You can buy foods even after the sell-by date , But Before buying a food we need to check all dates yes? and How many days after sell by date is really good? So What’s the difference between Best-By, Use-By, and Sell-By Dates? Stop throwing away perfectly good food! Turns out, you’ve been throwing away perfectly good food.
I used to take expiration dates very seriously. I froze my ground beef before the “Use By” date and if my milk’s “Best If Used By” date was yesterday, I’d toss it. The boxed stuffing mix that expired last month? In the garbage. But after researching the different types of “expiration” labels, I learned that food actually lasts longer than I thought. (But these foods last forever.)

According to the United States Department of Agriculture, food expiration dates refer to food quality, not food safety. Federal regulations do not require that expiration dates be put on meat, poultry, eggs, dairy, cans and boxed foods (baby formula is the only product that requires an expiration date). They are added as a helpful guide to consumers and retailers. Here are the three most common labels:

Best if Used By – This date suggests when a product will be at peak quality. It will still be safe to consume after that date, but the flavor and texture quality will start to go down.
Use By – This date is usually found on more perishable items, like  meat. It’s still okay to consume the product for a short period after the date, but don’t wait too long.
Sell By – This date tells retailers when the product should be off the shelves. Sales are one way grocery stores try to get older inventory into consumers’ carts, and it’s usually pretty effective.

“Use by” dates are a great guide for people like you and me, but it comes at a price. A USDA report states that Americans waste about 30% of food every year. Part of that is because we follow expiration dates too closely and end up throwing out perfectly good food. It’s such a shame. Luckily, we can change. If You See a Best By Date This Is What it Really Means.. Thanks to who shared this first time with us.
