Getting the Lead Out

We just got back soil test results for our new garden, and the lead levels are unfortunately pretty high (around 800 ppm). Now what?

We obviously should have tested the soil *before* starting the garden, but we now have a variety of plants growing out there, and we're not sure how concerned we should be about eating them. The research I've done has said anything from "Just wash them thoroughly" to "Don't garden if the lead is above 300 ppm". Should we kill the garden and start over with raised beds, or just eat what we have, or...?
I should note that the soils have already been remediated somewhat, and they are slightly alkaline, which is supposed to bind the lead and keep it unavailable to plants. Also, no children will be eating the food.
