Gotta love this headline in the WaPost:
Perchlorate Levels in Food Safe for Most, FDA Says
Huh? Here's some background into this delightful inadvertent food additive from the FDA's own website:
"Most of the perchlorate manufactured in the United States is used as the primary ingredient of solid rocket propellant. Perchlorate is also used in pyrotechnics, such as fireworks, gun powder, explosives, and highway flares. In addition, perchlorate is used in a wide variety of industrial processes, including tanning and leather finishing, rubber manufacture, paint and enamel production, and additives in lubricating oils.
In recent years there has been increasing interest in perchlorate levels in soil, ground water, drinking water, and irrigation water around the country and what health effects these levels may have. Human exposure to sufficient doses of perchlorate can interfere with iodide uptake into the thyroid gland, disrupting its functions and potentially leading to a reduction in the production of thyroid hormones."
Today the FDA assures us that:
"Levels of a chemical used to make rocket fuel found in commonly consumed food are not high enough to pose a health risk to most people, including children and pregnant women, U.S. regulators said."
