You really have to read From China, With Love: Melamine. While there is no doubt, to me, that we should have a closer eye on China as a food source, if not ban products outright, I am also concerned about melamine added to food from all other sources and origins, including the U.S. Not to mention that the U.S. imports food from other countries, not just China, and those countries might import ingredients from China.
