Is there any truly low-lead dark chocolate?

I'm looking for dark chocolate with the lowest amount of lead possible, for regular consumption in the long-term. Mast 80% looked the best in the Consumer Reports analysis, but it's been claimed that Mast is remelted commercial chocolate. Plus it's expensive, which would be fine if it had a flawless reputation, but it doesn't.

It would be ideal to find chocolate processed without the cocoa bean shell (the source of the lead), completely discarding it, but I can't seem to find anyone selling "cocoa bean shell-free chocolate." Maybe it exists, maybe it doesn't. Any pointers?
