My mother-in-law throws anything away that comes from California and has such a label. She refuses to listen to reason. Californians have been slapping these labels on everything, from food to plastic to light bulbs, for years. It's just another way to control people through fear. Unless you're living completely off the grid and make all your food, clothes, and necessities yourself, you probably come into contact with processed, unhealthy chemicals several times per day. A bag of potato chips is the least of your worries.
