The problem with being snarky about Red State Blue State malarky is that some issues affect all of us. As a nation, these are policies that we've voted for, whether we know it or not, and it disturbs me. Why was Swift boat service more of a topic of the election than perchlorate? or a dozen more pertinent examples? Some of the blame can be placed on our joke of a national media, but the Kerry campaign has to bear some of the blame as well.....
Rocket Fuel in Milk, Lettuce:
The Food and Drug Administration says a rocket fuel component contaminates nearly 94 percent of the milk and lettuce samples surveyed. The compound is suspected of having nasty effects in humans. By Amit Asaravala.
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.
Perchlorate is both a naturally occurring and man-made chemical. It is used by the aerospace and defense industries to help rocket fuel burn. In humans, high concentrations can disrupt the thyroid gland, which regulates metabolism and is linked to the development of motor skills in children.
In its survey, the FDA found an average concentration of 5.76 parts per billion of perchlorate in the 104 milk samples it studied. In 128 samples of green leaf, red leaf, iceberg and romaine lettuce, the agency found an average concentration of 10.49 parts per billion.
Federal and state agencies are still debating just how much perchlorate is acceptable in human diets. California health officials recommend that drinking water not exceed more than 6 parts per billion of perchlorate. The U.S. Environmental Protection Agency, meanwhile, recommends a stricter 1 part per billion.
"It's subtle," said Walker. "It's not like you're fine today if you get 6 parts per billion (of perchlorate in milk) and then tomorrow you drink a glass with 7 parts per billion and suddenly you're sick."
He added, however, that people with existing thyroid problems and pregnant women should monitor the total amount of perchlorate they ingest each day.
"We found that there are some people out there -- like the 1.6 million people of child-bearing age -- who are eating a diet very heavy in lettuce," he said. "This could be exceeding the EPA's recommended safe dose."
Though the FDA study didn't explore how perchlorate gets into lettuce or milk, scientists believe it enters the water stream through industrial leaks. It is then thought to be taken up by, and concentrated in, plants and animals.
The National Academy of Sciences is currently reviewing the EPA's assessment of the risks of perchlorate. A report is expected in Jan 2005. The FDA said it would wait until then to decide whether or not to enforce limits on the amount of the chemical that can appear in food products.
