Calif. lettuce contains toxins
Published April 28, 2003
Laboratory tests showed 22 types of lettuce purchased at supermarkets in northern California were tainted with perchlorate -- a toxic rocket fuel ingredient that has been found in the Colorado River.
Tests at Texas Tech University found the substance but also concluded the test sample was too small to draw conclusions about the lettuce crop eaten by people across the United States.
The Environmental Working Group told the Los Angeles Times the test results were serious enough to warrant a call for the Food and Drug Administration to conduct its own investigation into U.S.-grown lettuce.
