We all know that milk goes bad if not refrigerated, but why doesn’t it go bad inside the cow?
<|assistant|>
Milk does not typically go bad in cows because its natural temperature is quite cold. Lactating cows keep their milk at a temperature of 37 to 40 °C, which is too warm for most bacteria to grow. This allows the cow’s milk to remain healthy, safe to drink, and nutritious for their calves. Additionally, milk from many animals, such as humans, does not normally go bad when not refrigerated. Instead, it curdles as the proteins coagulate, and the milk takes on a cheesy flavor due to bacterial or enzymatic activity, but does not actually go “bad” as other foods might.
