WASHINGTON (AFP) – A chemical used in explosives, fireworks and rocket fuel has been found in powdered baby formula in the United States, the non-profit Environmental Working Group (EWG) said.
In "little-noticed findings," researchers at the US Centers for Disease Control and Prevention (CDC) found that 15 brands of baby formula contained perchlorate, an oxidizer in solid fuels used in explosives, fireworks, road flares and rocket motors, the EWG said.
"Studies have established that the chemical is a potent thyroid toxin that may interfere with fetal and infant brain development," it said.
The EWG said the CDC study's findings raised "new concerns about perchlorate pollution, a legacy of Cold War rocket and missile tests."
The CDC study, which was conducted in 2006 and published last month in the Journal of Exposure Science and Environmental Epidemiology, said perchlorate could inhibit the absorption of iodine by the thyroid and lead to growth and developmental problems in infants.
For the study, researchers tested samples of baby formula which they had picked up in a local shop.
The two most tainted brands, both cow's milk-based formulas with lactose, had a nearly 90-percent share of the US powdered baby milk market in 2000, the report found.
