Is this safe to eat & or drink? Pear question...

[countryangels]

I bought some pears that I cut up into pieces when they were ripe.
I placed them inside of the refrigerator. Unfortunately, I had to go away for a few days, when I came back I found the pears have a bit of a fermented taste, they have become watery. Originally I was going to blend them & use them as juice.
If they have a fermented taste, is it OK to drink this fermented pear juice?
Is it safe for everyone, young & old ?
One of the uncut pears that I also placed inside of the refrigerator
has some mildew on it, that I should throw away, right ?

Thank you for your help!

Anything with mildew I would toss. If it was in the same container as the other pears, I'd toss the whole thing. If not, slightly fermented fruit shouldn't kill you. At least, it hasn't done me in yet! I don't know that I would give it to littles, though.
