I'm really worried just realised I've been eating butter for the last month that is 2 months past its used by date! I dont know how it happened we must have bought it when it already expired. I've been trying to be so careful and now I'm so worried. Do you think the listeria risk from this would be low? Should I see a doctor?
I suspect you will be fine, but if you start to feel ill then let a doctor know what you have eaten. I'm sure you will be fine though :)
I would be at all concerned if it was me. If it was rancid you'd certainly taste it, but even then I don't think it's a listeria risk.
You will be fine. Something being off does not a listeria issue make.
If butter is off you know all about it. It tastes revolting. If you kept eating it I would guess it's fine.
