Safety
Cyanuric acid is classified as "essentially nontoxic". The 50% oral median lethal dose (LD50) is 7700 mg/kg in rats.
However, when cyanuric acid is administered together with melamine (which by itself is another low-toxicity substance), they may form extremely insoluble crystals, leading to formation of kidney stones and potentially causing kidney failure and death -- as evidenced in dogs and cats during the 2007 pet food contamination and in children during the 2008 Chinese milk scandal cases.

Famous quotes containing the word safety:
“Love no man in good earnest, nor no further in sport
neither, than with safety of a pure blush thou mayst in
honor come off again.”
—William Shakespeare (1564–1616)
“There is always safety in valor.”
—Ralph Waldo Emerson (1803–1882)
“There was only one catch and that was Catch-22, which specified that a concern for one’s own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to.”
—Joseph Heller (b. 1923)
