No, some things last for a long time, others don’t.

For example:

1. We bought 3 pallets of Almond milk (by mistake! I only wanted 1) at an auction a few years ago. It is all in 1L tetrapaks, and although it went out of date in August 2024, it is still good, and we use it every day.
2. Crisps - We have a pallet of Walkers cheese and onion crisps in “aluminium” (mylar?) bags bought at a similar time. They are still crunchy and taste fine. Some Morrisons own-brand dorito-type corn chips in normal plastic (with see-through section) bags which came in the same package, didn’t fare so well. They lasted less than a year after their BBE date.
3. Organic Seaweed sheets - these were also packed in “aluminium” (mylar?) bags too (with moisture inhibitor “pillows”. They lasted well past their BBE date, but don’t taste nice when eaten straight from the bag - maybe this is something to do with the oil that was used (and possibly the same reason as why the “doritos” didn’t last long)?
4. Beer - different types age differently. I don’t like beer, but I had loads of Fosters and Stella left over from a party. Both had similar BBE dates. After about a year past their BBE, the Fosters cans started frothing when opening (even though they weren’t shaken), and made my stomach feel a bit weird (I was trying to make shandies out of them as I can cope with that!). Stella Artois, on the other hand, was still fine at the same point, and for several months after.
5. Pepperami - I ate one that was 10 years out of date. It tasted fine, and I didn’t die, which was a bonus.

I don’t risk it it with meat so much, but you can usually tell as it changes colour obviously.

As I’m trying to eat less meat and more vegan alternatives, a lot of the alternatives to sausages and burgers etc. last a long time after their BBE. Recently one vegan burger had a bit of mold on it, so I scraped it off before cooking it and it tasted fine - I wouldn’t have done that with a meat version :/

It really annoys me when people throw stuff out the day after something goes out of date. Whatever it is won’t become immediately radioactive/poisonous, are they that stupid?? grrr
