I had milk where you can clearly taste it turning on its best by date.The general rule on normal milk is 3 days once opened. (7 days on something like Cravendale). I've found that after about 5/6 days it starts going funky. I can't imagine 2 weeks let alone 6. 😆
6 weeks old milk and I’d be vomming just taking the top off.
I bet it was like sludge😷😷🤮🤮
