the enzyme "lactoperoxidase" found in cow's milk catalyzes a reaction with oxygen that slows down bacterial growth. Therefore, even though milk is perishable, the elements found in the milk and in the cow's environment, work together to help protect it and keep it from going bad.
