When you check out the milk in the fridge and see that it is just a day past the expiration date, do you pitch it right away or keep it around? If it looks and smells fine, it is perfectly safe, right?
Expiration and/or sell by dates are listed on the milk container. It is important to identify which is listed on the milk you typically by. If the expiration date is listed, and you see that your milk is still in the fridge past this date, the milk might be fine, but there is no way to be sure. A food or beverage may contain harmful bacteria that can cause foodborne illness, even if it doesn't look or smell rancid.
How can you help deal with this issue? If you have excess milk approaching the expiration date, freeze some in single serving containers that you can then use as needed.
