Since green beans don't ripen all at once they've usually been rained on a few times. The pods look a little moldy. Do the pods need to look pristine for the seeds to be good? I'm hoping the outside of the pods doesn't effect the seed quality.
I would myself worry more about the seeds themselves. If the seed coat is intact, mold free, and of normal coloration for the variety I would feel fairly confident in its quality. Especially if the seed is mature and dried down without wrinkling.
I second what William said. I do notice that after shelling peas or beans I usually have a runny or stuffed up nose for a few days. I should probably do that job outside with a breeze to avoid inhaling the dust you invariably create when shelling.
