is there a difference between use by date and expiration date
Sell-By Date: Refers to the last day a retailer can display a product for sale; typically a food is safe to eat for 10 days after the Sell-by Date if refrigerated properly. Use-By Date: Refers to the last day a product will maintain its optimum freshness, flavor, and texture. Beyond this date, the product begins to deteriorate although it is still edible. Expiration Date: Means what it says - if you haven't used a product by this date, toss it. Zuckerbrot pointed out a surprising fact: with the exception of baby food and infant formula, dating is not required by U.S. federal law.
