At the coffeeshop the other day, the two people at the next table got to talking about "best before" dates and food safety. I, of course, pretended I wasn't listening to them as I did stuff on my computer, while listening to the interesting bits of the conversation, which was essentially all of it.
One point that stuck out was along the lines of "just because it says 'best before' doesn't mean it's 'worst after'". In other words, food isn't necessarily bad past the expiry date, just not at its best. Yogourt, for example, can last for months.
The man went on to talk about how eating food after the best before date is about making an informed decision. Unless there's a flaw in the manufacturing process, he posited, anything you can get from food (aside from meat) that isn't obviously spoiled isn't going to be very dangerous. Or as he put it, "at my age, I can afford to spend an extra 25 minutes on the toilet if I end up eating something that's a little off." I grinned behind my hand, on which my chin was resting.
The conversation continued to spiral downhill from there, still with me pretending that I didn't have an ear on them. Eventually the woman leaned over to me and said "you're going to have quite the stories to tell your friends about what you overheard today, aren't you?"
I did not miss a beat. I replied drily, "oh, I've got a laptop. I can sit on the toilet all day if I have to!"
A few minutes later, she stopped laughing.
