I wouldn't, but then that's because I have "ishoos" stemming from getting horrific food poisoning from off milk at work. Incidentally it was previously unopened and within it's best before date when I had some, so I was just unlucky (and it tasted foul and only had one mouthful).
However, it's made me totally paranoid about out of date foods, so I would say YANBU, just braver than me lol.
