Yeah ... and most people would be surprised at what tests would show are in the food they prepare at home due to what they use to prepare them in and on, and what they are served on. Those hard heavy plastic plates and bowls found in many cupboards and many many restaurants can be made of melamine and microwave heating on or in those releases trace compounds into food.

Thing is .. the melamine that is harmful is the finely powdered stuff added to foodstuffs to fake out the protein tests, the powder travels to the kidneys where it clumps up and interferes with kidney function, to the point of failure.
