As a food safety expert, I always emphasize the importance of following food safety guidelines to prevent foodborne illnesses. The "use by" date on milk is there to ensure the product is at its peak quality and safety. After this date, the milk may no longer be safe to consume, especially if it has been improperly stored.

Milk is a perishable product that can spoil quickly due to the growth of harmful bacteria. Even if it looks and smells fine, it can still harbor bacteria that can cause illness. The texture and taste might change as well, indicating spoilage.

If you're considering drinking milk after its "use by" date, it's generally not recommended. However, if you must assess the milk's safety, you should check for signs of spoilage such as an off smell, curdled texture, or any visible mold. If any of these signs are present, discard the milk immediately.

In conclusion, it's best to err on the side of caution and not consume milk after its "use by" date to avoid the risk of foodborne illness.

You could theoretically freeze your milk for up to three months, but it'll turn lumpy and yellow and yucky looking (though it's still safe to drink). The accepted rule of thumb is that if you're properly refrigerating it, your carton of whole milk's expiration date is five days after the "sell-by" date.read more >>
