Wired News: Rocket Fuel in Milk, Lettuce.

A large portion of the United States' milk and lettuce supply may be contaminated with potentially unsafe levels of a toxic chemical used in rocket fuel, according to data released by the Food and Drug Administration on Monday.

The data, part of a preliminary survey of milk and lettuce in 15 states, revealed perchlorate contamination in nearly 94 percent of reviewed samples. The results echo earlier findings by the Environmental Working Group, a nonprofit watchdog that issued a warning about perchlorate contamination in California-produced milk in June.
"The study confirms what we and some other people have been saying for a while -- that perchlorate is not only a problem in areas with known water contamination but for anyone who eats food grown in the U.S.," said Bill Walker, vice president of the Environmental Working Group's West Coast operations.
