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:
“Firm, united, let us be,
Rallying round our Liberty;
As a band of brothers joined,
Peace and safety we shall find.”
—Joseph Hopkinson (17701842)
“To emancipate [the slaves] entirely throughout the Union cannot, I conceive, be thought of, consistently with the safety of the country.”
—Frances Trollope (17801863)
“The Declaration [of Independence] was not a protest against government, but against the excess of government. It prescribed the proper role of government, to secure the rights of individuals and to effect their safety and happiness. In modern society, no individual can do this alone. So government is not a necessary evil but a necessary good.”
—Gerald R. Ford (b. 1913)
