The Associated Press reported that the Food and Drug Administration has set a standard for the amount of melamine found in infant formula: one part per million.

The development comes days after The Associated Press reported FDA tests found traces of melamine in the infant formula of one major manufacturer [Mead Johnson] and cyanuric acid, a chemical relative, in the formula of a second major maker [Nestle].

This all begs the question, why is melamine in food to begin with?
