Mince beef - question about use by date

[VincentHanna]

I had some mince beef that was 'use by' the 8th.

It was nice and red still, so I cooked it on the 9th and made a chilli.

There was leftovers from that, which went straight in the fridge that I want to eat tonight (11th) which is 2 days after I cooked it and 3 days past the use by date.

I guess the question is, does the cooking process extend the use by date further?

Well it tasted fine.

I'll let you know if I am alive tomorrow.

We also had guacamole that should have been used within 24 hours, after opening (it was more like 48 hours)
