You know what really bugs me is when you see these top notch cake decorators on tv putting the stuff everywhere on a cake in places that you know are going to be eaten. One show I saw last week, showed the exact same disco I had purchased and it was used on pieces that were definitely going to be eaten unless the baker sent instructions to peel all of that off before eating the cake. They all seem to use it, so we think it must be ok. And I can't believe that they inform their clients that "Oh, by the way, you can't eat that sparkly stuff that's all over your cake!"
I do use it occasionally but I don't sell my cakes, they are for my family and they all know about the disco dust discussions that have been here on CC. If the information has been passed on as to what this stuff really is, well if it doesn't matter to you, what can I say? I know my kids have eaten and passed worse things than that while growing up, as I'm sure most of us have.
I definitely agree that people with certain ailments have to be careful about consuming things that may cause further problems for them. And for that very reason, my father who did have diverticulitus had to be careful with what he put into his body. He loved the cakes I made, but because he knew about the disco dust, he just "ate around it" if I had put some on that particular cake. If he ate somewhere other than at home, he was extra vigilant as to what he consumed, as I would assume most people with dietary ailments would be or at least should be.
It is very true, that this stuff should have never been put out there in the first place if it wasn't considered food safe. However it is there and some will decide to use it and some won't. I guess if the proper warnings are presented, then it's up to us as individuals to decide what lines to step across where our health is concerned and then face the possible consequences as a result. Just my humble opinion....
