But, it's "Safe".
ATLANTA (AP) — Traces of a chemical used in rocket fuel were found in samples of powdered baby formula, and could exceed what's considered a safe dose for adults if mixed with water also contaminated with the ingredient, a government study has found. (...)
No tests have ever shown the chemical caused health problems, but scientists have said significant amounts of perchlorate can affect thyroid function. The thyroid helps set the body's metabolism. Thyroid problems can impact fetal and infant brain development. (...)
The U.S. Food and Drug Administration, aware of the debate over perchlorate in food and water, has not recommended that people alter their diet or eating habits because of the chemical. (...)
The largest amounts of the chemical were in formulas derived from cow's milk, the study said. (...)
The agency issued a statement Friday saying perchlorate exposure is a serious issue and "a top priority" for EPA Administrator Lisa Jackson. EPA officials expect to announce a decision soon about future steps in dealing with the chemical.
The EPA has checked nearly 4,000 public water supplies serving 10,000 people or more. About 160 of the water systems had detectable levels of perchlorate, and 31 had levels high enough to exceed a new safety level the EPA is considering.
