Why is melamine dangerous in food?
Animal studies have demonstrated that exposure to low levels of melamine produced no observable toxic effects. Exposures to high levels of melamine, or exposures to lower doses of melamine together with certain other chemicals, have caused urinary tract problems in animals. These have included urinary tract and kidney crystal and stone formation, and kidney failure. Exposures of animals to high doses of melamine over long time periods (years) have been associated with cancer of the bladder.
