I wondered about this. I'm allergic to penicillin, anyway.
The problem isn't the penicillin
The problem is that the amount of penicillin in a slice of bread is so miniscule that you'd need to eat a vast amount to receive a medical dose.
Bread mold also has a shit load of toxins that vastly outnumber the amount of penicillin. These mycotoxins over time cause liver, kidney, immune system, brain and heart damage, hemmhoraging, ovulation disruption and damage to semen production.
That's what's gonna kill you first.
I have a question:
If you get pre-sliced bread, and one slice has visible mold, are the other slices ok. Some people I know find it gross , but I've been doing it since I was young because my mum said it's ok
Mold has invisible root networks throughout the porous material of the bread. Also, the spores get airborne so it's likely that it has spread through the rest of the bread.
It's literally impossible with the naked eye to tell how far it has spread, so best case scenario is to chuck the whole loaf.
