I asked this question a long time ago. Received blank no answers. No
data on www as to the question.

You didn't look. I found more data than I can use in one search.

The question is whether apples from a diseased cedar rust have any
harmful affects upon humans eating them?

I was wondering also whether it is advisable to cut down and eliminate
apple trees that are badly affected and whether it is good practice for
those remaining apple trees. A practice of finding tree varieties that
are resistant to cedar rust.

No, best practice is to eliminate the causes of cedar rust. This means
eliminating infected plants (mainly junipers) that are carriers,
observing proper hygiene, and controlling outbreaks with fungicide if
necessary.

I have some old mature apple trees that seem to have zero cedar rust and
I have some new young trees that are loaded with cedar rust. So I wonder
if a practice of simply eliminating all cedar rust trees and keep
planting varieties resistant to rust is the best practice.

If you have an unlimited budget for nursery stock, sure, go ahead.
Most of us who have apple trees prefer to keep the trees we have and
carry out the tasks necessary to keep them disease-free.

I have a bad feeling of walking past a apple tree in the grove that is
loaded with the rust and the looks of it is just ugly.

I cannot change the cedar part of this disease. So I wonder if a
constant replacement of apple trees resistant is the practical answer to
the problem.

No, you d**n well can. You clean up the source of the infections. You
keep your orchard clean. You control outbreaks. In other words, you
start being a gardener and stop being a fool.
