Thank you for the warning regarding chemicals in Farang Chae Buay. But it is so delicious na. :( As a toxicologist, i used to set safety standards for air, soil and water at the U.S Environmental Protection Agency. Here in Thailand, I try not to think about it too much cause I think I might go crazy na. ;) I know that Was has a better idea in the future. . .nontoxic vegetables. Yes good idea. I like to eat fruits and vegetables so much and don't want to worry about chemical contamination.
