Milk can often be consumed after its expiration date, generally for up to three days for opened milk and up to seven days for unopened milk. However, the actual shelf life of milk can vary depending on factors such as storage temperature and type of milk.
Here are some general guidelines:
- Unopened milk: Typically lasts up to 7 days past the expiration date.
- Opened milk: Typically lasts up to 3 days past the expiration date.
- Whole milk: Lasts 5-7 days past the expiration date.
- Reduced-fat and skim milk: Lasts 7 days past the expiration date.
- Non-fat and lactose-free milk: Lasts 7-10 days past the expiration date.
It's important to note that these are just general guidelines. The best way to determine if milk is still good is to use the sniff test. If the milk has a sour or off smell, it's best to discard it.
