Yes, the peaches are safe to eat. Even getting a bite with a worm in it won't hurt you. But you can cut out those areas and still eat the peaches.

For information on growing peaches see our fact sheets Planting and Early Care of the Peach Orchard and Home Tree Fruit Production and Pest Management.
