A scary new under-the-radar CDC study has found that 15 infant formulas sold in the US are contaminated with the rocket fuel additive perchlorate—which is even worse than it sounds, because so is the tap water parents mix formula with.
From the Environmental Working Group:
Researchers from the U.S. Centers for Disease Control and Prevention (CDC) have reported that 15 brands of powdered infant formula are contaminated with perchlorate, a rocket fuel component detected in drinking water in 28 states and territories.
The two most contaminated brands, made from cow’s milk, accounted for 87 percent of the U.S. powdered formula market in 2000, the scientists said.
The CDC scientists did not identify the formula brands they tested.
The little-noticed CDC findings, published in the March 2009 edition of the Journal of Exposure Science and Environmental Epidemiology, raise new concerns about perchlorate pollution, a legacy of Cold War rocket and missile tests. Studies have established that the chemical is a potent thyroid toxin that may interfere with fetal and infant brain development (Kirk 2006).
