If you have milk in the fridge, and the sell-by date is today, do you drink it or ditch it?
Here's the deal. The date on your milk, meat, or other perishables was put on there to remind the retailer how long a product should remain on the shelf. It indicates the food's quality, not safety.
Many foods can be eaten at least 2 days, if not more, beyond the date stamped on the package. As long as you've stored it properly, you're good to go.
Of course, use your best judgment. If it looks, smells or tastes funky - throw it out. It's really not worth getting sick over.
