"Sell by" is instead replaced with clearer, more standardized wording. Please at least read the (very short) article before posting.

Did you read what they are replacing it with? I.e., "best if used by" (indicating the time the item is at its best quality), "best if frozen by", and "use by" (indicating when the food is and isn't safe to eat). Because those seem much more clear and useful to me than the useless "sell by" date.

The explanation is in the subtitle. Didn't even have to read the article on this one.
