> > Perchlorate inhibits iodide uptake and may impair thyroid and
> > neurodevelopment in infants. Recently, we unambiguously identified the
> > presence of perchlorate in all seven brands of dairy milk randomly
> > purchased from grocery stores in Lubbock, TX. How widespread is
> > perchlorate in milk? Perchlorate in 47 dairy milk samples from 11 states
> > and in 36 human milk samples from 18 states were measured. Iodide was
> > also measured in a number of the samples. Perchlorate was detectable in
> > 81 of 82 samples. The dairy and breast milk means were, respectively,
> > 2.0 and 10.5 g/L with the corresponding maximum values of 11 and 92 g/L.
> > Perchlorate is present in virtually all milk samples, the average
> > concentration in breast milk is five times higher than in dairy milk.
> > Although the number of available measurements are few at this point, for
> > breast milk samples with a perchlorate content greater than 10 g/L, the
> > iodide content is linearly correlated with the inverse of the
> > perchlorate concentration with a r2 of >0.9 (n = 6). The presence of
> > perchlorate in the milk lowers the iodide content and may impair thyroid
> > development in infants. On the basis of limited available data, iodide
> > levels in breast milk may be significantly lower than it was two decades
> > ago. Recommended iodine intake by pregnant and lactating women may need
> > to be revised upward.
