i mean its safe to eat, but i wouldnt like to be breathing/swallowing it constantly. a few years ago my dad and sister made a cake and we started putting drops of food coloring in the icing or whatever, i guess we were supposed to mix it in (i cant cook outside of the microwave) but it tasted like crap and afterwards I got sick to my stomach. So i dont think this lady is mixing the food coloring into icing
