Can frozen milk be drunk after thawing? Frozen milk can be drunk after thawing, but we can't directly thaw the milk, so we can't pick it up and drink it. If we drink it like this, we will have diarrhea. We should thaw the frozen milk and reheat it at a moderate temperature later. After cooking, the medicated milk will be gone, and the milk cooked by bacteria can rest assured. Hehe, it won't have diarrhea after it is finished, so we can drink the frozen milk, but we must drink it.
