His pediatrician specifically ordered the test, examined it, and let us know we had nothing to worry about, so hopefully it wasn't that bad. All I know for now is that it was below the threshold you cited. I'm sorry that that your daughter's test went up, I know that's soul crushing to see happen. When I was freaking out back when I got an email about contamination, I found a study that gave some perspective and made me feel a little better. Obviously for threshold of lead present in any food should be 0, and we should not be complacent, but look at the magnitudes for both the blood concentrations and deltas of IQ they're looking at here: "A highly significant association was found between lead exposure and children's IQ (P < 0.001). An increase in blood lead from 10 to 20 micrograms/dl was associated with a decrease of 2.6 IQ points in the meta-analysis.
