At the risk of getting in the middle, from Food Standards Australia New Zealand, hotlinked (bold added)
The food supplier is responsible for placing a use by or best before date on food.
It could be semantics or interpretation of the thesis; other than general guidelines I could not find what would essentially be a table such as
milk : use by date is 14 days from bottling
although it may exist somewhere I overlooked. I did find info applicable in the US, but we are sometimes different.
