The Source: Food Expiration Dates Getting Reality Check


Today Walmart announced that it was going to require it's suppliers to follow a standardized food "sell by" date guideline. That's because nationally there are no federal labeling standards for food other than baby food. Confusion over when food is spoiled and when it is fine has led to tons of food being wasted every year.

In the U.S. nearly 47 million people live in households that are food insecure. Beyond that, the large piles of food decomposing in our landfills is generating climate-changing methane.

Here is John Oliver's take on that:

Do you follow food "sell-by" dates? Do you throw it out because the date is past though the food appears fine?
