What people foods are safe for my dog to eat?

Can my dog eat sausage? We just made breakfast for dinner and left the leftover sausage out for two seconds and he jumped up and got a few pieces before we knew what he was doing. Will he be ok? Two Christmases ago my female got ham and got super sick. So I'm wondering if sausage will do the same? I believe it was like Jimmy Dean Maple sausage.
