Orange rust - your info says to destroy infected plants
Neighbors plants - she did not - I read this today
Is the Fruit compromised?
Will walking in the patch now risk infecting more plants?
Orange rust has long since not been visible
Will need to note which ones early next year - some we might be able to pull this year
Destroy -- black garbage bag? Burn? How to dispose -- not the farmer they are across the road and not internet savvy. Thought I'd ask as many questions all at once I could think about

you do not specify your crop -orange rust is commonly found on raspberries so I am attaching a fact sheet for how to handle orange rust in raspberries by an expert in OH http://ohioline.osu.edu/factsheet/plpath-fru-30 and another out of PA http://extension.psu.edu/plants/gardening/fphg/brambles/diseases/rust they recommend "As soon as symptoms of orange rust are detected, remove the entire plant. Remove and destroy all wild blackberries and raspberries in the area that might serve as a source of disease. Any practice that speeds the drying of foliage, such as keeping plantings weeded and rows narrowed back, will assist in control since spores need a relatively long period of leaf wetness in order to be able to germinate and penetrate the leaves in the spring. Avoid tipping canes in the fall because transporting inoculum on hands is easy during this operation. No chemical control is known for this disease." I don't think walking through your patch will be your problem - probably going in and pruning well would be your best option - do it on a dry day. According to this out of KY, once a plant is infected it will reduce production and cannot be effectively treated - you may have to rip out and replant next year - you may have to relocate your patch if the neighbor is not willing to do the same for theirs https://www2.ca.uky.edu/agcollege/plantpathology/ext_files/PPFShtml/PPFS-FR-S-6.pdf
I think she will destroy once she sees your info --
The raspberries are OK to eat from infected plant?
Reason for question is I think I remember which were affected but there might be some idiots not see and do not want to cause harm to anyone
I can look at the leaves of the ones I know we're affected and then at others if you think it shows

Generally, you only get the rust fungus on the leaves and the canes, as long as there is no rust on the berry itself, they should be fine to eat, that said orange rust generally greatly reduces the berry crop. I could find no evidence anywhere for orange rust toxicity in humans. I did find an article which gave a natural antifungal you might try - you could try spraying your raspberries with a mixture containing neem oil. I don't know how effective it is but none of the ingredients are toxic:
To make your own Neem Oil pesticide & fungicide spray.
- 2 tablespoons neem oil (if it's a bit thick, mix it with 2 tbsp of almond or olive oil, to loosen it)
- 1 tsp peppermint oil.
- 1 tsp rosemary oil.
- 1 gallon water.
- Pour ingredients into a large sprayer and shake well. Spray on affected plants (top and bottom of leaves).
