"Using infrared lasers and light spectroscopy methods, Lisa Mauer, an associate professor of food science, was able to detect melamine in baby formula at one part per million in about five minutes or less. Melamine, a synthetic chemical used in plastics and other products, has been found in baby formula and other milk-based products imported from China. High doses of melamine were associated with cancer in some animals, and it is especially dangerous for infants, according to the Centers for Disease Control and Prevention. "

"Testing by the FDA and Cornell University has found melamine in samples of recalled pet food as well as in crystal form in the urine and kidney tissue of dead cats. They’ve also found the chemical, in apparently raw form in concentrations as high as 6.6 percent, in wheat gluten used as ingredient of the recalled cat and dog foods, said Stephen Sundlof, the FDA’s chief veterinarian.
“There was a sizable amount of melamine. You could see crystals in the wheat gluten,” Sundlof told The Associated Press."
