As my 92-year old mother is fond of saying, "I bin eatin' unwashed eggs my whole life and I ain't dead yet!" The same goes for vegetables straight out of the (manure-fertilized) garden. She will pick a bean or tomato or an okra pod and eat it while she strolls around the garden. If you were to ask her whether she washed it first, she would say, "What for?"
I agree with a previous poster who said a lot of the allergies, etc. in today's kids might be due to the fact that they didn't eat their "peck of dirt" while young.
As to eggs, I refrigerate them covered, small end down, unwashed. When I get them out to cook, I brush off any visible dirt, crack the egg, and GO.
I also keep a sand covered run and clean nest boxes. The hens have a large, grassy area to roam where their feet can stay relatively clean.
