Recently milk was bought last Thursday with an expiration date of the 19th. Even after a few days bought I noticed the milk was tasting rather awful. I decided to leave the milk back in the fridge until my father decided to pour it on some cereal. Then my father asked me the same question, I just recently bought the milk and it goes spoiled this quickly.
If you thought you were crazy, you are most likely telling the truth about your spoiled milk story.
The Consumerist has a feature called Is Your Milk going Sour Faster? and explains the mystery of the rapidly spoiled milk. Many people are suspecting that its companies skimping on the temperature either in the store or during the transportation of the product. Maybe we need to go back to buying the gallon containers of milk, because the smaller the container the faster the milk becomes sour.
