My ex-wife thought the 'use by' date meant it wasn't any good afterward and she would throw away or pour out anything that met that mark. This was back in the early 80s when the 'use by' and 'best by' thing first started.Except for a few items like baby formula, I don't find any evidence of a general FDA or USDA requirement for food product dating, whether an expiration or "use by" date. But most food processors put one or the other dates on their products as a guide to shoppers. Especially the "use by" dates, because they want to avoid complaints about products that have lost flavor or aesthetic appeal as they aged. And of course it sells more product too.
The percentage of people who think the use-by date means they should throw the product away makes me shake my head in wonder.
The first time was a half gallon of milk from a 1 gallon jug. She was pouring it down the sink and I asked if it had gone bad and she said, yes, the 'use by' date was yesterday. I asked if she had smelled it and she said she didn't have to because the 'use by' date meant it was no good anymore.
