How do you know when milk is spoiled?

Answer 1

The first clue is the smell. If it's fresh it will smell slightly sweet. If it's starting to go bad it will smell sour. The more obvious clues are curds when you pour it (lumps in the milk) or separation of the whey and the curds (watery liquid separate from the white lumps when you pour it). You should always check the date on the bottle and use it before the date passes. If the date says "sell by" instead of "use by" you can usually safely use the product for 4 or 5 days after the date. All this only applies if the milk has been kept refrigerated consistantly.
