Why does milk go bad if we are not at home for a couple of days?
I was wondering, why does milk go bad if we are not at home for a couple of days?
Milk goes bad when left out of the refrigerator because the bacteria in the milk multiply rapidly at room temperature. The bacteria convert lactose, a sugar in milk, into lactic acid, which causes the milk to sour and ultimately spoil.
