Is it okay to eat yogurt that's been at room temperature for a day or two if the seal hasn't been broken?
Even if it's not contaminated because it is sealed and pastuerized, it may do something nasty to your digestive system because those "active cultures" are now "very active cultures".
In common terms, you may find yourself full of gas to the point of pain or at the least to the suffering of those around you.
I'd pitch it unless you were going to use it in something cooked.
Its worth the pain. Eat it.
What if it's soy yogurt?
I'm actually more inclined to eat it, because it happens way too often that I take a yogurt to school in my lunch and then don't eat it and it gets left in my bookbag till the next morning. But I don't want to get eaten alive by those "very active cultures."
I was only joking, because of his signiture. I would never eat (or drink) soy anything.
