Ignore The Sell By Date — According to this Mother Jones article, it's not for you: it's "meant for store stockers to keep track of product rotation. It offers little indication of when the milk may actually sour." The story goes on to connect this to a larger problem, that of food waste. 1/3rd of the global food supply is wasted and "here in America, we're even worse: Roughly 40 percent of our food goes uneaten, amounting to an economic loss of $165 billion a year." So keep using that milk until it really is sour.

    That’s great…I was just thinking about this and just kept smelling the milk. My wife bought it and it was a pricey grass fed organic milk, so I wasn’t about to pour it down the drain. All worked out. Thanks for backing up my natural intuition :)

    Expiration dates are for the weak.

    Well it’s right there in the name “sell by date”… that’s just when the stores are supposed to stop selling it, not that it turns to toxic sludge at the stroke of midnight. My mother’s rule of thumb was that you had roughly a week after the date for milk (checking by smell) and the internet taught me you can check eggs in a bowl of water (if it floats throw it away).

    milk (or any other food!) can’t read a calendar. this is a conversation I have often with my family

    I’m not sure how this applies in Uk where I currently live, as being originally from Sweden where the milk doesn’t sour for at least 5 days after the best before date, I intend to keep the milk past it’s date here too and it just goes so so bad like a day after. Same with their breads, the begin to mold even before the best before date has been reached. In fact in UK it seems it’s a common practice to freeze milk and bread. If I did this in Sweden my family and friends would kick me out of their kitchens.

    I think only raw milk sours, pasturized just spoils and ultra pasturized is sold on the shelf unrefridgerated and is only sold in the dairy case to make u think nothing us wrong with it.

    Hey, use it even after it sours as “buttermilk” for baking!
