Jim -
I hope you get an answer because I have this same problem too. I only noticed it on my Seckle pear and not on my other one, of which I don't know the name.

I'm planning on eating the pears as they look fine (so far).

I don't know what the spots might be but it's certain that it won't make the pears unhealthy for you to eat.

There are all kinds of fungal and insect larval problems that affect plants. If something should make the fruit itself unpleasant to eat (rot, slime, or mold) just don't eat it- same as boughten food.

Good luck,

M
