What is the evidence base behind a 28-day beyond-use date?

Asked 27 Apr 2025Modified 15 months agoViewed 21k times

I have continuous temperature data for the period in question, which is unusual and I would like to use it.

I am asking for verification rather than opinion, ideally with something I can read myself.

It is possible the evidence exists and I am searching for the wrong term.

How well supported is this claim?
