Milk is generally good for about 5 to 7 days after the expiration or "best by" date if it remains unopened and properly refrigerated. Once opened, milk typically lasts about 2 to 3 days past the expiration date
. Key points include:
- Unopened milk: Usually stays fresh for 5–7 days beyond the printed date when stored at the right refrigerator temperature (ideally between 34°F and 38°F)
- Opened milk: Remains good for about 2–3 days after opening past the expiration date, though some sources say up to 4-7 days depending on storage conditions
- Storage tips: Keep milk in the coldest part of the fridge (not the door) to extend freshness. Avoid leaving milk out at room temperature for more than 2 hours
- Signs milk has gone bad: Sour smell, off taste, curdling, or changes in color or texture indicate spoilage and milk should be discarded
- Shelf-stable or ultra-pasteurized milk: Can last significantly longer unopened (up to 30-90 days) but must be refrigerated after opening
In summary, milk can often be safely consumed several days after the expiration date if stored properly, but always check for spoilage signs before use.
